yea AWD and a car thats built to do it stock is a nice start lol

my boy still has the fastest stock GT-R 1/4 ET as well i believe. think it was a 10.29? i'll have to look it up. it's on GTRlife forum.

I must agree! This having to re invent the wheel thing quite frankly sucks! Gosh could you imagine if our Z Cars could go deep 10s stock!? :happydance:

yea i mean this rumor of a turbo'd V6 merc engine going into the next Z with 400+ HP is quite interesting. a stock turbo engine is a great starting point for modding. taking a NA engine like we do and going boost just starts trouble from the start lol

oh and i found his times.

rocking my 28" street radials now. might go to the track in the next week or two.

Oh snap! Dem's big!

You can run these tires on the spare rim....
Mickey Thompson Sportsman SR Fronts 26X5.00R18LT 79H

I am currently using these from my fronts....running 40-50psi....They are rated to handle the speed.

^^ Are you sure that isnt a 26 x 6? I cannot find a 26 x 5 x 18 MT SR anywhere, not even the MT website.

do those clear sport brakes by chance? cant really tell what you're runnin in the pic.

Not a chance!!!! I currently have rear base model 350z brakes on, and I still had the grind about .050" off the calipers. Once you make the required modifications to the dust shield, the brake conversion takes about 30 minutes or less. I dont mind doing it since the wheels obviously come off anyway. Its literally just 2x 19mm bolts and 1x 12mm banjo bolt per side to change the brakes.. thats it. Then a few pumps of the pedal to bleed each side.

I know 99% of you guys cannot STAND the idea of doing this before going to the track. Trust me, I resisted it too. I had 18x12" wheels with 315 drag radials and nearly zero baseline camber and it still couldnt leave hard. That 18x12 setup will now be my standard daily driver, and this will be my track set. I am selling my 19x11 rear volks because even on 305/30/19 R888s, having the turbos is almost pointless until 60mph.

I dont have to change the rear brake every single time I swap wheels... because the ugly factor is the only reason to bother taking off these rear brakes anyway. I have stoptech rotors and pads in there, the single piston surface area isnt TOO far off from the piston size on the akebono rears... To be completely realistic, I am just not going to notice the difference on the street even with the HP I have and speeds I go. So I will probably only put the rear akebonos back on occasionally.

Stay tuned for a write up post on putting 28s on the car. Its very cheap and easy, and is going to make the drag strip WAY more amusing. The diameter will have an effect similar to a longer final drive, and the gobs of sidewall will make it SO much more forgiving to the ridiculous camber gain.

well you go to the track and show me a 60' time thats worth doing that much work and i'll jump right in lol

but just for going here and there and N/A that seems like a bit much. for me driving my car daily and to and from the track i just think thats a bit much lol

My car is a daily driver as well. It has over 60,000 miles on it and I will be driving it 90 minutes away to the track with these wheels on it!

But yes your point about it being a bit much for NA is definitely accurate.

my first choice originally was your inital set-up of 18x12's with 315 DR's.

found cheap set og ROTAs in that size for only $275 each but i heard they dont clear the rear brakes either. not interested in shaving the monblocks just for a few track runs lol

do you know of any 18x12s that'll clear?

worst case i may just give up and get the 305/30/19 mickey thompson DRs lol put em right on the sport rears

I dont know if any 18x12 will perfectly clear the sport brakes. I would recommend the Rota 18x12+20. They are cost effect and perfect size and offset to get the most grip youre going to get with your sport brakes on. Plus, I can confirm their fitment and function... I am the one who uses them on here.

They only just barely didnt clear the caliper. Grinding them down takes no time at all, and you dont have to take off a ton. They are just cheap akebono calipers and they certainly are not monoblocks! I feel no guilt grinding on them. Sure I would prefer not to... but I wasnt going to spend 3 times as much on different wheels and risk finding out the hard way that they didnt clear any better.

Since they are off the car right now... see for yourself:

Got my 305s for the rear today. Needed new tires before I was ready for new wheels so they are going on my 40th wheels. I really want to put them on but I still have 3/32s worth of tread left on my existing rears...not wasting that! Time to do some launch practices.

I love the flames. Man the rubber feels soft.

looks good. not sure if i could bring myself to grind the calipers personally lol

wonder how big of a grip difference is between 18" DRs or 19" DRs

Time for the 10s.
 

i'm running 305 RE-11s on my oem rays

http://img.tapatalk.com/d/14/08/19/azebaver.jpg

I have to believe 19s have more grip. They have more surface area on the ground. Look at dragsters. I have to believe 19s are better for the 1/4 mile and 18s for the track.

soooo find me a spare set of Ray rears for a couple hundred bucks and grab me some mickey thompson DR 305s lol

18s will give you better grip.

wheel diameter does not effect surface area on the ground, that is tire diameter.

smaller wheels give you more sidewall, and more sidewall gives you more grip. This is because it allows the tire more compliance. More sidewall also increases drivetrain cushioning, softening the blow to things like your axles.

The advantage 19" has over 18" is less/stiffer sidewalls and less compliance. This is ideal for responsive handling, but the opposite of what is ideal for drag racing. 19" is going to hook up worse and be more likely to break your axles... but it will feel more sporty and confident in the turns.

Most drag cars built from actual cars that use anywhere near typical tire diameters use 15" wheels for drag racing.

i know all this from growing up with a father in drag racing. sadly i just need to enjoy the Z as is and go build a full out drag car lol

that seems to be the move to make i feel.

That makes a ton of sense. So it is the sidewall of drag cars that makes them so sticky, not the actually diameter. Interesting. Thanks.

Yup.... most cars are no good for drag racing if you show up slammed on 19s. The 370z happens to be one of the worst to try that with. Coincidentally, 370z owners are generally not the type willing to show up any other way. Hence our really sad 1/4 mile registry for the boosted cars.

i was happy with my 12.89 for N/A and being 5th but that didnt last. hence why i was thinking about making some changes and taking a higher spot.

Its both!! Its everything! Diameter and Width create the available contact patch. Alignment determines how much of the available contact patch you get to use. Lots of sidewall gives the tire more compliance to smush into the ground and increase surface area while reducing drivetrain shock by absorbing energy that it releases/unwinds as you go.

Many other cars with the same HP as mine wouldnt need the 28" drag tire on 15" wheels. But the 370z cambers so hard when it squats that I need the big sidewall's added compliance to regain some of that lost contact patch. I am hoping it will smush down into the road and let the car grab some pavement for once.

With a proper drag racing suspension, these 28" tires on my Z are WAY overkill. The guy down the street from me who bought my old dyno is running high 7's and low 8's on the same exact tire with his Mustang.

This made me laugh and quoted for truth. Tire, not shiny wheels, win drag races.:bowrofl:

If you want shiny wheel and win drag race, you buy so much GTR.

Yes my bad....my first post was a typo....they are 26 X 6....however they are able to be properly mounted on a 4.5 to 5.5 inch wide rim which makes the spare rims perfect for them

:iagree: Rep Points added!!!

Great knowledge sharing here brother....Hence the reason why phunk has gone the route of doing the rear brake set up in order to run the 28" slick on the 15" rim....

Very true man...I have gone back and forth on this....and building a Z as a drag car is expensive as hell....I've pretty much become content with what the car can do on the 1/4 mile...its not the fastest car out there that's gonna break records, but its quick enough and can hold its own....

Overall the Z's a nice car...quick....great all around. ..but its not a great platform for a drag car IMHO......unless ur completely sponsored or got tons of money to splurge....or willing to do some serious mods like phunk....Dont get me wrong...phunk is doing a great thing with lots for others to learn from....but I just cant see myself doing all of that to my Nismo....My hats off to phunk....:tiphat:

Its cheaper to build another car as a strict drag car..but for a daily driver/head turner/road car for those spirited driving moments, the Z does it for me...the guys out here think I'm nuts to drag my Z and think I'm abusing it...to a lot of guys out here from where I'm from a Z is a car that you would floss....Although there's quite a few of us that own 370's out here u would only see 2 or 3 of us 370Z owners actually racing our cars at the drag strip.....you have a better chance of finding a big Z34 group out here at a Fatlace show ...Lol

I can understand your position as well.

I have no interest at all in turning my Z into a drag car.

However, I am willing to spend a hour or two and $1000 into parts to make it so when I do wish to occasionally drag race my car, I can actually see what it is capable of. Not only for my own satisfaction... but now when people ask what the car can do in the 1/4, I will be able to give them a straight forward answer. No more pulling out the excuse list and making them roll their eyes at me.

I am not sure why you guys consider wheels and tires to be serious modifications. It is actually quite the norm for drag racing. If you spend a day at the track, you will see far more cars on tires like my 28's, than you will on 19" volks or works LOL

for me i am more interested in 18s that clear the akebonos with DRs or my 19 rays with DRs. personally i am the same with not wanting my Z as a drag only purpose car. i just wanna drive to the track, swap wheels if i have to, put the others back on, and go home. no grinding calipers or modding parts. just put on the stickies and run it lol

i have been looking at wrecked 370s lately thinking about maybe taking one, stripping it down, shaving all weight, and starting with bare bones and a engine to make a drag only car lol

I guess it just depends on how bad you want it to go well! The car is never going to leave to its potential on 19s. 18s are better, but still not that great and many wheels will already require caliper modification. But once you see how minor the caliper modification is you will get over it quickly... it takes only a few minutes per side and its done and its like it never happened and you only have to do it the one time.

If you want to build a dedicated drag car, I would highly recommend avoiding a 370z LOL.

ughhhhh it would be a struggle to come to terms with shaving my calipers even though no one would ever see it....i would know lol

but i agree 18s would be so much better than 19s its just fact.


ooooo cmon a full out 370 drag car? why not? lol :stirthepot:

:bowrofl:

I finally took my Z out for a test drive on the 15s with 28s last night. All of you guys who cannot stand the idea... if you felt what its like to dead hook first gear with 600rwhp you would change your tune quickly. I am very impressed with how well the car still handles on these tires with 22psi in them for the street. The car actually rides really nice with these too. I am very happy. I would take them off before doing any extreme high speed highway pulls... but for spirited driving under 80mph around town they feel just fine and man is it such a good feeling to floor it and not spin.

If it really kills you to grind them down, send them out to Mike for a fresh powdercoating afterwords... then they will be better than new!

why would you tell me this :shakes head:

phunk you're the damn devil.......but i like it lol this will have to be considered.

im just trying to get you to crack because youre being difficult about it! and i dont really like being the only guy with grinded calipers! :)

well if youre the only one then theres a reason lol and im a sucker for peer pressure dammit lol

go look back in the OG thread when i got ganged up on by 4 of them about tires lol

phunk I totally get u and why ur doing what ur doing.....This forum and the drag guys will benefit and learn a lot from the stuff ur doing.....I guess I would probably do the same if I was on a F.I. set up so I could actually see the full potential of the Z....

Your absolutely right about the whole tire thing...Surprising how not much people don't get it..but it's drag racing 101....U gotta have the right foot wear/foot work (tires, rims, suspension) in order to put that power to the ground.....Considering ur last post of doing a test run with the 28's, I'm stoked to see what ur set up will do in the 1/4 mile....

If you have the sport package, just get 18 x 10.5 + 12 offset rims I have volk t-37s and M/T 305 35 18 drag radials fit perfectly. You can put the 26 X18 X 6 M/T sports man tire on the spare tire rims on the front, 36 lbs tire and rim vs 53 for the stock tire and rim.

The car goes perfectly straight down the track with 21 to 23 lbs of air in the back, and 48 to 50 lbs in the fronts.
All motor with bolt ons getting 1.80, 60 ft. times .
