DRAG WHEEL/Tire setups

Love to do quick little pick ups here and there when it's safe.
Mostly rolling spurts from 2nd, 3rd, and into 4th...backing off at about 110 or so.
It was my dd up until this past year.

Used to race when I was a kid ... when a 15 second 1/4 was a really really fast time...Corvettes, GTO's, Hemis, and Super Sports were running in the 15's and 16's.

Got the urge to track it a few weeks ago and am now on a mission to eventually get in to the 11's

Best run at Island Dragway (NJ) was 13.02 @116 mph with a 2.0 60'
The other runs were 13.1 @ 115 ... never got under 2.0 60' times

No traction and had to nurse it until I was able to shift into 3rd because of the wheel spin and hop...not fun

Track temp was in the 40's...(summer tires ... ugh)

Did as much research as possible ... and a lot from this site ... not too many Z's around here.

Came up with the need to further research the ABLS and yaw sensor and the effects it has on 1/4 mile.
(?) It is my understanding thus far, that the ABLS is not disabled by turning off the VDC and will pulse the brakes during wheel spin.
Verified this at Broadway Performance Speed Shop - by attempting a controlled burn out and hitting the brakes after releasing the clutch and creating the spin.
The rear wheels went in to a stutter mode when the brakes pulsed.
The ABLS seriously inhibited the ability to do a burn out.
I guess this is why the drifters don't like the ABLS



The Z is a Base/Sport and has:

6MT trans / ACT clutch

Stillen SC'r with a little over 8 lbs. of boost

PPI Long Tube Headers

Quaife LSD - 4.08 final drive I believe (I should know but I don't) ... will have to double check on that one though - installed within a few months of the SC'r because of the traction problems even back then.

HKS exhaust/cat delete

Custom Tune by John Nouri - Broadway Performance in Passaic NJ

Stock Suspension - not lowered - Almost 57k miles on the car now
Don't know if it's time to replace it...has seemed to be OK

Stock 19" Rays with 285/35/19 Michelin PS II's
I do have 20mm spacers all around though

Am considering the GTM Race Logic TC with launch control as a means of stabilizing and standardizing the launch...
Not intending to rev it till it sputters and pops tho' but rather give that extra bit of buffer during hard acceleration.

Any and all input on that would also be appreciated as well ...

I do have an extra set of 19" OEM rear wheels and the next logical step would be to Slap on the M/T's ...
The M/T's are a bit taller by about a 1/2" and have about 3/4" wider sector width than the PSII's.
The 20mm spacers were a good idea at the time ... :-) ... made the PSII's look good ... hence the fitment question.
Would like to avoid having to change the wheels at the track tho'

Thanks,

Bob

Also find 2 wheels, only two in the 17"-18" size by apx. 10" wide. You can race with spacers in the front. As far as the rear, Jegs can help you get the right offset/size to fit your car, w spacers or without. Weld wheels was my choice for the slicks, but they Jegs can help you.

Get a good rear set up that can be put on your car hours/days before you go to the track. On that day JUST drive to the track with those tires/wheels on, & the stock setup in the front. If you can get a front brake lock-up system or I think you can just remove the rear brake fuse??/ then all you'll do is drive to the track, have a cup of coffee, pull into the water box first, lock front brakes & smoke the rear tires till a bunch white smoke appears in your side & back mirrors. The starter will also wave you to go forward to the starting line. Part of their job is to tell you when your ready. Lift the clutch & floor the gas at apx. 4,500 to 5,000 something rpm. Experiment. You should be able to do 1.5 to 1.7's 60' times & very good 1/4 ET's.

Not much to do at the track & do great times & have fun. Good luck. Also it sounds like you have a very nice setup....

I did that when I stated with my 08 z. If you go to dragtimes.com, browse, hit Nissan 350z. I'm on the first page(bottom) Someone made a video of my run with the exact set up I just mentioned. I didn't even hear of forums then. Soon I was told that the run 12.9 put me in the # one spot of 350z.com. I didn't know or care at that time. Had stock wheels/tires in the front....

I installed them into brake compartment under the hood<
Getting the proper fitting is very difficult.
I had custom hoses made up.

Gleaning from the wealth of info on this thread - I might be able to do a good burn out by removing the Rear Brake Fuse ...
Hit the Gas, Pop the Clutch, and very quickly Left Foot the Brake ?

Now all I gotta do is learn about the suspension - digest it all - and apply it properly at the track!

Is your car K51 Liquid Platinum or Silver .. ?
Mine is the Liquid Platinum ... will have to post a pic of it sometime

BTW 12.343 @ 114.14 ---- and (gulp) what broke ?

On a Side Note...FINALLY!!! A solid group of Drag Racing enthusiasts on this forum. For the past couple of years its been so hard to get some good info....Like all of you have traction issues...NA at the moment...Can't break 2.0 60 ft at the time....Need Drag Slicks...Thinkin of going Mickey Thompson Et street 2 305/35 -19 on the back, but need confirmation that the diameter size will be ok....Can anyone confirm if these will fit on stock height no spacers?
