My wheel setup and what tires size

phunk

I only meant that once boosted.. the power that these cars make needs as much tire as you can fit! Then again, with how much this particular IRS cambers on compression, I am not sure how much the extra rubber really matters when it isnt touching the ground!

This x 1000.

I had my first autocross (hard launches) since I changed suspension set up (a LOT less rear suspension squat) and its the first time I haven't been able to roast through first and into second, and I'm N/A and making more power and tq than I ever have.

This suspension just adds camber so fast when compressed that it's hard to put power down, no matter how fat your tires are. I think this is why some people have worse straight line traction when they go to larger tires...

Hi guys! sorry for bring this thread from the dead lol! I have a question and I already search a lot but can't find the answer. I'm going to buy some wheels, the wheels specs are 18x9.5+22 & 18x11+16. I want to know what is the best tires combo for this wheels for the track and the street, my car is daily soo haha!. I was thinking to install 265/35/18 and 285/35/18 cause here in PR find a tire more than 285/35 is like find gold My question is... I can run those tires with out having problems with the traction control? My suspension setup is basic... Swift Spec R springs, stock shocks and SPC rear camber arms. Thanks

You shouldnt really have a choice. You need to keep the tires 10-20% over the wheel and within 0.3% of each other front to rear. This is proper and correct.

Run the 285's on all 4 corners.

Hi I am actually thinking to run 285/35/18 square but having headache to get right size rims. What is your rim spec(Front and Rear) and do you use any spacer in the back to make it not "sunk"?

I am looking at Advan TCiii18x10.5 offset 25 now but get info the front may rub (Suspension still stock yet so not much camber i can adjust). It would be great if you can share your experience. Thank you for the help!

My rims are 18x10.5 +30 and I run 15mm spacers on the rear. +25 up front should work but 27 plus would better.

Thanks a lot for the info guys! One more question... If I go with 285/35/18 on front, with my 18x9.5+22 wheels, they are going to rub with the fender liners? I dont have camber plates on front... I know that the rear setup works great... If someone have pics of the 285/35 on the front are going to be great!

Thanks!

Not the exact setup you're looking at but here's my Z with 295/40-18's on 18x10 +30 up front. I had a tiny bit of rub but your 285's will be ~1.5" shorter than my 295's were so you should be fine.

Also our cars don't use camber plates. If you want to adjust front camber you'll need aftermarket front upper control arms.

Thanks for the info you provide me bro and for the pic

Maybe this is a stupid question but, With my OEM upper control arms I can install the 285/35 tires right? Eventually Im going to finish my suspension setup lol! But for now Im going to leave it like that... when I install the new wheels & tire setup (285/35/18 square setup) Im going to take the Z to the Alignment shop... My car is not a daily any more, so I can give her a full track alignment If you guys have any recommendations for the alignment are going to be great!

Thanks!

carlitos_370z

I need help! I want to know if i can this setup.
285/35/18 front and 295/35/18 rear... I install the 285/35 square but my rear wheels are 18x11 and the tires looks stretch. Any helps are going to be great. Thansk

ChaseZ

325/35 = no stretch

carlitos_370z
