Wheel Sizes & Offsets For Skylines

[AMR33]

Hey guys great thread. I have had a look but would like some recoomendations as to what numbers to use on my R33 GTS-t. This car will be used predominantly on the track and I prefer 17" wheels (thinking of Rota grid, or P45R or something similar). Im also thinking of going with a staggered set up (9-9.5 rear and 8-8.5 front). I want to run some nice wide tyres also. Questions is, what do those who do track days recommend from their experience?

Cheers

Hey just want a quick answer. Going to buy a set of Lenso D1R's for my daily R33. Would 18x9 +32 (Front) sit flush in the guards

18×10 +22 (Rear) sit flush in the guards

Or what issues am I gonna get

Just like to hear some feedback to help me out.

Assuming Gtst. Fronts will sit inside about 10mm, and rears outside about 15mm. This depends heavily on camber though. I have 18x10+38 which after resetting camber to 0 now sit flush, maybe the tiniest bit of poke, whereas previously looked like they had heaps of room.

Yeah it is a gtst. Thanks for your help...if i went 18x9.5 +40 in the front, would that sit flush with guards?

[M@&k]

12mm wider rim, so 6mm either side. But 8mm larger offset, so will sit in 2mm more than 18x9+32.

You'll also have clearance problems on inside with offset larger than around +25 with 9.5" wide rim.

Best if you learn how to calculate offset, or use a calculator on the net.

My recommendation would be to use 18x9.5+22 with 235s and roll guards to fit. Not too difficult or expensive and proven to be a good combination for 33 gtst.

The lower the offset the more likely it is to get to flush

I you went 18x9.5+40 you won't get shit cos it will foul on the upper control arm.

I went for a staggered set of track rims last year (17x8.5 +30 front and 17x9.5 +38 rear) but changed to a square setup this year (17x9 +35 with 255/40 tyres) for the increased frontend grip and being able to rotate the wheels around the car as they wear.

Similar to what i have done, just with 18's

[joeyjoejoejuniorshabadoo]

should have stuck with round wheels man...

Skyline model = R33 GTS-T
Wheel diameter = 18
Wheel width = 18X9.5 Rear - 18X8 Front
Tyre size = 255/35/18 Rear - 235/35/18 Front
Modifications to fit = Guard Rolling

What's a good offset for Rota Grid Rs in 18x9.5 all round on a 33 gtst? Thinking +35 all round. Will only go as far as rolling my guards.

I think heaps of people run +22 all around with little tyre. Might want to check front clearance before you go putting money down.

Did you notice any oversteer with the square setup?

Didn't notice a difference in oversteer with that change. Your suspension setup, alignment and how you drive the car will affect that.

Offset? Photos?

Agreed, you'll definitely run into inner clearance issues with +35.

Honestly, if you're willing to roll guards just get +22 with 235/40/18s and be happy. I didn't get 9.5 +22 and sometimes wish I did.

[AMR33]

Im thinking of getting 17x9 +25 for my r33. The guys at Rota recommended this and said the widest tire I can run would be a 255. They also said I will have better clearance with +25 than with +35.

Does this sound right to you guys?

17x9+25 all around should be fine. I'm running 18x9+20 all around with 245/40s.

5mm won't make a lot of difference.
