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.

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.

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 :)

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?

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.

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?

Cheers

    • Ha, I've never pressed the X in all these years incase it removed the notification for all Admins
    • I don't know, I've never done it that way, but 1. While it is an interference engine, there is still clearance between the valves and the piston at all points in the regular timing cycle 2. There is not a lot of distance before you can't catch the top of the valve stem any more I don't know if 2 is greater or less than 1. But 3. If it doesn't work out you are f**ked, engine is coming out to disassemble so it is a big bet.
    • Semi slicks are horrible for road use, just use a high performance road tyre unless you really need the maximum grip. Noisy, unpredictable (amazing, until they are not), expensive due to very high wear and not good in cold and particular wet. And yes, it is a thing to store cars on stands instead of tyres if you know they are going to be parked up long term.....but who ever realises that a short park is going to stretch into years before it is out again!
    • I know in Australia you'll definitely get above 30c. Parked in the shade in Summer you'll be above that. 😛 But in cooler climates, you might get that warm driving on the highway for a bit, but you'd never get to full heat temp. I'll try and find some of my historical tyre temps between Aus summer and winter (be aware immin the warmer area of Aus too.)
    • I get that taking off the head is best but that's a bit much for "just" valve seals. I was just under the impression that one would be able to rotate to TDC and be able to temporarily drop the valve without losing it and effectively having to remove the head to then recover it. I never knew people actually pushed rope into the cylinder to do valve seals hahaha So just to confirm, just going to TDC will not work? In that case I know when I do valve seals I'll maybe just remove the head and do some other things while I'm there, or just wait until I do an engine build.
