Hi all, I've just bought some piaa Nakajima racing wheels the stats are;

All tyres are federal 595 rsr's

Fronts 17x8 et 38 with 235/45/17 on at the moment (definitely need to change tyres :))

Rears 17x9 et 35 with 255/40/17 on them (slight rub on hard cornering so I'll need to roll the guards a little)

The wheel calculators say that I'll have 2.65mm from possibly touching the suspension up front so my question is... Is that enough clearance, or do I need a spacer? If so what size would you recommend? Also what size tyre would be best?

Fronts you would be best with a 215/40 Tyre
Rears would be fine.
 
If you are using/plan to use coilovers at any time you will need a 3-5mm spacer up front to clear the struts.

Thanks chase, at the moment I just have standard struts (lowered ~2 inch though) do you think 2.65mm will be enough clearance? I've got no plans for coil overs in the near future though :)

I have Enkei Racing S wheels, 17x8 (F) and 17x9 (R) +35 offset all round
I also have Federal 595 RS-Rs all corners 
fronts are 215/40/17 and fit perfectly
rears are 235/40/17 and required the guards to be rolled as they scrubbed like hell without.
255 IMO is too wide for the RS-Rs as the 235s are PERFECTLY flush with the rim.
 

Nice looking wheels there MRTurbo, I've already test fitted the rears and driven on them for a while. They only slightly scrubbed on some really hard corners and even then it was only the passanger side that I could get to rub :) I think I've got some pretty hard spring rates lol

The 2.65mm clearance to the strut is plenty. I think there's a bout 1mm clearance on mine lol.

215/40R17 17x8 +38 +32  (with a 5mm spacer)
255/40R17 17x9 +38

That looks like quite good fitment, I hope mine will sit similar to that. Thanks for the input everyone I'm going to go with 215/40r17 for front and I'll roll the rears a bit for the 255/40r17 that are fitted :)

Thanks mate i love my wheels. enjoy the rs-rs :-)

Thanks :) What does everyone think of rs-r's? I've heard they are quite grippy and very quiet, have many people here used them?
