275 is a mild stretch in 10.5". I dont mind it though and i hate stretched tires. i was only able to tell when my rim lip hit before tire sidewall lol.

Thanks for the advice guys. More options always great!

I personally love RE-11 but I believe RS3 are stickier when hot but does not provide good wet like RE-11s. Plus RE-11 for 18" don't come in 285, vise-versa RS3 doesn't come in 285 for 19".

I'll target for:
Hankook R-S3: 285/40 or 285/35 Square setup
Spacers: 10mm Front / 25mm or 30mm Rear
Wheels: 18x10.5" width all around with proper offset...

a mild stretch actually quickens the tire's ability to produce grip under cornering load, since the contact patch doesnt actually grip until the sidewall is in tension, so running a mild stretch "pre loads" the sidewall making for faster response, so in turn faster lap times.

when you run a tire too wide for the rim width, not only is that grip response slowed, but their is also more contact patch deformation while cornering.



285/35/18 on 18x10.5 all around is the ticket. Martin and i will be running RS3s in those same sizes soon. im also getting NT03s as my track wheels soon also

in the front et30 is the safe limit inward, and what i run et28 is in my opinion the safe limit outward with a 285/35/18 tire and -3 camber. no rubbing on anything what so ever, you might be able to run more aggresive offset, but i havent tested that so i cant say for sure. Just i know under track conditions, those offsets are proven in front

I have decided to go with a new set of 18" track dedicated wheels.
I would prefer to have 18x10 in front and 18x10.5 in rear but most wheels only have either 9.5 or 10.5 for 18".

So I will go with 18x10.5 all around as my main goal is to be able to run a true square setup.

Clint, I saw your previous setup with:
F:18x9.5 +35 (20mm Spacer) - Offset=15mm; Camber: -3 Degrees
R:18x10.5 +15 (No Spacer) - Offset=15mm; Camber: -2 Degrees

If I were to go with the Enkei PF01, would you recommend the following?
F: 18x10.5 +38 (20mm Spacer) - Offset=18mm; Camber: -2.9 Degrees
R:18x10.5 +15 (No Spacer) - Offset=15mm; Camber: -1.8 Degrees

Will this clear the front brakes or not rub? Any help would be great.

Do you know of any 18x10.5 wheel setup that doesn't require spacers?
i.e. can I go with the following w/ same wheels all around? Will this clear the front brakes?
F: 18x10.5 +15 (No Spacer) - Offset=15mm; Camber: -2.9 Degrees
R:18x10.5 +15 (No Spacer) - Offset=15mm; Camber: -1.8 Degrees

I would go the spacer routine, then you can rotate front to back.

yup, thanks to Clint for doing the hw for me! Scuffydog, just remember if you slam ur car, the tires will rub some of the fender liners.... I doubt anyone is running as low as me at the moment but I will need to raise the car, realign and recorner balance its just too low! I shoot sparks at the track and street!!
