Track Wheels and Tyres
Been looking at a track set up and thinking about 18" rims and tyres.
Now I have seen a few 18" running on ISF's I am a little more comfortable on running this type of set up and clearing the front calipers.
Got my eye on the following
OZ Ultraleggera's
Front 18" x 8" ET48 running 235 x 40 DOT Tyres
Rear 18" x 9" ET 55 running 265 x 40 DOT Tyres
Any thoughts or comments on this possible fit and trouble i.e. rubbing etc?
Cheers

If this is going to be "just" a track setup, then you want to get front and rear in the same size, this will do two things, first you can rotate them front to rear, second, you will help remove a lot of the under-steer (or push) that the F is prone too on the track. p.s. unless you are from Europe we spell tyres "tires" ;-)
Hope this helps

Thanks for the comments.
FYI I am in OZ so the spelling of tyres or tires is correct
The problem I see with running none stagger is the maximum tyre on the rear, fully agree with the comments about understeer but the reverse will be oversteer.
I am no expert but I think understeer would be a much safer situation than oversteer with an undersize rear end????
Will 255 fit all round?
Any comments on the actual fit and clearing calipers etc?

i also have a non staggered wheel/tire on mine for a while and it balances out the car nicely. excessive oversteer in not an issue at all, the car just does what you want instead of being a understeering disaster and aiming 3 feet inside of where the car is actually going to end up..

Camber is not adjustable from the factory. Toe out kills the inside edges of the tires and there's lots of evidence this is true in both the IS-F and 2IS forums.
Many of us have close to -1.0 degrees camber in front from the factory at stock ride height. Adding camber would help, but so would a suspension not intentionally designed to induce understeer by every suspension component.
