you may want to try the suspension, wheel and tire section. It will depend on what camber and flushness you want to run too.

For a stock body...

9" front will require MAX of +25 to clear coilovers...I'd run +15, and you'll be able to use 245 width tires easily...255's as a max.

For the rear...to match a 9", +15 front wheel...you'd need a +28 on a 10" wide wheel. That will require a couple degrees of camber a fender roll (no pull)...pretty simple to fit.

FWIW, on my S14 - I run 17X9, +25 on all 4 with Tein HE...235 front tire, 255 rear...fits fine. I used to run 245/40-17s on all 4, so you know you can use 245s up front, especially if you order with less offset than my wheels.

Here's a thread I came across on Zilvia...he's running 18X9, +20 and 18X10, +20...but with a weak tire combo (225 F, 245 R).

There's a good shot of the rear clearance on his car with the skinny 245 rears...that partially illustrates why I reccomended a +28 (to fit more tire).

BTW, CCW are great wheels...I have numerous friends with Supras running those. Love 'em.
