Peter @ Wheel Experts is also very, very knowledgable...don't leave him out!

No in addition to what Will said...

On the rear, you can also do a 19" or 20" x 10" with a +42 offset. I haven't pushed the limits on a 10" wide setup but I know a +42 will work and depending on the tire, you can probably push it out a little more (like +40). Also, depending on the wheel design, you can go down to +47 if need be.

On the front, you can also do a 19" or 20" x 9". Again, +42 or so should be good....I wouldn't go much deeper than that...you'll start getting too close to the suspension upright...

And don't forget about brake clearance if you have a big brake kit (well, except for the Wilwood 6-piston setup I'm working on which will have the same caliper clearance needs as the stock caliper.) For those, you'll need a high disk setup...I recommend using a 8.5" wide wheel with a +38 just to be safe...

If you want a comfortable ride and some extra rim protection, the 19" Fat setup is the way to go...ask Cerberus about it...he has that exact setup (and someone else with a GS has it too...I can't remember his name). I'm also going to do this on my SC400.

For that setup, a 19x10 rear is perfect if you're going to use a meaty tire like the S-03...Which, BTW, with the fat setup, you're rather limited to your tire choices but the S-03 is available and that's the tire I'd run anyways...Pirelli is your other choice...but personally, I think Pirelli's SUCK.

Front Wheel - 19x8.5 (+38 to +45) or 19x9 (+42)
Front Tire - 245/40-19

Rear Wheel - 19x10 (+42 to +47)
Rear Tire - 275/35-19

It's best to pick out a wheel and then look to see what's available. If you pick a decent wheel from decent company, chances are they will have a decent setup for your car.

I need to get a def answer... I ordered new rims and i'm screwed if my tires rub. My rim size is 19x9.5 and the offset for the rim is 36. I've tried looking for a post on this but i couldn't find any. My suspension is stock. Help me out guys. THanks
