the rear wheels stick out about 20mm further on each side than the front wheels do, on the s.

lets say that you are building an s with custom wheels and the body panels are not a concern, because you are getting a custom wide body kit to accomodate any size wheels that you want. what size would you get?

also i understand the importance of having staggered wheels, but what proportion do they need to be?

if you go with a 10" wheel in the back, is a 9" wheel needed in the front?

also, when upgrading thw width of thw wheel, do you expand only outward, or do you want to move inward as far as you can before suspension clearance becomes an issue?

and if so, which wheel do you want to be more inward, the front or rear, or do you want then to both go in the same distance, but the rear just stick out further?

 

in stock form a 10.5" wheel will work in the rear. in the front, up to a 9" will work, but only with an aftermarket coilover system which will (hopefully) have smaller spring coils for clearance. I wouldn't recommend going over 10" in the rear, for fear of the diff and just overall handling capabilities, but that's my take.

as for the proportions, it really depends on how you set it up and what you are setting it up for. I've seen 9 in the rear and 7.5 in the front, which is more than a 1" difference, but it works. again, it depends on how it is setup and what it is made for.

as for the rest of the offset for larger wheels if you intend on going with a widebody kit that extends the rear fenders, I'd suggest putting the rest of the meat to the outside. No need to put them on the inside.

 

think road race, and i want maximum traction

 

10.5" is just fine on the S2000. Go as wide as you can.

 

from factory, do the front and rear wheels stick in just as far under the car?

i think if you want to make the ultimate race s2000, you would want to engineer it so that the underbody aerodynamics are ideal.

with that in mind i would probably want more
wheel on the outside and cover it by the wide body fenders, than having it under the car disrupting airflow.

would you guys agree with that statement?

also the extra wheel sticking out would effectivley make the car wider and that has to improve the handling, right?

also i remember reading that on x year model viper they put wider wheels on it and it hurt braking, because there was too much tire exposed and it wasnt biting the pavement the way a thinner tire would. does that sound right?

No, I wouldn't agree. Here's why: a widebody kit will allow you to cover up those wheels, but only that. A widebody kit alone does not improve the air flow around a car one bit, it actually creates more surface area for the air to flow over. This can be good or bad, but in terms of mass and how it is generated and needed, it would be bad. You'd want to keep the tires tucked under. Disrupting the flow on the underside isn't going to happen as much as it would on the outside. And if you are concerned about the undertray, you need to seal it up, get side strakes that are far lower and a splitter that is a few inches (literally) off the ground. That would minimize the amount of airflow underneath the car. Once you minimize the airflow under the car, the airflow over the car will be far greater than that under the car, which would produce anti-lift (not downforce!) characteristics.

 

Stock wheel width on AP2's are 7 front, and 8.5 rear, making a 1.5" difference. I'd go with 8.5 wide fronts and 10 wide rears, fitting 245/275 tire combo. For the s2k's weight those are all the tires you will probably need.
