I am thinking about moving to 18" wheels. Many people have said that it takes away from the performance of the s2, can anyone tell me any specifics that I should be concerned with?

Thanks!

 

Only 3 things.

You are increasing unsprung weight, hence you are going to affect how quick the car is etc. 18's are mostly for looks unless you get a fatter set of rims to put more meat on the ground. Just keep your stagger if you plan on doing any spirited driving.

 

^^^ spirited driving haha i like that one

 

I think the Volk 18's are in the same rage as the OEM wheels so the weight wont hurt it so.

So the weight is the only issue?

 

^^ it's not just how heavy the wheel is. It's where the weight in the wheel is distributed. On a larger diameter wheel the weight is gonna be further away from the center which gives you a higher rotational mass. All this really means is your engine has to work harger to get those wheels spinning.

oh, and don't forget weight!

 

This is just off the line right? Would it matter at a rolling start? And does it change it THAT much?

 

Why would traction change if I were to keep the widths the same?
