I have Gramlight 57s on front

and Volk TE37 on rear.

do U guys think it matters except looking?

can affect differential or something like that?

 

what are the specs of the rims and tires? pics?

 

why do you have 2 different styles? lol

it shouldnt matter if you have the same size. but im guessing they weigh differently. you're front/rear weight ratio will be off. say your rear rims are heavier...i guess its similar to driving with more weight in your trunnk.

 

As long as the tire diameter is the same it won't hurt anything.
A few people I have known have different wheel sizes on their EVOs with no problem.

 

you should put the same wheel on the same side so it doesn't look odd
