By having these different sizes in the front and rear...would there be any significant changes to performance and wear? They both arent drastic in size, only about an inch of contact patch and a few mm on the sidewall difference, but i just want to know if there would be any drastic changes. thanks.

 

would also like to know, as i was thinking about buying some 225/50/15 DRs for the front and some cheap 195/50/50 for the rear but its mainly for straight line traction...so basic question is whats the downside to running different size in front and back?

 

your camber and caster will change slightly just have it aligned checked at a shop after your install but camber and caster will change for sure

 

its never a good ideal to have different tire sizes on a car. By having smaller tires in the back you will have less traction in the rear which is usually also it will have weird handling trust me I know I had that exact setup and I wanted to end myself. Also it looked really weird. Unless you are just planning on doing drag with it its fine but to drive around never.
