Does 18" make your car look that much better, or should i just invest in 19"..And if i do get 19"s will i have any problems turning, scratching the tire, etc.,

 

IMO 18's don't look that much bigger then stock tl-s 17 inch rims. I would go 19 inch. As long as you get the proper size rim, tire and offset you shouldn't rub. MAX rim size = 19x7.5 w/ 235 35 r 19 rubbers with an offset of +50 to +52. that would be the ideal 19 inch setup for our cars. from personal experience, i have that setup and lowered and dont rub at all even w/ 5 people in the car. Speedo stays the same too because overall diameter is the same.

 

If you are going to get 18" MOMOs, get +42 offset. Here is a picture of mine:

 

:wow:
That rim looks really nice~~~

 

This works ok! !8s are good too!

 

Personally I would do 18s. There is less chance of rubbing, you may not have to roll your fenders, they are less expensive, you can go with a higher series of tire for less chance of rim damage, lighter weight (depends on what brand/type of rim you get) and so on. Ultimately it is just preference. Speed and performance or looks and pimpedness?
