    hi guys! i have civic coupe ex-l, stock rims are 16inches and im planning to upgrade to 17 or 18. do you know the consequences of increasing rim size? or any negative effects to the car? thanks! and how about those sensors? i really dont have any idea what it is all about.
  2. Si Only
    With my older Civic, i found Spoon Sports and T1R to be my top favorites for performance. I used some Injen parts in the past, but i ended up selling them within weeks of buying it. What are your favorite aftermarket performance brands?
