HID cost 500 CND... The best money I spent ever...
Rims are 16 inchs and if I put in 17s, the tire will be very low profile and I risk bending my rims... some likes to take this risk, I don't.
As for suspension, I would really love to. Everytime I go to track and can't keep up with the civics because they got good shocks, makes me want to put down 1500 dollars for a set. But, I think I will spend this money for my next car... and I will look for nothing but power.
