hey,
i wouldnt recomend getting anythign bigger than 15's. i recently fitted 18's with Toyo proxy ultra low profile tyres. and it effects economy horribly, id recomend some team dynamics 15's as their lightweight and u can lower your ride with 15's.
hi,
i have the same K&N induction kit, and it makes a slight noise when u first touch the acceleration but its not very loud when actually driving. the best cheap mods i have found is replacing the wheels and tearing out the back. if you want everyone to look then get a full through de-cat...
