Basically... - K&N panel filter, remove resonator in front bar and re-route new piping front hole in front bar to air box. Sure will breath better and little more noise. - In my sedan I've got King Lows and KYB Excel G twin tube shocks. Quite stiff in front that's for sure. Rear is ok. Front with lows on 14s is quite low already. I scrap over quite a few car park speed bumps as is (that is without mud flaps). - For standard looks can get an AE101 or AE111 Toyota Levin Genuine 3 point front strut brace or more effective would be Whiteline 2 point strut brace. - I recommend 2" exhaust, high flow cat and make sure you get a good muffler (Lukey is good) not a cheap crappy straight through
