alamak! Herbie taiko, please don't put me so high on top of klcc tower, i m oni a newbie nia
mayb get a more powerful car will serve the purpose n intention
my suggestion:
-change your rollstock to better n lighter one like Work Emotion or Te37
-get a better rubber for reducing rolling resistant like yokohama ad07
-change your exhuast system to performance type maybe u can go to speedwork
-try add-in a plug-in ecu like motec to optimize your current engine
-maybe u should upgrade to high cam to get the monster hiding in the hood
-chuck out the heavy stuff in your car whatever which is not needed
-change the filter to CAI/Cold Air Intake which is better than those 2 things that u are thinking to get
-add a Gt wing to your car to get better downforce and stablity, and get one of those evo defuser also if they can fit in
-try the engine treatment also X1r,u will have better high rev and smoother power(RM63) in Jusco u can get
-get the car a adjustable abs n lowered it kau kau, handling n performance wise will have a new improvement
-the list goes on.................................if u stil not satisfied, u can always take Herbie car for a free ride i m sure he is happy to loan you for a year or two
