yea, the tires would be the first thing to go, then to eibach or
comptech sport springs. a rear swaybar upgrade is very important as it will make it corner better under all situations and be more planted. shocks are very good on this car. steering will improve with the rear axle being stiffened. rideheight need only be reduced by 1.75 or 2" this is accomplished by the comptech or eibach springs.

power: leave stock intake tract, upgrade the filter and route cold air to the box. wait for a comptech icebox CAI.
comptech header, and catback will round this out nicely

stock brakes are very adequate for upgrades, the car will ride great and make about 185/135 on the wheels. it is really hurting
for some powerband adjustment down low... before 5K it is pretty dull. drive her hard and then replace the clutch with something proven from the aftermarket. the stock clutch is easy to incinerate in this car. having close ties to an acura store, I see the photos of the damaged parts and the clutches are a pretty sight when the pins in the disks are warn to the nub...

hehe... yes it is a bubble car.... we cant really fix that the OEM
body kit on the Type_S does make an improvement. by the way,
you can have comptech stuff installed when you buy the car and put on your deal.

something to think about...

your GSR wont last forever (unfortunately...)
