I already have one. I got it even before I picked up the car. Thats how desperate I was to start buying stuff for my new Z.
The Aluminium Tax disc holder is a must too for any hardcore tuner.
I dropped 2 grams in weight from the stock tax disc holder and could feel the extra throttle response instantly.
Weight reduction is the key to fast cars.
My next mod to make the car lighter, will be to attach some childrens ballons full of helium to my wing mirrors.
In fact, I think the best way to lighten your Z for the track is just not have a driver in it. If you dont get in, then your 75-90 kg saving could give your car the extra edge in a race.
Unfortunately, the telekinesis skills to change gear AND steer at the same time, are beyond me.
I'll just have to keep practising!
Explains a lot, will see how Sarnie an mine research project turns out. must resist
