You can have your cake and eat it too!



I am planning on purchasing TEIN's flex system. It offers 16 point adjustability and with the optional controller you can adjust settings 32 different ways from inside the car. Ill have a smooth ride to the track and can stiffen it for the corners or let em out for the strip. (all from in the car) [/quote]

The problem here is, TEIN doesn't build their c.overs for DRAG racing. You will more then likely have more grip over a stock setup, but it's still a multi-purpose coil over, valved to handle different situation's.



Whereas the HKS DRAG unit, is purpose built for one thing.

 

It sounds to me like he might want the best of both worlds. I think that is a hell of a setup for track, street, and strip.

 

Why would you want your cake if you cant eat it??



I want the hks but they are too expensive!!!

 

One of the car magazines tested tire pressures in a street tire. Results showed that letting air pressure out of a street tire had a neglibible effect on times and would sometimes hurt performance.



Final drive is usually what the rear end gears are referred to as. Ring and pinion are both replaced.

 

Just change the shocks for different purposes. (I know it's hard, but still, right tool for the job)
