The z32 uprights are aluminum and are lighter than the stock S13 parts. Less unsprung is good.
In order to drive on the track with chin motorsports, the car must be in good working order and you will need a helmet. If you have no track time you will need an instructor for the first few events. Total amount you pay to chin is 375.00. 275.00 for the track time, 50.00 for the membership and 50.00 for an instructor.
Here are some more pictures.
Also, I just want to say thanks to Ivan at Central Florida Performance. He put a lot of his personal time into this car and was a tremendous help.
