DITTO!
It's halarious to read how some people need to "upgrade" their Porsche. Even a stock C2 has a higher performance envelope than most drivers can match.
Having said that there are some options that will enhance the driving experience, especially at the track. I would suggest an exhaust change to hear your engine, the stock exhaust is waay too quiet at the track with a helmet and loud traffic. Next, if the car doesn't have a sports suspension and you want it lowered to the intended ride height, get the RoW 030, or X73/4. Always stick to the factor suspension stuff unless you are actually racing the car. A Porsche short shifter can make driving more fun, gear engagement is more solid. These can be bought in the $300 range online/ebay from dealers, at this $ delta it makes no sense to use an aftermarket piece even if it is the same. But there is nothing wrong with the stock plastic shifter, they use it in the factory race cars.

 

Then get a GHL exhaust, they offer a special on Rennlist.com. Dirt cheap, something like $700 without tips. It's a great exhaust and a great price. You will not find PSE for less than $1400.
