92 SC

With my 94 fulfilling the duties of daily-driver, I'll be free to do whatever is necessary to make my 92 perform the best that it can on the track.  It doesn't have to offer a comfortable ride, go 150,000 miles on its engine, run quietly, or take me to-and-from the track.  Without those things to worry about, this project is going to be very enjoyable.

NOTE: The majority of these parts have been installed on the 92 in a very short amount of time compared to the things I've done with my 94.  Because of this, I probably won't be able to evaluate how each part individually affected the car's performance (if, in fact, it's a part that's supposed to affect performance).

I periodically receive e-mail asking why I do not have certain parts.  The reasons are simple: there are a lot of parts out there that either do not perform as described, provide a low amount of bang for the buck, or have no positive benefits whatsoever.

This section includes ALL of the items that I have installed & tried out on my 92 SC since I first got it, and not all of them exist on the car at this time.
