I caught the DSM modding illness soon after buying this car back in 1997.
Thanks to some great people in Club DSM, I learned a lot about working on cars and had fun making this into one of the small handful of GS-T Spyders to run 12s without converting to all wheel drive.

The modding bug really never goes away, but I decided to resist the temptation to install a bigger turbo and go for 11s. This Spyder is fun to drive on the street and reliable, so why fix something that isn't broken?
