Go for the STS class. I just ran my first autox ever over the weekend in my 96 SE. I had a blast and it looks like i'm going to be pretty competitive. The only mods i've done are the KKM(That boots me out of GS) and removed the resonator. I was less than a second off of the slightly-seasoned drives of a new Celica GTS and Subaru Impreza 2.5 RS. IT was a blast. and i've heard that you only get better with more seat time... maybe i'll be able to start bringing home trophies for all the 'tours out there in the near future!
