AutoX is awesome! Its so much fun. I cant wait to go again now with front and rear strut braces, subframe connectors, and the Koni kit. Not to mention stickier tires. Its going to be a blast!
I dont go to compete, however. I go to have fun and hang out with fellow car enthusiasts. Talk about cars, learn about new stuff, etc. With all the mods on my car I get stuck in a class that I couldnt be competitive in even if I tried, so I couldnt really give a crap about that.
The first time I did it I did have serious thoughts about selling my SVT and buying a miata or some other small [cheap] RWD car. There was a S/C Miata the last time I went, and that thing looking like a farkin blast to drive. You could build up an old one for a reasonable amount too.
