zag,
for a rally runner, I expect you'll have to checkout the various bushings (steering, a-arms, 3link in the rear). Dunno bout yours, but my bushings are REAL loose. It's not too bad (road manners are tolerable, and being loose on a trail isn't a bad thing). For a rally run, I'd want ZERO play in the steering, and NO play in the suspension either ...
If you find the sizes for the various pieces let us know ... I expect to replace some bushings soon in mine ...
