  1. A buddy of mine just bought one of these about a week ago and he is already wanting to modify it. He plans to take it on autocross courses so I know he’ll be changing up the suspension. I’ll have to show him this guide since it is very well written out and the pictures help a lot. However, I know it’ll take us a bit longer since we don’t have a big car jack like you do.
