On converting an MX6 to a rally car - Tarmac rallies i can imagine it'd be a lot of fun and in that case just look at peirs's car - track and tarmac rally isnt a huuuuuge difference in major set up points - just lots of minor changes.
Dont bother trying to get it into a dirt rally though unless youve got a lot of cash to replace things that break. We dont have strong enough cars to cope with dirt rally.
My MX6 is a daily driven track (ish) car - I'm about to start the weight reduction game as I'm going to move up a class cause its slower than the class I'm in at the moment...
Daily - '92 2G -- White, KLZE, Selex coilovers, full black leather interior, CAI, pacesetters, exhaust 16x8 BBS RS (replicas)
