My car is complete for the most part and is a proper stage rally car. Tuthill provided wire harness, dampers, skidplates and brakes...all decent parts, but given the chance, i'd likely go a different route with some. Also, if you want more of a rally spec car, then don't do 16's as there are no gravel tires in the size, just truck stuff thats lame and not proper.
Height - Safari height offers zero advantage on semi normal conditions, and, plenty of cons on most. Real rally cars are not that high.
Tires - There are tons of rally tires available. I'm running Pirelli K series in Medium compound. Running 195/70/15 on 15x6 / 15x7
Dampers - Exe-tc gravel dampers don't have a raise spindle as real rally cars are not that high...You 100% could run the 1000 lakes damper, especially if this will be a fun only car.
