Don't forget about skid plates!! Then there is the fuel shutoff system, fire supression system, rally computer, SFI/FIA/RA approved gear, Hans Devices, inspections, licensing, hydraulic Ebrake, lighting system for night, etc!!!! and those are just the main things not mentioned. I haven't even touched on tires, camber caster kits, body strengthining jacks/ emergency equipment, radios, cameras, etc. my list, which i have priced out for new parts is around 16k for my car, granted, i'm fabbing up alot of my own stuff and finding used parts, so i'm hoping to keep it under 10!!!!! Not trying to be a killjoy, i promise, I think more people should get into rallying!! but the reality is its pricy and takes alot of custom work!!!
Now I rive 2 7.3 L diesel trucks!
