Now you can go offroad in a luxury sedan like Wendover!
-Full-time 4WD transfercase with locking center differential;
-Part-time 4WD transfercase with constant FWD and switchable RWD (as the car is initially designed for FWD);
-Locking front & rear diffs;
-Semi-auto gearbox (aka race automatic, technically automatic transmission with manual shifting);
-Low stall torque converter (experimental);
-Offroad front coilovers and rear leaf spring (which are pretty much the same as original rally ones, but like 5cm/2" higher);
-Colorable camouflage skin;
-Two configs with different drive types
NOTE: For a part-time config disconnecting rear driveshaft is a separate part which is child to rear differential in parts tree (refer to my example config). For full-time it is recommended to use the original driveshaft unless you are into weird experiments
Also, don't expect it to be much of a crawler due to it's long wheelbase and still relatively low suspension, but it goes through mud and climbs hills pretty good.
P.S. waiting for your feedback
