How to build independent rear suspension final assembly installation.
Modified live solid axle (4 link suspension) with watts link on Protlum coilovers is upgraded to IRS (independent rear suspension double A arms). On this video you can se how we have build rear subframe which is holding BMW e36 188mm differential from Racing diffs with LSD (limited slip differential). All subframe parts and suspension parts like a-arms, tie correction rods, are made from 4130 (25CrMo4) chromoly, knuckles or uprights are made from high grade (6082 T6) aluminum. Bump steer is minimized and roll center height can easily be changed as well as all other parameters like camber, castor, toe and anti squat. On rear end we do not use polyurethane bushes, all free moving joints are motorsport uniballs for better stability.

CAR:
Lada VFTS prototype
ENGINE Model: Fiat 2l twincam 8 valve engine(Ritmo 130 TC abarth).

Our budget is limited so we need to design, test and produce rally car parts on our own. Unfortunately, we cannot manufacture everything so your help would be greatly appreciated.
