He didnt use any parts from their old stuff & no parts from any production cars. Frankly, the geometry in those clips & frames is very close to our TA, AXT & AX Warrior racing front suspensions. The grip & turning ability on track are close as well. Ron liked the ATS Tall Spindlebut it needed improvementsso he relocated the LBJ pad downward. Then started from scratch on the steering arm, dropping & twisting the steering arm outward for a LOT more Ackerman, which is key to grip on the inside front tire.o8 KPI AngleoGenuine SKF C7 Corvette Heavy Duty Hub/Bearing AssemblyAsk Ron AboutoX-Tracker TechnologyHub Upgrade oRated at 1280# & 1515# Options o5 x 4.75 Wheel Pattern oFixed Length 4.75 Long Steering ArmoNew ARP 1/2"-20 Long Wheel Studs Included, but Not InstalledHowe Ball Joints with Zero Stiction: oStiction Takes Force to Get Something Unstuck Before it Moves.
