TECHNICAL DESCRIPTION
The factory lower inner control arm (LCA) has mounting studs that are too short to achieve a “good” performance alignment. Dundon's extended-length LCA's add not only track width, but stud length, to safely increase negative camber without running out of threads.
Two different lengths to choose from depending how much camber you want. Stock 992 GT3RS maxes out at about ~2.8° of camber (depending on ride height) and you can only add 5mm of shim on the stock arms.
- Stock GT3RS length arms with extended studs - Allows for 10-12mm of shims (Approx. 0.5° more camber range over stock)
- GT3RS +5mm length arms with extended studs - Approx. 1.0° more camber range over stock (these are the ones you want for track work)
Studs are grade 10.9 with rolled threads, includes 12-point ARP nuts, and high-grade FK bearings.
