Now available in a package is the rear thrust arm kit for all three thrust arms, the two uppers and the lower as well. Each piece retains the factory mounting points for brake lines, travel sensors etc. This set upgrades your GT3 / RS factory control arms with 5-axis DMG Mori machined replacements. As a further commitment to detail, each aluminum production piece is hard-coat treated for 7-8x the wear resistance of traditional anodizing. All of the rubber within the OE wishbones are replaced with the very best Aurora spherical bearings for ultimate control and confidence at the limit.
