Why does your 992 GT3 need upgraded suspension arms?
The 992.1 GT3 was a game changer for the Porsche community, the first production 911 to get double wishbone front suspension. The steering feels amazing. The turn-in is incredible.
But just because it's a game changer doesn't mean we can't find ways to improve it. Where we found the limitations is in the achievable alignment targets. So we built four levels of suspension setup packages, for each level of driver and how you want to set the car up.
BASIC — Front and rear shims, adjustable sway bar end links, and extended-length titanium tie rods. The factory end links aren't adjustable, so if you corner balance the car to an aggressive degree, you end up with preload in the sway bars and that makes the car's behavior inconsistent from left to right. Our end links ensure zero preload for a nice, neutral, predictable car. The shims get you additional camber, and the titanium tie rods give you the thread length to correct the toe safely plus they reduce unsprung weight and the pinch clamp makes them really easy to adjust. Everything to get you started on a more aggressive alignment, improve your tire wear, and get your sea legs for your first track day.
INTERMEDIATE — Adds one component: our upper camber link. It brings the top of the suspension farther inboard, giving you more negative camber and the option for more tire clearance if you're looking to run a slightly wider front tire. The factory eccentric bolt is a pain to adjust, so we provide eccentric lockout washers for a fixed mounting point at your upper camber target. Simple. Easy to adjust, easy to install so you can go faster on the track.
ADVANCED — Now we're getting a little more aggressive: we've widened the front track. The factory lower control arm only has so much stud length. The Dundon lower control arms feature an extended length arm, extended-length shims, high-quality studs and hardware, and a really nice spherical bearing. Widening the front track gives the front more leverage over the rear and that reduces understeer. We also address caster, an often overlooked figure but really important to balance handling and tire wear. Our front tension arm kit has an aerodynamic profile just like the 992 GT3 RS factory tension arm: set the length, dial in your caster figure, tighten it down. Front track, camber, caster, toe a really wide range of available alignment targets. Run slicks, run an aggressive wheel and tire fitment, or simply get the most life and the most grip out of your tires.
PRO — The final level. We've now replaced every arm on the car: full lower control arms, the tension arms, and a complete two-piece rear lower control arm with shims for rear camber. Then the dog bones, six total, these remove all of the rubber from the multilink rear suspension. That removes any of the lash from the rubber bushings, so the only things flexing are the dampers, the springs, and the tire. You really notice the sensitivity, control, and responsiveness. We really increase the connection between the driver and the car. And all of the bearings are easily serviceable over the long run.
