Adjustable Caster Arms with Anti-Dive / Anti-Squat For Porsche 986 and 987 Boxster/Cayman-Free Shipping Worldwide

Our caster arms provide adjustable caster and anti-dive ability when used on the front, and adjustable wheel base,
weight distribution, and anti-squat when used on the rear. Billet aluminum CNC machined ,Finished with hard anodized .The strength is close to that of steel billet, which is 1/3 of the weight of steel billet.

Front Suspension

Threaded double-adjuster makes it easy to extend or shorten the arm.
This makes for easy caster adjustment – an important adjustment the factory left out.
A must-have for cars with GT3 style extendable style lower control arms to correct for un-intended caster increase that is caused by the extended LCAs.
Anti-dive behavior can also be adjusted. Lowering the front of the arm using the provided spacers reduces front dive under braking.
Adjustable in 2mm increments.

Rear Suspension

Adjustable Caster Arms can reduce rear overhang and rear weight bias. A must-have for cars with GT3 style extendable style lower control arms.
Adjust the length of the caster arms to correct the position of the rear wheels that have been drawn forward by aggressive camber settings.
Even over-compensate for less rear weight bias than stock.
With the heavy mass of the engine cantilevered behind the rear axle, even small changes in wheel base make significant changes in weight distribution.
Shortening the overhang reduces the famous 911 “pendulum” effect in corners.
Anti-squat behavior can also be adjusted. Raising the front of the caster arm using the provided spacers reduces rear squat under acceleration.
Adjustable in 2mm increments.
