Pre-assembled with camber plates and matching rear shocks. No spring compressor, cutting, welding or modification needed. Fabricated from 1026 DOM steel, the Ground Control strut is much stronger than the stock strut. Skip welded 0.250 flanges reduce flex while adding strength. 1 inch shorter than stock, reduced droop and Koni strut inserts specially valved by Koni of Holland for Ground Control or Koni race strut inserts are provided, depending on suitability with your spring rate. POC, PCA and SCCA legal. This package price is significantly discounted, and is intended for club racing and track days.
Made from 7075-T6 aluminum alloy, these plates offer more camber adjustment than stock, caster adjustment, aircraft bearings, engraved with calibrated degrees, and stainless steel reinforcement. Every component is anodized or plated, including fasteners. Adds extra travel to avoid excessive bottoming out, this is a very well engineered product. The stainless steel reinforcement prevents electrolysis between the steel fender and the aluminum camber plate.
Camber and caster are separately adjustable by sliding the mounts, without removing any components from the car. The priority of this design is to allow fast, repeatable alignment changes at the track.
The Ground Control camber plates feature two sets of bearings, a proprietary bearing, made to our specs by Aurora in the USA, which allows for articulation of the shock shaft. This spherical bearing is very understressed, as the Ground Control design does NOT support the weight of the car on the spherical bearing. Instead, the weight of the car is supported by a completely separate articulating needle bearing, which is also manufactured for Ground Control in the USA.
Rear Coil-over assemblies:
We start with a Ground Control designed rear lower shock mount. Machined from high carbon steel, and using a grade 8 bolt, this rear lower mount is designed to carry the weight of the car after springs are added to the shock. We utilize a Koni SINGLE ADJUSTABLE mono tube rear shock, adjustable for rebound damping. This shock is available in our standard default damping for standard width cars, or heavier damping for wider cars with higher spring rates. The Koni shock is mounted inverted for less unsprung weight, and features the exclusive GC coil-over hardware with single-locking sleeve and and your choice of Eibach race spring. The same kit is used to supplement rear torsion bars (PCA Stock Class) or by choosing a different spring rate, the rear torsion bars can be removed completely.
