THIS KIT INCLUDES THE FOLLOWING: (click items for details)
Koni Single Adjustable Front Strut - Custom Valved strut inserts are externally adjustable from underneath the hood, even with the factory strut brace. This strut is prepared for coil over use, and eliminates machining of critical suspension components.
Ground Control Threaded Sleeves - This system is designed to eliminate stress risers caused by machining notches into the strut housing. Unlike other companies that claim superiority by cutting threads into a critical component of the suspension, Ground Control uses engineering common sense to maximize the strength of the suspension.
Ground Control Adjustable Spring Perch - A unique design, that uses an allen head bolt to clamp the single threaded perch into the correct position. No secondary pieces are needed to "jam" the threaded perch into position. This method of clamping onto the threads also prevents sand, grit, and water from getting into the threads, which is a common problem with jam nuts.
Ground Control / Koni Single Adjustable Rear Shocks - Preadjusted by Ground Control to match your rear spring rates using our shock dyno. The GC custom valved version of this kit is the "top-adjust" version, which adjusts from inside the trunk or under the hood with no tools needed.
Ground Control Touring Camber / Caster Plates - These plates feature over 23mm of total camber adjustment (16mm negative/7.5mm positive), with the ability to make corrective caster changes to equalize side-to-side caster in the stock position.
Other features include replaceable waterproof German axial load bearings, and urethane bushings for long life, less deflection, and a smooth silent ride on either stock, or 2.5" racing springs.
Our camber plates are also engraved with the Ground Control logo in an arch which can be used to locate the plate in the stock position for easy, repeatable, adjustment from street to track and back.
All components are anodized or zinc plated for corrosion resistance.
We also offer our lifetime guarantee! (Bearings not included)
