GROUND CONTROL FULL COILOVER KIT E30 & M3, DOUBLE ADJUSTABLE
Ref: 2020.82
THESE KITS ARE CUSTOM BUILT TO ORDER, PLEASE LET US KNOW THE EXACT MODEL AND USAGE OF YOUR VEHICLE, INCLUDING ANY TRACK USE ETC.
THIS KIT INCLUDES THE FOLLOWING:
-2 GROUND CONTROL / Koni double adjustable strut inserts, bolted into existing housings.
Koni Double 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.
-2 KONI double adjustable rear shocks
Ground Control / Koni Double 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.
-1 PAIR front Camber Plates.
Ground Control Racing Camber / Caster Plates - More camber adjustment than stock, caster adjustment, aircraft bearings, and engraved with calibrated degrees. Every component is anodized or plated, including fasteners. Adds extra travel to avoid excessive bottoming out, this is a very well engineered product.
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.
-4 EIBACH ERS Springs, or Ground Control springs by Eibach. (your choice)
Eibach Springs - Any spring rate is available. Eibach springs are made on German machines both in the USA and in Germany, however all Eibach springs have a lifetime guarantee against sagging, rate change, or any manufacturing or material failure. Lifetime guarantee. Compare!
-4 GROUND CONTROL bump stops (made in Germany)
Ground Control Bump Stops - We do not just ask you to reuse your stock bump. The stock bump stop is designed for stock suspension we provide a bump stop designed to work with our suspension. These are soft foam, same quality as OE BMW parts, but made to our specs in Germany.
-2 REAR ride height adjusters and upper perches.
Ground Control Rear Ride Height Adjustment Kit - Billet aluminum threaded adjusters press onto the top of the rear control arm.
-1 PAIR rear upper shock mounts (urethane)
Ground Control Rear Shock Mount - Billet aluminum, urethane bushings, pre-assembled. Includes gaskets and reinforcements.
* Suspension is shipped completely assembled and preadjusted * (You install into your housings, or Ground Control can shorten, reinforce sway bar mount, install perches and powder coat your struts for£200.00 GBP per pair)
OPTIONS AVAILABLE :
Spring Perches - Please select from the following choices:
A = If you plan to leave the front perch alone. (limited adjustment)
OR
B = If you would like to cut the perch off and weld on a new smaller steel perch.
Front Strut Housings- Please select from the following choices:
1 = If you would like to keep standard length housings.
OR
2 = If you would like instructions on how to shorten your strut housings.
OR
3 = If you would like to send us your strut housings to weld.
