NEW BMW E30 , E36 , E46 SUSPENSION              COMPONENTS!

Ground Control Racing Suspension
 has added new products to our line of high-performance suspension components for the BMW 3 series chassis. We use sophisticated data acquisition systems (shown at right) to develop our street and race car suspension.  The information we collect is used to make decisions on spring rates, ride height and shock valving.  We analyze data such as lateral G and suspension movement, and more complex data from integration such as shock velocity, roll angle, and chassis movement.

New bolt-in parts can transform your stock street BMW into a track-ready, weekend racer. New pieces include Camber/Caster adjustable plates and adjustable ride height spring kits; all bolt-in for easy installation. 
 See how A Part is Born at Ground Control.

ccp-ad~1.jpg (10640 bytes)Adjustable Camber/Caster™ plates are machined from 7075 T-6 billet aluminum  and are anodized (type II pewter) for greater durability and appearance. Aircraft quality spherical and needle bearings are utilized to eliminate unwanted bushing flex as well as allowing for bind-free suspension movement. The 100% bolt-in design is an advantage if stock components need to be re-installed in the future. 

Ground Control Suspension Camber/Caster plates can give your BMW up to -3 ½° of camber. Caster is adjusted separately and independently.  Camber/Caster plates are designed to be used with 60mm, 2½ or 2 ¼ inch I.D. coil-over springs.

 These are the simply the best Camber/Caster plates available anywhere, AT ANY COST. The outer three bolts adjust camber, the four center bolts adjust caster. There is no need to use a wrench under the plate, because the bolts are in machined slots. E36 set includes stainless steel strut tower reinforcements. (move camber to CL to adjust caster)

   $ 399/pair
E36 Hybrid (Street/Track) Camber/Caster Plates $ 399/pair

Ground Control Suspension Front Coil-OverAdjustable Ride Height Spring Kits (also known as coil-over kits) are an excellent way to upgrade your BMW’s appearance and performance. All spring kits feature only the highest quality components.
Adjusters: All adjusters consist of a threaded sleeve (anodized burgundy) and adjustable spring seat (anodized gold) and are made of high strength 6061 T-3 aluminum. The threads on the adjusters are square cut which locks the adjustable spring seat in place under load. A clamping screw on the adjustable spring seat is used to secure the adjustment. Adjusters not only allow you to set the ride height of your BMW, they also allow you to set corner weights for a perfectly balanced vehicle.
Springs: These coil-over kits include street or race springs. We are pleased to announce that has chosen Ground Control Racing Suspension as the west coast distributor of their ERS (Eibach Race Springs) line of springs. With our stock of over a thousand springs, you can choose what spring rates you want or let one of our experts help in making your final decision. All spring kits exclusively feature Eibach ERS springs which are cold wound, shot peened, and powder coated to insure a top quality product. All Eibach springs carry a lifetime guarantee.

BMW endlink  M3 swaybar endlink assemblies
The highest quality available. The rod ends used for our endlink assemblies are made specifically for our kit. You can't buy these rod ends out of a catalog. We have specified to the bearing manufacturer our requirements for high angularity and preloaded Teflon liners for a long service life. If you look closely, you will see the stainless steel washers we include to make our kit a tight fit into the existing 10mm holes in the factory brackets. No other company supplies such a high quality kit. Weld-on brackets to convert 84-99 318/325 and reinforcements for 90-99 M3's available separately.                 $99, set of two

 

BMW Shifter

e30,e36 Shifter Reinforcement
The correct way to solve a longtime BMW problem, this precision machined reinforcement reduces the play in the factory shift lever. Specially suited to aftermarket short shifters that still use the stock or modified stock lever, even brand new levers have play in the rubber coupler that can cause missed shifts. There is virtually no downside to installing our clever reinforcement. There is no metal to metal contact ( just like stock). This is sold as a complete kit with all tools and directions, and can be installed from inside the car. T303 stainless steel construction. Designed for e36 , but fits many others. $29 complete kit (shifter not included)

A NOTE ABOUT ORDERING OUR PRODUCTS

ALL of our kits, components and products are assembled for YOUR car.   We do not sell universal suspension kits, every order is treated as a different car and driver combination.  This is the reason that we cannot do online sales.   When you call, you will speak with a person who is experienced in suspension and racing, and your order will be treated with the same amount of care and respect that you have for your project.   In essence, your project is our project.  We have a huge inventory of parts that we use to assemble various suspension systems, and we use our in-house machining capabilities for the custom work that is sometimes needed for a suspension system.
