The rear lower control arms on E82/E9X models are the weakest link in the rear suspension. The arm is made from folded sheetmetal and it bends and deforms easily. Not only will it deform from potholes and curbs, tow truck drivers love to hook onto them without realizing how weak they are. We have seen other race teams complete the box section to make them stronger. A bent arm will throw off the geometry in the suspension, potentially affecting handling and tire wear. These aluminum arms are both lighter and stronger than the factory sheetmetal arms and is the best solution for chronic bending of the stock arm. These are a direct replacement to your stock arms with no changes needed to your alignment. New high-grade hardware is included.
Note: the stock arm is designed from the factory to be intentionally weak. These arms will bend so that something else in the suspension does not break. Our race cars used the stock sheetmetal arm but we replaced them often. We found that it was better to finish a race with a bent arm than not finish due to a catastrophic failure. The ECS arms are still designed to be the weakest link but are far stronger than the factory arm and will not bend as easily.

Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.
The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.
Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.
Kit Includes:
(2) Rear damping adjuster extension cables
Installation hardware and Allen key
A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.
Dinan spring specs -
Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.
For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 2 points towards your Dinan badge (Ride Quality Kit is worth 1 point).
