BMW Coilovers for BMW E46 M3 S54 (1999-2005)

Clear BMW chassis

Coilovers provide more adjustability than a strut and spring setup and can serve a variety of different needs - it's important to be sure of what your suspension goals are. We have broken down our coilover catalog into street and track categories, this is not to say you can't use one of our aEURoestreetaEUR coilovers on the track, or vice versa, but it is to give you a starting point. Are you someone who is interested in getting your BMW lower than factory height for the aesthetic value and handling benefits in a daily driver? Check out our street category. The majority of these are priced to avoid breaking the bank, but providing a good value in terms of features and benefits. On the other hand, if you are putting together your vehicle with the track as its main purpose, take a look at our track coilovers category. We have hand selected these coilover brands as being more expensive coilovers built to hold up to abuse.

Our own custom Coil-Over suspension kit for the E46 M3 has been designed specifically for the committed motorsport enthusiast who is willing to relinquish ride comfort on the street in return for razor-sharp handling performance.

Such a combination of handling performance and quality simply cannot be matched at this special low introductory price.

This kit consists of the following
� Turner TrackSport Coil-over suspension - (front and rear H&R/Bilstein fixed-valving dampeners matched to Turner customized H&R coil springs, and feature fully-threaded front shock bodies (not an imitation sleeve-over) and adjustable rear spring perches that allow you to precisely dial in front and rear ride height.

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.
