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.

Dramatically improve performance and aesthetics with an average lowering up to 1.4" front and rear.
Take your F3x to the next level with upgraded performance and aesthetic. ECS lowering springs are specifically designed with both handling and comfort in mind for the best mix or performance and drivability. With an average lowering range of 1.0"-1.4" you have the added benefit of lower center of gravity providing superior cornering and better steering feedback. Lowering springs not only increase handling performance they provide an astounding aesthetic upgrade by decreasing the wheel gap and giving your car a more planted/fitted appearance.
FEATURES AND DESIGN:
MADE IN THE USA
Average lowering of 1.0" to 1.4"
Front spring rate: 184 lbs/in
Rear spring rate: 462 lbs/in
Lowered center of gravity
Linear style springs
Black powder coating with red ECS logo
Designed specifically for your chassis these F3x lowering springs feature a linear style spring similar to a coilover. The issue with coilovers is the rough ride due to a drastic drop and much higher spring rates. When you have higher spring rate like coilovers it takes much more force to compress the spring which leads to a much more rigid ride. ECS lowering springs provide a happy medium between the factory suspension and coilover suspension. These springs are stiffer than factory but softer than a coilover spring to achieve the balance of increased performance and aesthetics while retaining a comfortable ride.
What is spring rate?
You may ask yourself "what is the spring rate and how does it affect my ride?" Spring rate is the amount of force needed to compress a spring one inch. For example if you have a spring rate of 300lbs per inch it will take 300lbs of force to compress the spring one inch. An average coilover for your F3x has over 400 lbs/in for the front and over 500 lbs/in for the rear, this means that it will take over 400lbs of force to compress your front spring one inch and over 500lbs of force to compress the rear one inch. The higher the spring rate, the more rigid your ride is going to be. ECS lowering springs for your F3x have a spring rate of 184 lbs/in in the front and 462 lbs/in, an increase over factory but much less than a coilover. You can now both understand and explain the benefits of lowering springs to find the best solution for you.

The SPL BMW F2X/F3X Front Lower Control Arms (FLCA) provide roll center, camber, and track width adjustment for the rear wheel drive (RWD) F2X/F3X BMWs while eliminating bushing deflection resulting in sharpened steering response and driving precision.
Negative Camber Benefits
The ability to run more negative camber greatly improves the peak lateral grip available. Adding negative camber results in the tire having an optimal contact patch as the body rolls due to cornering forces. This is especially important with better tires and a must-have for anyone looking to prevent excessive outer shoulder wear (and heating) on their tires due to a lack of camber.
Wider Front Track Width Benefits
Further handling improvements can be had by increasing the front track width from the factory 60.5" (F3X) or 59.9" (F2X) to be closer to the M3's 62.2". If you applied the M3's width to the M340i it would reduce the outer front tire loading by roughly 20 lbs and apply it to the inner front tire. The result would be greater peak grip (~0.04G), improved stability, and faster lap times.
Roll Center Correction Benefits
Lowering the F2X/F3X results in a greater distance between the front roll center and the center of gravity. This acts like a longer lever, creating more body roll, bumpsteer, and requiring additional static camber angle to maintain the same handling. The SPL front lower control arms allow the roll center to be corrected for a wide range of ride heights to improve handling and stability.
The lower control arms come with a ride height sensor bracket to maintain the factory ride height sensor location, regardless of length of the arm to keep those finicky BMW chassis electronics happy.
Benefits
Adjustable Camber, Roll Center, and Track Width
Eliminates Bushing Deflection
Improved Tire Life with Ideal Camber Settings
Lightweight, High-Strength Construction
Stackable 304SS Roll Center Spacers in 1/8" and 1/4" Sizes
US Made, PTFE Lined FK Rod Ends
Materials
6061-T6 aluminum black anodized arm, clamps, and spacers
4130 CrMo electroless nickel-plated double adjuster
Ti6Al4V titanium socket head cap screws
304 stainless steel roll center and knuckle spacers
5/8" 4140 CrMo stud
FK PTFE-lined spherical bearings (F1 spec, self-cleaning)
Suitable for all uses, from daily driver to race car.

Looking for upgraded lower control arms that don't limit adjustment capabilities like the OE control arms? These Turner Performance Lower Control Arms may be exactly what you need! These CNC'd billet aluminum control arms allow you to adjust roll center, camber, and track width easily and lock in your adjustments securely.
The construction of these control arms allows for significant weight savings, reducing unsprung weight, while maintaining high levels of strength that is up to track use and abuse. Instead of using traditional jam nuts, these Turner Control Arms utilize a pinch bolt and rotating clamp design that allows high clamping forces to lock in track width and camper specifications without making it difficult to keep bearings properly aligned. Stainless steel spacers are included to enable roll center correction for lowered vehicles. To further improve control arm operation over the OE design, these control arms use FK rod ends and high misalignment solid spherical bushings to get rid of binding and flex.
Features:
Lightweight Aluminum, Titanium, Chromoly and Stainless Steel construction
Correct ball joint angle for full articulation
Clamp design allows for easy access to lock down your alignment settings
Low friction 3-piece Teflon lined FK spherical bushings and Heim joints/rod ends
Multiple size stainless steel roll center spacers for precise adjustment
