If you're experiencing hard starting, flaky charging, or other electrical issues, your engine ground strap may be the culprit. On E9X BMWs, the engine ground strap is a thin, non-insulated cable that spans from the left engine mount arm to the frame horn. Despite the seemingly simple nature of this part, on older cars, it is known to cause massive headaches. Due to its non-insulated design, years of exposure to water, dirt, and road salt will cause the wire to corrode, ultimately leading to complete failure. A break in this cable will cause an open circuit, resulting in issues with the vehicle's electrical system and potentially leading to a no-start condition.

To solve this issue, ECS has engineered an exact-fit, upgraded ground strap for your E9X BMW! Unlike its OEM counterpart, this design features insulated, large-gauge copper wire for dependable conductivity and long-lasting durability. Additionally, factory-style lugs are zinc-coated, crimped, and soldered, ensuring protection against corrosion and oxidation.

Whether you're replacing a visibly corroded strap or proactively preventing failure, this solution from ECS is sure to provide lasting performance and protection.

Drastically improve the looks of your vehicle while improving your vehicle's handling characteristics and/or easily adjust your wheel fitment to allow for the proper clearance when installing parts such as new wheels, big brake kits, or lowering suspension components.Interference from components such as shocks, springs, or control arms are a common issue when installing wheel that are not a direct OE size replacement. By moving your wheels a few millimeters each, you can give yourself enough clearance for proper wheel fitment and give your car a wider stance in the process.

ECS Tuning wheel spacers are constructed of high quality 6061-T6 aircraft grade aluminum and are specifically designed by in-house engineers and cnc machined to exact standards, ensuring the best fitment possible. By carefully measuring the OEM wheel hubs and bore dimensions, these spacers mount with minimal clearance to prevent any vibration, retaining the stock-like vibration free operation. 

This kit includes wheel bolts that are lab tested to meet or exceed ISO 898 class 10.9 mechanical and physical properties to ensure perfect fastening of the wheel to the hub with no issues or potential to snap under aggressive driving conditions.

ECS Tuning is a performance and genuine parts provider that designs their ECS Tuning branded aftermarket automotive parts in-house to ensure the highest quality and affordability possible. Every part's design is subjected to a rigorous test fit and stress test period to guarantee proper fitment and continued reliability for years to come.

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.

Introducing Turner Motorsport's solution - a direct-fit, high-strength Teflon bushing. Meticulously crafted from pure Teflon rod, free from any impurities or fillers, these bushings promise extended durability. By eliminating side-to-side play in the shifter rod, they notably enhance the performance of even the stock shifter.

Elevate your BMW's shifting experience with Turner Motorsport's precision-designed replacement kit.

The combination of N52 and muffler delete surpasses all sound expectations from a small 1 series! Impressive direct-fit solution. With this new muffler/res delete you can completely transform the sound and driving experience of your 128. A simple installation that can be completed with hand tools gives you the ability to take your car to the next level at home in your garage! What sounds better than an in-line six-cylinder paired with a race-inspired exhaust setup, the answer is nothing. You have a nimble chassis fitted with an engine that provides more than enough power for spirited street driving or even taking to the track, if the exhaust is still factory you do not know what you are missing out on.

The ECS N52 Muffler & Resonator Delete removes the heavy, restrictive factory muffler and replaces it with a lighter weight, high flow, T304 stainless steel 3.0" exhaust tubing. This exhaust adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. This upgrade creates a noticeable increase in exhaust sound, without adding significant drone at cruising speeds. As an added bonus, the ECS muffler delete shaves off about 16 lbs, weighing in at only 22 lbs. OEM units out of the 128 weigh in at around 38lb, a difference you will fully notice when upgrading your exhaust.
