ECS Exact-Fit stainless reinforced brake lines ensure consistent and reliable stopping power - ECS's stainless steel lines help maintain consistent brake pressure, while capitalizing on the inherent benefits of stainless steel. If you are already planning on replacing your factory lines due to your vehicle's age, ECS's stainless steel brake lines are a great solution. Factory rubber lines expand under heavy braking, even when new. This causes sloppy pedal feel and overall poor performance. ECS reinforces their exact fit lines with braided stainless steel mesh, creating expansion resistance - this enhances pedal feel and improves performance. Their red polymer coating provides protection from the elements and abrasion that commonly affect brake lines. ECS Exact-Fit stainless lines are manufactured to comply with DOT (U.S. Department of Transportation) FMVSS 106 standards. All lines are made on dedicated, DOT-compliant brake equipment, with every line being tested to 3000 psi prior to shipment.

From years of European automotive experience, the enthusiasts at ECS Tuning have developed a strong understanding of what it takes to produce a quality high-performance brake pad. After thousands of miles and many different pad compounds, they've landed on the ideal blend for the new EP24 "Enthusiast Performance" brake pad! If you're looking for a streetable, track-capable, performance brake pad, look no further than the ECS EP24!

Features & Benefits:

Strong stopping power - Increased coefficient of friction offers satisfying stopping power when cold (a necessity for a street pad!) and even more G-force-inducing power when they warm up. With cold and warm friction comparable to Hawk HPS (and higher than many other street pads) the stopping experience with the EP24 pad is impressive for street-driven vehicles on streetable tires. Positive initial bite - Race pads have the reputation of acting like an on/off switch, which is a no-go for a pad for a street application. The EP24 offers OE-level initial bite for low-stress braking in stop-and-go situations. Reasonable dust - Race pads utilize a high metallic composition. Pads that use high amounts of metal not only dust terribly, but also will bake onto wheels with high temperatures and are a bear to clean. This is not the case with these performance street pads. Now using these pads on most of our shop cars, we’ve found over time that dust is comparable to factory pads in most applications (with greatly improved braking performance). Quiet braking - It’s not a race pad, so it shouldn’t squeal like one. While not as quiet as our ceramic DD23 pad, you’ll still be able to drive your spouse to dinner. Long life - This should be an obvious one. Even in a performance pad, your daily driver pads should last and last, so that was key in selecting our ideal compound. This compound wears slower and is kinder to rotors than two of the top competitors.

EP24 "Enthusiast Performance" brake pads are included in our Lifetime Replacement Program for worry-free motoring.

Unsure of what size spacer will work best for you? This professional kit includes 1mm, 2.5mm, 5mm, 10mm, and 15mm spacers with wheel studs and nuts for you play with. These are not the same spacers that we sell and they cannot be used to drive on. But with the studs installed the car can be lowered to the ground and rolled to check for clearances. These test fit spacers are drilled to fit the standard BMW 5x120 bolt pattern as well as 4-lug 4x100 (and VW/Audi bolt patterns too). You can stack spacers to achieve the perfect clearance. When you're ready call us to order the spacers you need (Turner spacers come in 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

These spacers are not for driving on. They lack the hubcentric lip that BMW wheels are designed to work with. Driving on studs alone will lead to a failure.

Two ways to buy -

  • Own. Just as it says, you buy this kit to own. Perfect for shops or race teams that change wheels or brake components often. For shops you can measure wheel clearance and order the correct spacers the first time around (no wasting inventory or paying return shipping). Note: Kits purchased to Own are not returnable for refunds.
  • Rent. Pay the full price but get $110 as a store credit when you return the kit. We keep a modest $19.95 fee for the service. Perfect for DIY and enthusiasts who only need the Test Kit once. Use your store credit to purchase your spacers (or anything else from our catalog).

BMW has long suffered issues with rear shock mount blowout on M3 and non-M 3 Series models dating back to 1984 with the E30 chassis. Little changed over the following two decades, and E36, E46, and Z3/Z4 models are also prone to this style of failure. After striking a pothole or another seemingly innocuous obstacle, a clunking from the rear emerges and handling becomes sloppy. Your shocks have blown through their mounts. Enter the Ultimate Performance Rear Shock Mount Kit from ECS Tuning. Not only does their industry-first design alleviate the blowout problem once and for all, but allows rear dampers to fully articulate, for the best possible damper performance and longevity. They accomplish this with no noticeable increase in noise, vibration, or harshness (NVH) thanks to their unique rebuildable polyurethane isolation. The poly bushings not only keep NVH to a minimum, but they also reduce impact loading on the bearing, improving bearing life over full solid mounted monoball designs. To further improve bearing life and longevity, this design incorporates a lower dust seal to keep road debris, grit, and other contaminants out of the bearing. These are one of the best rear shock mounts available, and the last you will ever need. Features: Maintenance-free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation Lower dust seal for improved bearing life 80A polyurethane isolation bushings for NVH control and improved bearing life Accommodates 10mm* Fully constrained shaft mount makes blowouts impossible Hard anodized 6061-T6 construction Class 10 black zinc plated studs New OEM lock nuts included Fully rebuildable design *For use with factory-style 10mm damper shafts. If you have factory-style mounts presently, you have 10mm damper shafts. *During installation a 17ft-lb torque spec is required to avoid damage to the mounts.

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. 

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.

  • Ease of Installation: Wheel studs simplify the wheel installation process while the nuts secure the wheels in place.
  • Reduced Wear: Wheel studs in the hub reduce wear on wheel hubs, compared to frequently removing and installing wheel bolts, enhancing longevity.
  • Quick Tire Changes: Wheel studs facilitate swift and effortless tire changes or removal.

*Note: Apply thread-locking compound during installation and torque studs to 15Nm. These studs support spacers up to 10mm in size.*
