Replace the flimsy plastic bleeder screw used in the coolant expansion tank or in one of the cooling system hoses with this high quality, durable, aluminum bleeder screw. The stock plastic screw can deform over time due to heat or even regular use. We have even seen the head of the screw snap off, leaving the threaded body stuck in the expansion tank. This aluminum screw will help to prevent sudden failure of the bleeder screw, which can result in immediate overheating of the car.

ECS Tuning's Aluminum Coolant Bleeder Screw replaces Genuine BMW Part Number 17111712788

This braided stainless steel line replaces the stock hydraulic hose connecting your clutch slave cylinder to the clutch master cylinder. There are several deficiences with rubber, especially as it ages - when new the rubber expands and swells under pressure and the pedal can feel spongy. As rubber ages and is exposed to extreme temperatures the rubber can harden and even shrink (common on brake hoses), which results in a stiff pedal. Rubber clutch lines do not stand up to the stresses of hard use. ECS Exact-Fit stainless reinforced clutch lines provide more confident and dependable shifting by maintaining consistent line pressure, long lasting corrosion resistance, and increased protection from failure. These lines are reinforced with braided stainless steel mesh, affording superior expansion resistance. This resistance to expansion creates a firmer pedal, and a more direct clutch pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion.

This particular stainless steel clutch line fits the following BMWs:
1999-2005 E46 3 Series (all) including 323i, 323Ci, 325i, 325xi, 325Ci, 328i, 328Ci, 330i, 330xi, 330Ci
2001-2006 E46 M3 (manual transmission only, no SMG)
2004-2009 X3 SAV including X3 2.5, X3 3.0

Your floor jack is universal but it doesn't have to be with this adapter! Most newer BMW jack pads have an open recess inside that this adapter fits into. It's a rectangular peg for a rectangular hole. This gives the jack a much more rigid connection and almost impossible for the jack or pad to slip. You will never have to worry about scratching your rocker panels or jacking from the wrong spot - the positive connection ensures you are always lifting from the correct location. This adapter is one of those small hidden gems that you can't live without! 

Made of black anodized aluminum for added strength and corrosion resistance, the adapter fits the head of most hydraulic floor jacks, including the Schwaben Low Boy.

Compatible with most BMW jack pads for chassis E39 and up. Retrofitting jack pads is common, especially on E36/Z3 models.

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 (we make 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

This kit is for purchase only. It's perfect for shops or racecars where changing wheels or brakes is common. We also have kits that are available for rent.

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.

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.

Key benefits of the adjustable hose clamp include:

• Maintaining a secure and leak-free seal in your BMW's systems.
• Preventing coolant or vacuum leaks that can affect performance.
• Adjustable size from 70mm to 78mm for versatile applications.

Upgrade your hose clamps to ensure optimal performance and reliability in your BMW's systems.

From years of European automotive experience, the enthusiasts at ECS Tuning have developed a strong understanding of what it takes to produce a high-quality brake pad. After thousands of miles and many different pad compounds, they've landed on the ideal blend for the new DD23 "Daily Driver" brake pad! This enthusiast-developed pad offers confident stopping power, very low dust, quiet braking, and a positive initial bite. The perfect choice for your daily-driven Euro!

If you find yourself “pumping the brakes” over the brake pad selection process for your daily driver, your answer is this DD23 pad. This is the one!

As a team of enthusiasts who own all types of European cars, we have the advantage of the exposure that comes with the enthusiast lifestyle - and have a strong understanding of what makes a great brake pad. In the pursuit of a really great brake pad for daily driving, we’ve tested a wide range of brake pads. After thousands of test miles, iterating through a variety of pad compounds, we’ve landed on the ideal blend for our DD23 Daily Driver ceramic pad.

Features:

Good stopping power - Brake pads need to stop your car, period, so this is key. We focused on selecting a compound that offers a healthy level of friction (both when hot and when cold) for safe, positive stopping power.

Positive initial bite - You should feel your brakes engage as you press the pedal, but it should not feel like an on/off switch! Advanced ceramic composition means you’ll enjoy a smooth transition on and off of the brake pedal, meaning your passengers will have a comfortable ride in stop-and-go traffic. We’ve hit a good balance here.

Very low-dust - Some factory-installed pads are eye-poppingly dusty, which is a no-go for us. Thanks to the composition of this ceramic pad, which is copper-free and contains a negligible amount of other metals, dust is both lighter in color and very limited in amount. We’ve improved on the “dust factor” without sacrificing on bite and stopping power as a good compromise, which will be a win for anyone who doesn’t detail daily (or anyone who does, too!)

Quiet braking - It’s not a race pad, so it shouldn’t squeal like one. Extremely low metallic composition means they will not squeal. DD23 is comfortable and quiet - both on the ears and in lack of vibration transmitted through the cabin.

Long life - This should be an obvious one. Your daily driver pads should last and last, so that was key in selecting our ideal compound. This is another benefit to having ceramic material composition versus a softer organic pad (which have higher metallic and various organic elements) and wear much faster. Ours are kind to rotors, too (no accelerated wear characteristics) for many miles of motoring.
