Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. BMW introduced VANOS in the early 90s, and it added variable valve timing to the straight six engines. Over time the VANOS unit wears out which can cause error codes or VANOS rattle. Race German has sourced quality replacement parts in an easy kit. Seal Kit: 1 PTFE Teflon Ring Seal 1 FKM (Viton) O Ring Seal 2 Copper Oil Pipe Washers Anti Rattle Bushing Set (1 Bushing + 2 Bearings) OEM Vanos Sealing Gasket *Note: a modified 18mm socket is needed to disassemble the VANOS unit. We are now offering this socket at a small charge. If you have a 1993 model single VANOS car, the 18mm socket will not work. You will need a modified 17mm socket. This kit includes the modified sockets.

Virtually every top professional BMW engine builder relies on ARP Pro Series head studs. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated to 200,000 psi, ensuring complete heat penetration. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best head studs we've found for the E36 6 cylinder engines, and we highly recommend them in both the racing and forced induction arena. (Due to the additional clamping force between the head and block, these are IDEAL for turbo charging and supercharging!)

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently (and quickly!), and also ensures proper alignment of the head and gasket. Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set. Kit includes everything pictured -- 14 head bolts, washers, bolts and assembly lubricant.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

These head studs fit the following BMWs/engines (steel block only)
1992-1995 M50 6 cylinder including 325i, 325is and 525i
1996-1999 M52 6 cylinder including 328i, 328is, 323is, 528i

This ARP main stud set for the 24 valves M50-based 6 cylinder engines (including M50, M52, S50US and S52US) and eliminates main cap walk and fretting, as well as protects the threads in your engine block. Each stud is made using the best materials, process, design and engineering, which exceeds even the most stringent racing and aerospace specifications. This main stud kit includes hardened parallel-ground washers and aerospace quality nuts. Replaces BMW part numbers 11-11-1-713-525 (11111713525) and 11-11-2-244-286 (11112244286).

The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 190,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others. On the E30 M3, there's no reason to settle for anything less than the best, which is why we carry and use ARP fasteners and studs on our own BMW race cars.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

If your vehicle has started leaking coolant around the intake area and it is not the pipes, it is probably the valley pan.

This URO replacement has a high temperature and chemical resistant FKM Fluorocarbon Viton® rubber gasket to reduce the chance of leaks and increase the life of the gasket. This valley pan also features a gasket retention step to keep the gasket in place during installation and also reduce the chance of the gasket blowing out from pressure.

Virtually every top professional BMW engine builder relies on ARP Pro Series head studs. ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated, ensuring complete heat penetration, to increase the clamping load up to 200,000 psi. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best head studs we've found and we highly recommend them in both racing and forced induction applications. Due to the additional clamping force between the head and block, these are IDEAL for turbocharged engines. 

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently (and quickly!), and also ensures proper alignment of the head and gasket. Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously. A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set.

What's better than using new crank bearings in your next engine build? WPC-treated bearings! What is WPC, you ask? WPC is a surface treatment that reduces friction and adds strength - two improvements that benefit internal engine components. Ultra-fine particles are fired at the surface at very high speeds, like shot-peening - but much, much smaller. The parts come out smoother and stronger due to thermal discharge. The two largest enemies of any high-performance engine are heat and friction - and WPC has found a way to reduce both. What are you waiting for? Use WPC-treated bearings on your next engine build or crank service!

Upgraded valves designed for high horsepower applications! Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design, we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. It’s unlikely you will find any of our competitor’s valves with stricter dimensional tolerances than our Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere! Optimum high flow rates are achieved by ensuring that our valves are manufactured with the best angles for each application. We consider back cut, under cut and valve head angles for each application to produce the optimum high flow rates for each application. In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves at no additional cost. When our Superfinish is combined with our Black Nitrided valve, it reduces the surface roughness to 1/3 of our chrome coated valve. The end result… unsurpassed performance and durability. Our intake valves are made exclusively from an enhanced versions of EV8 (21-4N) steel. Black Nitride Coating: This is a hardening treatment that has been steadily growing in popularity over the last several years. These black Nitride coated valves feature harder surfaces and smoother finishes, providing less friction and subsequently longer life. Please see below for more benefits of our Black Nitride valves. Black Nitride Coating Head Diam: 33mm Material: Stainless Steel 21-4N Groove Type: Triple Groove Length: 123.7mm Stem Diam: 6.95mm

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. BMW introduced VANOS in the early 90s, and it added variable valve timing to the straight six engines. Over time the VANOS unit wears out which can cause error codes or VANOS rattle. Race German has sourced quality replacement parts in an easy kit. Seal Kit: 1 PTFE Teflon Ring Seal 1 FKM (Viton) O Ring Seal 2 Copper Oil Pipe Washers Anti Rattle Bushing Set (1 Bushing + 2 Bearings) *Note: a modified 18mm socket is needed to disassemble the VANOS unit. We are now offering this socket at a small charge. If you have a 1993 model single VANOS car, the 18mm socket will not work. You will need a modified 17mm socket. This kit does not include the modified sockets.

These Schrick camshafts are the same specs as the stock US S50 cams -
Intake: 252 degree, 10.2mm lift
Exhaust: 244 degree, 9.5mm lift

With original S50/S52 cams in short supply, and a new set running over $2,000 from BMW, you can source new M3-spec cams from Schrick. These are the same specs as the US S50 engine and very close to the stock S52 cams. These make a great upgrade for M50 (325i, 525i) and M52 engines (328i, 528i) with the proper tuning. These bolt in just like the stock and M3 cams with no special hardware upgrades required - use your stock valve springs, lifters, etc. But for reliability we recommend replacing the lifters, valve springs, and retainers with new stock parts on high mileage engines.
