VAC Motorsports | S65 Raceware Head Stud Kit
Buy Now! $399.95 -- RACEWARE S65 Head Stud Kit
VAC has sold head studs kits that are running on thousands of BMW's around the world. We are the #1 source for race grade fasteners for BMW, period.
With a huge selection that is always on the shelf, we are ready to get your hardware to you fast!
Why are head studs better? The OEM hardware has shown to be weak in many instances. It is definitely sub-par for real performance use under high stress such as modded engines and track use.
If the head is coming off, you are switching to forced induction or you are simply prepping to drive your car hard we highly recommend switching to far superior race-grade hardware. These head stud kits greatly improve reliability, helping to eliminate movement of the of the cylinder head and in turn, gasket failure caused by inferior OEM head-bolt stretch. This is the #1 cause of premature head gasket failure, especially on boosted or high output engines.
Though more expensive than OEM, converting to one of our head studs kits will not only give added strength and reliability when needed most, but it will provide the most accurate torque readings since studs don’t “twist” into the block. All clamping forces are on one axis, and there is less force exerted on the normally stressed threads of the block. This increases block and hardware life and typically makes the head easier to properly install to the block - a blessing if your head may have to be removed more than once.
Studs make removing and installing the cylinder head on to the block a much easier task. By allowing the studs to act as a guide on to the head, your head slides on and off and also ensures proper alignment of the head and gasket for the same reason. It is similar to converting your wheel-bolts to wheel-studs.
Offical RACEWARE Pitch:
RACEWARE cylinder head stud kits are able to prevent head gasket leaks that other highly marketed brands of engine fasteners cannot. This has been proven over and over by engine builders and auto enthusiasts who purchased other brands of head stud kits only to experience chronic head gasket leaks. They ended up replacing those highly advertised aftermarket head stud kits with a genuine RACEWARE head stud kit to permanently eliminate head gasket leaks in their engines. The other fastener brands may look similar to RACEWARE but history and independent lab testing has shown that that the other brands don’t perform the same as RACEWARE Aerospace Quality engine fasteners because they lack the superior engineering designed into every RACEWARE fastener. Results are what counts, not advertising claims and RACEWARE 205,000 PSI tensile strength Aerospace Quality engine fasteners have proven to be the best fasteners for the German engines, bar none, and our customers have proven this countless times!
Designing and manufacturing the best Aerospace Quality engine fasteners for the German engines takes expertise that other companies lack. It’s far more involved than just using a quality alloy steel and rolled threads. Having designed new engines for the car makers for many years, RACEWARE has the technical expertise to properly engineer a superior fastener solution for a specific automotive application. RACEWARE‘s 40 years of engine design and racing success allows us to understand the engine operating environment and the extreme changes that occur when an engine is started at -30° F and progresses to 300°+ F temperatures. Without this knowledge it’s impossible to design the best fastener system for an engine, as demonstrated by the many failed fasteners people send us that were produced by other companies that simply lacked the engine expertise required.
Have you ever wondered about the performance claims that some companies make for their fasteners? You should. Independent testing by government accredited A2LA material testing labs that specialize in threaded fastener testing has shown that these claims are often meritless. RACEWARE™ is the only company that has a stated Guaranteed Minimum Tensile Strength for our fasteners that is independently verified. RACEWARE™ is the only German engine fastener supplier to certify the performance of our fasteners to superior Aerospace Quality specifications. Once you experience the quality and performance advantage of RACEWARE™ Aerospace Quality engine fasteners, you will see why we are the gold standard in engine fasteners for the German engines. RACEWARE™ Aerospace Quality engine fasteners are the performance advantage that professional racers depend on and you can too.
For over 40 years RACEWARE engineering has been leading the way in German car performance and engine design. RACEWARE was one of the first companies to invent high swirl, compact combustion chamber cylinder heads. RACEWARE also created record setting “modular” cylinder heads and introduced roller camshafts to the VW air-cooled engines. RACEWARE’s unique rocker arm assembly design allowed stable race engine operation at engine speeds in excess of 10,000 in pushrod engines. RACEWARE engineering has produced advanced engine designs for major car makers and developed the most airflow efficient intake port design ever measured by one of the largest car makers in the world.
RACEWARE Engineering has won nine NHRA National Event Class Titles, set NHRA national speed and ET records, and designed and developed the record-setting VW GTI 16V engine used in the Thumper Racing dragster that set four world records. This tiny 1800cc engine employed custom machined billet aluminum mechanical fuel injection that produced over 600 SAE dyno HP. RACEWARE‘s ability to make reliable, insane power for auto racing has led to the development of the RACEWARE Aerospace Quality engine fasteners that you get to enjoy today.
Decades of engineering excellence are incorporated into the RACEWARE Aerospace Quality engine fasteners that you can buy for your German car. While you can find cheaper fasteners for your car, you won’t find a better performing threaded fastener solution than RACEWARE because each kit is designed for your specific engine and has passed the test of time. At RACEWARE we are not “Marketeers”… we are experienced engine designers and engineers who devote all of our energy and resources exclusively to producing the maximum performance and reliability possible from the German engines. We don’t use phony names for the alloy steels that we use to produce RACEWARE fasteners, nor do we make unsubstantiated performance claims for our fasteners as some companies do. We simply deliver the best engine fasteners available for the German engines. This has been proven in actual street and track use and in independent lab testing. We are the no B.S. source of the best engine fasteners available for your German engine.

Goes without saying supercharged guys who are upping their boost a bit should be running these. Head studs are a huge pain in the ass for the S65 at least they have been.Stage 2 or 2.5 E9X M3 S65 V8 supercharger kit for sale: http://www.boostaddict.com/showthrea...r-kit-for-sale
