Racing Heritage
Road Reliability

Lang Racing Development sets itself apart from other BMW and Porsche shops in Orange County because of our road racing history. We take many years of design and engineering experience honed in the crucible of endurance road racing and turn that focus to the daily maintenance and repair of BMW and Porsche vehicles. That experience has given us a wealth of knowledge that other shops just can’t match.

Derrick has made the painful decision to try findi

Derrick has made the painful decision to try finding a new home for his very slowly built e46 m3 track toy. This car was built with a Pavlov Racing cage fully tied into the rear subframe. The entire rear end bolts straight to the cage. We built this engine not long ago and it has been very reliable. No corners were cut on this build, this is the cleanest M3 build we have ever seen. Aim MXL2 Dash, setrab oil cooler and Ron Davis radiator with custom ducting to keep the car cool in hot California track weather. Still street driven and has never been raced. Interior was professionally painted gloss white with the car fully stripped. MCS Suspension, Brembo Brakes, Lang Racing CF Roof. Asking $54,500. @stephen.pavlov.1 @mattsracing #e46m3 #bmwccaclubracing @windingroadracing #drivenasa

This F10 M5 suffered from a pretty uncommon turboc

This F10 M5 suffered from a pretty uncommon turbocharger failure. Complete disintegration of the turbine causing this massing dump of oil into the exhaust. The intercooler acted as a barrier to protect the engine from ingesting the turbocharger guts. Stranger still these appear to be new stock turbos. This new owner was less than thrilled.

Reintroduction sale on our E46 Rear Subframe Reinf

Reintroduction sale on our E46 Rear Subframe Reinforcement Plates. We just did a large batch production of these plates and decided to put them on sale for 150$ until 9/1/2020. These plates are massive compared to what you’re used to seeing spreading the chassis loads further out. Strategically located holes allow for plug welding to some inner structural areas on the body. Don’t settle for tiny plates when you can have these for about the same price.

Had a fun couple of days working on this Ferrari 488. The ecu has to be pulled out of the wheel well for bench flashing by @hd_tuning . Made some impressive power gains on the Pure Turbos and greatly improved drive ability. If you have any special projects feel free to reach out!

After being unavailable for a couple of years thes

After being unavailable for a couple of years these Mahle Pistons in 87.50mm 11.5CR have returned. We are your best source for Mahle Pistons for your S54 in various compression ratios including the OEM 11.5 CR piston which is hard to find and would cost double if you bought from the dealer. If you're building a racing engine we recommend the 12.3 CR piston and running 100+ AKI fuel. For turbo builds up to 700WHP we highly recommend the Mahle 9.0 CR Piston using its heavy wall wrist pin that comes standard to handle that cylinder pressure. We've also recently added 11.5 CR for builds using pump fuels, or for street cars. This is a set of extremely high quality Mahle PowerPack pistons for the S54B32 engine. Mahle Powerpack pistons are extremely high quality pieces which provide improvements in strength over OEM pistons without some of the sacrifices sometimes found in other forged pistons. Mahle Powerpack pistons are precision forged from 2618 alloy, a low expenasion rate aluminum. They all feature forged side reliefs, reducing the weight of the overall package. They also use slipper skirt designs, reducing friction and further reducing weight. Mahle PowerPack pistons feature ultra flat ring grooves, which promote excellent ring seal and most importantly reduce the chances of micro-welding during break in. Every set of Mahle PowerPack pistons comes with their exclusive Grafal skirt coating, which is not only anti-friction but also offers impact absorbing qualities, reducing piston noise and decreasing stresses in the piston skirt. Mahle PowerPack Pistons are an excellent choice for those looking for increases in strength while maintaining a lightweight piston with oem fit and finish. They have 21mm wrist pins so they will require a set of rods with 21mm pins to match. #mahlemotorsport
