Power Steering Kit for 1982 - 1991 BMW E30 by Chase Bays
The Chase Bays Power Steering Kit for BMW E30 is designed to eliminate the common factory power steering leaks, fluid spillover, and overheating issues with improved aesthetics, durability, and stealthy design. It is a full 100% upgraded A.N. fitting replacement of the stock reservoir and hoses. From the reservoir to pump to rack.
Chase Bays' over-engineered Triple-Baffled Power Steering Reservoir (aeration and spillover proof) is at the core of this kit. It optionally comes with an upgraded black aluminum heatsink cooler that mounts on the upper core support (see photos) for easy install and additional airflow. Chase Bays only uses the highest quality components available. Our reservoir is constructed of 6061 aluminum and is anodized black with a laser etched cap. The reservoir itself uses our Delrin Shim Bracket to conveniently use the OE BMW Reservoir Bracket.
Countless hours of research and development were put into their newest Power Steering Reservoir. This isn’t as simple as putting 2 fittings on a fluid container and calling it a day. It is far more complex. The smaller fitting on the Reservoir is the fluid return from the rack. It can be sent back at pressures up to 120psi. When that hits the fluid in the reservoir it can cause extreme foaming aeration if not properly slowed down and directed. The more the steering and RPM on the car, the higher the pressures will be. This is also what commonly causes the spillover through the cap under heavy use. Most people think their fluid is boiling over when this happens but in most cases it is not just turbulence.
In the reservoir photos you can see a "chimney" inside, there is a multi-layer design within this chimney. Chase Bays won't give away all of their secrets, but just know you won't have any aeration or spillover issues. Between on track testing and computer fluid dynamics, they were able to slow down 120psi to 12psi in 2 inches of fluid motion. Thats just 2 of the baffles, it doesn’t end there.
Power Steering is a loop hydraulic system so it needs to be vented. The cap has a unique baffle design to block fluid from pushing out the vent. Go to any road race/drift/rally event and look at all the factory (and most aftermarket) power steering reservoirs. By the end of the day there is spillover all around the reservoir. It was their goal to be the 1 in 100 reservoirs to have no spillover. Chase Bays is proud to say; that goal has been met.
Please Note: For 1/2JZ-GTE swapped E30's only, this will not fit stock option E36s. Must change Power Steering Pump to non 2JZ-GTE VVTi, the stock variable pressure pump will cause unsafe steering irregularities.
