When swapping an M5X engine into your E30, interference between the intake manifold and brake booster-mounted reservoir is a common problem. Tighter clearance necessitates the use of a different brake booster, which means the brake fluid reservoir will need to be retrofitted or relocated. This is particularly difficult when using the larger, dual-diaphragm brake booster from an E32 or E34.

To solve this issue, we've designed a clean, OE-style solution that requires zero fabrication. Our stainless steel bracket relocates the brake fluid reservoir to the original, left-hand strut tower location, once used for mounting the M20's power steering fluid reservoir. This provides the clearance necessary for fitting an M50/S50, M52/S52, M54, or S54 in the engine bay of your E30.

Designed with the DIY E30 24V swap community in mind, our design delivers factory-quality fit and finish with none of the guesswork.
