Specs and Features

Product Description
This Bull Boost carbon fiber strut tower brace is made for G8X owners who want a chassis upgrade that also looks good under the hood. By connecting the front strut towers, the brace helps reduce chassis flex and keeps the front end more stable during harder cornering.
The carbon fiber center section sits across the front of the engine bay and is easy to see as soon as you open the hood. Choose black, red or blue to match the rest of your engine bay setup.
It fits the G80 and G81 M3, G82 and G83 M4, and G87 M2, so the same brace works across the S58-powered G8X lineup.
Installation Notes
- Bull Boost does not publish a product-specific installation guide or torque specifications for this brace.
- Do not guess the torque settings for the strut tower fasteners. Follow the correct BMW service procedure for your chassis.
- Check the position of the brace and all surrounding clearances before closing the hood.
- Recheck the mounting hardware after the first few drives.
- Professional installation is recommended if you are not familiar with removing and reinstalling chassis-brace hardware.
Before You Buy
Bull Boost offers black, red and blue versions. Use the current product photos to confirm the version you want before ordering.
Pairs Well With
- KW Height Adjustable Springs for BMW G80 M3 / G82 G83 M4 / G87 M2 - The strut brace is a smaller chassis change. The KW kit makes the more noticeable difference by lowering the car and letting you set the ride height while keeping the factory electronic dampers.
- Megan Racing Rear Camber Arms for BMW G80 M3 / G82 G83 M4 / G87 M2 - These are worth looking at if the car is lowered and you need more rear camber adjustment than the factory arms provide. They also make alignment changes easier when working around a wider wheel and tire setup.
- AutoTecknic Dry Carbon Engine Cover for BMW G80 M3 / G82 G83 M4 - This does not add another chassis benefit, but it pairs with the carbon strut brace if the goal is to finish the G80 or G82/G83 engine bay. It is not listed for the G81 M3 Touring or G87 M2.
