SLR Speed BMW E46 Rear Floor Subframe to Shock Tower Brace
Couldn't load pickup availability
This rear floor to shock tower brace closely follows how BMW Motorsport reinforced the factory E46 GTR and touring car shells into the rear floor/subframe location.
This brace performs several functions:
- Rear floor reinforcement to combat stress fractures at subframe mount locations
- Rear shock tower reinforcement to allow coil-over-shock (aka true coilover) installations.
- Lateral reinforcement and structural replacement after notching the factory floor crossbeam for Quick-change differentials.
- Longitudinal torque load distribution for less overall floor flex under hard acceleration (basically it stops the rearward subframe points from pulling down as the differential applies torque through the subframe)
Includes hardware to bolt into the rear floor/subframe threaded tubes, or you can use your own M12 all-thread to allow through-bolting with subframe below, plus nuts in cross bar feet.

Worked as they should. Quick shipping

Brand new in sealed bag, correct product delivered.

Good deal, comes as described!

Arrived in perfect shape

When first purchasing the kit, it was very straight forward. I told them what I was looking to do, they directed me to the exact kit with everything needed included.
I recently had an issue with one of the struts, and FIP very quickly responded and handled everything with Silvers. New strut arrived at my doorstep within days.
Highly Recommend ordering with FIP.

Great experience, order got messed up and Brian made sure to get it fixed and kept me up to date by texting me.

Customer service was great. Order shipped quick. Great value and the change to the car was better than expected. Wife no longer braces herself for the expansion joints and other Ohio road issues.
