The Rogue Engineering RACEBRACE Strut Tower Brace reduces the flex between the front strut towers during hard cornering loads, giving you the feeling of increased stability and improved turning response by allowing your suspension to work as designed.

This strut brace can be used on ALL 2002-2006 BMW E46 M3, as well as all 2002-2005 E46 4 door sedan/wagon and all 2002-2006 E46 2 door coupe/convertible.  

The RACEBRACE can benefit street driven E46s just as much as track or race cars. The benefits aren't just something you feel through your suspension, but the brace will also protect the strut towers from mushrooming if you hit a large pothole, which if left unprotected, can cause expensive sheet metal damage. Needing new strut towers welded in is an expensive pain that can easily be avoided.

Not all strut tower braces are created equal, though, so in order to get the most benefit, you need these features:

  • Sufficient protection of the strut tower top (to prevent mushrooming)
  • Center bar with minimal bends or kinks (straighter is stiffer!)
  • Provide adequate under-hood clearance (so not to dimple the hood)
  • Allow for suspension changes (for those that frequent the track)
  • BMW applied many of these traits to their own strut tower braces for the E36 and E46 models. Both used cast aluminum strut tower plates combined with tubular steel center bars.

  • Features:

  • Lightweight tubular steel bars, 100% TIG welded to high-strength steel plates and powder-coated black for a durable finish
  • Multiple-bar configuration with center support bars resists twisting and bending of the front chassis
  • Open tower design for easy access to adjustable camber plates and shock adjustments
  • Adequate clearance over the engine components and under hood
  • Full 360° strut-tower support to protect from pothole damage, especially with lowered cars
  • Easily removed in minutes with simple hand tools - adjustments to suspension camber/caster plates possible without removing bar
  • Light weight, yet strong enough for the rigors of extreme track use

  • Installation Notes & FAQ
  • Fits all E46 M3 for the 2002, 2002, 2003, 2004, 2005 and 2006 model years. 
  • Can be made to work on 2001 E46 M3 with camber plates / longer studs. 
  • Fits all 2002, 2003, 2004, 2005 and 2006 E46 3 series (non-M). 
  • This brace is NOT for M E46 models before the 2002 model year as '99-'01 models have raised "bumps" on the strut towers that prevent installation. The 2002-2006 E46 3 series models do not have these raised bumps, allowing the RE RACEBRACE to install without issue.
  • On the E46 version, the RACEBRACE is now slotted for easier installation as well as with use with aftermarket camber plates.
  • Installation for those with stock strut mounts is a matter of minutes.
