The steady march of progress at BMW M happens both publicly and behind the scenes. Publicly, BMW M has moved to the use of composites to lighten their newest M cars, direct injection and turbocharging to usher in a new era of efficiency and high power output, and advanced suspension designs to give M drivers even more of the response and road feedback that makes BMW M famous.

Less in the public eye has been BMWs battle with chassis rigidity. The M2 has over 20 distinct chassis braces... the M4, even more. Although this myriad of braces typically goes unnoticed by the average M owner, the engineers at M understand that a rigid chassis is the foundation of all other performance delivered by any M car.

While the M2 gracefully balances manufacturing cost, MSRP, and incredible performance, the cost savings does result in some components that are not optimized in their construction and engineering. We’ve found that the front support braces found on the M2 are one such component, and have worked with RKP to improve on the original BMW design. What started as a project intended only for IND’s own M2 has transformed into a low volume run of the RKP corner braces, available for those that are interested in improving the appearance and rigidity of their M2s.

RKP’s Corner Braces are constructed from Stainless Steel or Titanium tube, and constructed with design principles that lead to a more rigid part in both bending and torsion, giving the M2 an even more dynamic feel and driving response.

As these were created for our own M2 first and foremost, the RKP Corner Braces are available as a limited, low volume production run.

Thanks for the kind words!

this looks really good in combination with the eventuri. Added to my wish list.

Thanks for the kind words! Let us know if you have any questions regarding the corner braces.

Nice, but too costly.

Anyway of making adapter brackets [to sell as an additional add-on purchase] for M235i retrofit ?

This would broaden the potential market ie non-M F2x + F3x sedan/coupes etc to up the demand and then hopefully reduce the price point as 5 bucks under a thou is too steep IMHO

[marco_polo]

^ Agreed.

If you could produce a version which used the M235i's strut-tower bolts, I'm sure you couldn't make them fast enough! I really like the matte black.

Now offered in titanium

Titanium RKP Corner Braces are in stock.

IND, how exactly did you determine that the factory bracing was insufficient here? Was any concern given to the possibility that any flex or weakness in the factory braces may have been there for crash safety reasons?

It's not like it is hugely expensive for BMW engineers to just specify a thicker cast/stamped piece. They presumably had a stiffness target to hit, and reached it with the braces included on the car. I understand that there are always cost-cutting measures in place, but if they had doubled the thickness of the bracket I can't imagine that would've been a big cost relative to the rest of the car...

Explain to me why the heck I would want to blow $1k on your welded tubing (with many more potential points of stress failure due to the welds)? Is your part lighter than the factory piece?

Those raw and titanium look awesome, but that's a ton of cash

The factory braces are a part that is unchanged from, and shared directly with the 2 and 4 series convertible chassis. It is not included on the coupe counterparts at the time of production, and making the part cross compatible eliminates the need for additional design and tooling, which translates to cost savings.

On the M235R, BMW Motorsport utilized the carbon fiber strut brace from the F8X M3 / M4 to increase chassis rigidity even though it added weight at the front end of the vehicle. Though the RKP corner braces are marginally heavier than the factory pieces, they improve upon the factory design by being more sturdy, thus translating to less flex in the chassis.

Any thoughts on which offers a more rigid front end, the F8X carbon fiber strut tower brace or these RKP braces?

Nice pieces. With these units installed , will the DINAN intake fit ?

These will not work with the Dinan intake unfortunately. Haven't had any issues with other intakes though.

[KevM2]

Can anyone who has upgraded their corner braces attest to the improved handling? How would this upgrade compare to a strut brace instead? Thanks
