Description Technical Specs Extended Information
We've been kicking around the idea of doing a new front upright(also called a knuckle) for almost 15 years! About 3 years ago we started in earnest to design our own Ultimate Upright.

There are several reasons to improve upon the stock design. To see details go to the "Extended Information" tab.
1. Suspension Geometry improvement.
2. Strength & Weight
3. Wheel selection
4. Braking improvement

The BWR design features:
  • Highest FoS(Factor of Safety) design available even compared to stock uprights!
  • 2lbs lighter than stock uprights!
  • Made from Aircraft Grade 7075-T7351 NOT 7075-T6 because of it is far less susceptible to corrosion cracking
  • Uses thread inserts AND ball joint taper insert(all stainless steel) for toughest, robust design.
  • Wide brake caliper selection available.
  • Allows ride heights from stock all the way down to 90mm
  • Reduces roll-center migration by 1/2.
  • Reduces excessive camber gain to keep the effective camber while cornering in a more optimum window.
  • With stock steering arms you can get -3 degrees front camber at 110mm ride height.
  • Fit most 15" wheels on the front
These ideas have been designed in software, tested on the track, and proven with Wins and Championships.
  • -Improved Geometry for lowered cars
    -2lbs lighter than stock uprights
    -Designed to be stronger than stock steel forging.
    -Stainless steel inserts
    -7075-T7351 aerospace aluminum to resist corrosion cracking
    -fits most 15" wheels
    -More brake options
