  • Tig welded joints with 70S rod (specialty for 4130 welding)
  • 6-point style cage
  • Sheet metal gussets in critical areas
  • Custom driver's side door bars increase strength compared to standard NASCAR style

  • "A" pillar vertical tubes (aka FIA bar)
  • Windshield frame bar, door bars, and main hoop are all stich welded to the chassis for increased rigidity
