Has anybody here successfully installed and used a Kirk Racing Weld-in roll cage for SCCA and/or BMWCCA club racing? My understanding is that a custom cage by a reputable cage builder is always the best way to go, but I'm exploring all of my options. The cage would be for an e36 M3. CR legality is critical. I'm assuming proper installation is just as important as the cage itself, so I would have somebody reputable complete the installation. The product description does say NASA/SCCA/BMWCCA-approved, but GCRs change, the description could be outdated, kirkracing.com doesn't clarify, etc.
