Steve those are pics of the Tequipment rollbar.

Loran, if you are interested in the cage/etc they are called clubsport/RS parts

the only place to reliably get them with a good reputation is www.Carnewal.com - no affiliation just incredibly satisfied and have ordered LOTS of stuff from them. they have NEVER let me down.

dealers have a hard time getting motorsport parts and the prices are rediculously messed up - I don't trust anyone else when it comes to getting hard to find parts.

Just so you don't get over your head - the clubsport/rs cage requires welding to attach - which permanently alters your car. For most track events the tequipment bar more than fulfills safety and regulation requirements.
