The front of the subframe needs support more than the rear subframe does. The stock sub is terrible in torsion ahead of the firewall. The front sheet metal contributes to half the front torsional rigidity. jlwdvm, - If you do a roll bar or cage, I highly recommend adding a diagonal brace to the main hoop. SCCA requires it, and it's a main component of any good roll bar. It can be removable by adding some double shear brackets.
