700/900 rear subframe reinforcement kit

This kit consists of five plates laser cut in 16ga steel to the appropriate shap to box /reinforce the rear subframe.  The 7 and 9 series cars have a problem with the rear subframe twisting enough to eventully break the torque arms during "spirited" driving of after some modest power upgrades.   If you do not have welding ability, this is a job that could easily be done by your local muffler shop for a few dollars.
