    Any ideas on where to reinforce and tie in the suspension on a low 10 sec, 3700 lb GS, stock frame, 10.5 tire.

    My proposed ideas:

    -run a bar between upper spring perches and /or run X bar from roll bar thru package shelf

    -reinforce control arm mounting brackets, even with the Hotchkis connectors

    The upper x-member for the rear shocks and springs should be tied in w/ the rollbar/cage.
    And it's a good idea to tie the forward mounts of both upper and lower control arms together.
    Then you can install an anti-roll bar to control the twist.
    Most important is the cage going directly to the frame.

    Thanks Gary
    So basically I'll try to box the whole rear frame attachment points, right?
    What about my idea of an X from the roll bar thru the package shelf? Any advantage to an X vs. the bar going to the spring perches and maybe adding a bar between the perches?

    Here is,in my opinion the only way to go over the rear seat,it looks more professional.
    This is the car we had in mind when we did my cage.
