If you’re adding frame connectors, you may not need to go through all that trouble of welding in the cross brace mounts.
Personally, I think I’d pass on that project. Unless you plan on doing some serious pedal mashing with some really sticky rear tires...
I'm having the debate with myself whether it's worth installing them and repainting the bottom of the car. I've got the Hotchkiss subframe connectors and the L braces I ordered 3 weeks ago are still back-ordered. Just finished swapping a 416 LS stroker and 4L80e into the car and I want to drive it. Just don't want to destroy it, but I'm thinking the subframe connectors are providing way more support and rigidity than those L-brackets and x-brace ever would have.
L braces are for body frame rigidity at rest.
Frame connectors are for reducing body torque as a result from racing the car down the street foot to the floor.
So your going out on a Sunday drive with 5 people in the car and trunk full of weight...do you want body braces or frame connectors?
I will put the frame connectors when the rear window smashes from the torque. Verts don't have the support the coupes have. You need the bracing. When you can't open the door anymore you know the pan is gone.
