This chassis is as stiff as a wet noodle!

I have a 90 coupe that had a lot of hard miles on it, once I installed the subframe connectors, g-brace & strut-tower brace it made the car much stiffer and handle much better.

I have the MM setup too, and it helped a lot, but if you need stiffness in the back, hrmm maybe a pan hard bar and torque arm set up, those are for the rearend area.
