I came across the x subframe connectors for my corvette. Are they worth it? Anyone have them? Any thoughts on them

i recently added the r-d racing cross frame to my vette.the car feels a lot more solid.it feels tighter in turns and no more rear end wiggle when i change gears hard.with this and the r-d camber brace it drives so much better and doesent feel like a 10 year old car with 98k miles.the shocks are next.......

I agree with the previous post. I have the RDRacing roll bar in addition to the CrossFrame and CamberBrace. My car is really very stiff torsionally. Really handles well. You will notice a big difference with an X brace when the Targa Roof panel is removed.

it was standard on the verts... and nice on the coupes.

I think the x-brace was standard on the Z07 coupes, too.. someone confirm this?

I have the R-D Cross Frame, like other have said, really helped out the stiffness and handling.

I have a 91 Z-07 the first year for the option, NO X Brace. There may be some thicker gussets somewhere but nothing apparrant.

I guess Ill get some pricing done.
Does the braces get in the way of exhaust? As in when I switch to headers will it get in my way and may need to be taken off to do the job?

Can anyone report how much if any ground clearance was lost with the RD Racing Cross Frame? My car is pretty damn low and I don't know how much more clearance I can afford to lose.
