shaking when Topless

I have noticed this as well. I have heard the Vette2Vette solution really helps the chassis flex quite a bit. I have still wanted to run either that or X Brace from GM.

The C4 convertible "braces" on a coupe don't do much in a practical sense to improve the C4 structure, however, the improvement might be noticeable as a slight decrease in steering column shake.

They do increase weight and decrease ground clearance but, heck, they are easy to install.

I've never tested the product, but the "Vette2Vette" chassis reinforcement, looks like a better choice than the OE convertible braces.

From my personal experience the Vette2vette chassis brace works as advertised.

I have the prototypes on my car and very happy with them and I know they have made some improvements since they installed mine

My roll bars work quite well, but makes the rear view mirror useless.

Welcome to C4 ownership. The car with the top off is about as ridged as a wet piece of toast. My car tries to shake the turn signal stalk off with the top off but I still take it off at times. I have a set of Bill Bs beam plates just need to get them on the car.

While it's completely normal it tends to be worse in some cars. I have the V2V No Flex Frame Stiffeners (basically a long subframe connector with heim joints on both ends) and I still notice some cowl shake but it did improve quit a bit. I also have beam plates. Again, it still shakes but not nearly as bad. I would definitely be interested in the cross bar if anyone knows where to get them.

I took the top off for the first time yesterday and experienced this shake. I took me a little bit of time to get used to it. It certainly scared me at first. The steering wheel and dash shook on all minor and major bumps. Has anyone made a X designed metal brace that fits in place of the targa top? Would this work?

Welcome to the wonderful world of C4 ownership. The things about as ridged as a wet piece of toast with the top off. The targa truss bar will tighten things up a bit but just can't get past the looks of the thing,I can deal with the shake.
