I have ALOT of chassis twisting (especially when riding on rough roads). I know of several cross braces that can be installed behind the seats, but I'm looking for a device that cannot be seen (i.e under the car). I know there are several units for BMW's to increase stiffness as I used to have one on mine. BMW motorsport has an "X-brace" (Im assuming it is similar to the one on convertibles) that is installed UNDER the car. It REALLY helps. Also, alot of people use strut braces that are installed between strut towers. This also makes a big difference. What is available for the C4 that isnt so bulky? My car is a daily driver. Thanks

The covertible X-brace will help.

I put a harness bar ( HardBar ) in mine. It helped out a lot.

Check out R-D Racing. Their Crossbar is the best. This will really help with flex, but it is visable. Looks good and you can put a 4 ot 5 point harness on for safety. I have their Chamber Brace on my LT4. Similar to a strut tower brace. Helps the front end on turns. I don't thinks he has the Chamber brace on the web site yet but e-maile or call dave and he will help you out.

Gary,
Thanks for the info on the crossbar, but Im not interested in putting a bar behind the seats. I want something that cannot be seen at all, but increases chassis stiffness. Tell me more about the chamber brace. Is it installed under the hood, or elsewhere? Thanks! :)

What's the website?

I'd love to increase rigidity in the 'vette once it hits the pavement again.

Only thing I can think of is the C4 convertible X brace and use it on the coupe.It mounts under the car under the exhaust and helps ties the car together.
Some drilling of the mounting holes may be necessary.

What is this Chamber brace where does it go? I have the cross bar.
