I'd like to tighten up the 99 convertible. It has been suggested that I weld on subframe connectors, I'm guessing that means the double cross subframes. I see Kenny Brown is offering the "Extreme Matrix Sub-Frame System" I can't tell from the picture on the web what is included. However, wouldn't the Chassic Support Kit be better?

I'm a maximum motorsports fanatic myself...

but to stiffen the chassis, the two thing I would recommend are definitely full lenght sub-frame connectors, and a strut tower brace. a shock tower bar in the trunk is good too, but I don't know if that would work in a vert.

Here are the chassis items from Maximum motorsports.

The Maximum Motorsports full length sub-frame connectors are beefier than the Kenny Brown IMO. The Kenny Brown Extreme matrix comes with three items, the Sub-frame connectors, jacking rails (two metal bars that go against the lip by the door) and the active matrix bar that connects the rail and the sub-frame connectors... or maybe its easier for me to show you...everything in Red is part of the Kenny Brown Extreme matrix. The inner bar with the T in the middle is the Sub-frame connector, the rail on out parts of the car is the jacking rail (so you can jack the car up with it) and the zig-zap bar is the ative matrix.

Definitely go with something beefier than the KB stuff. There's a thread in the AutoX/Road Racing section that shows the MM and KB stuff side by side. It's obvious which one is stronger.

I will be selling my own (BMS) connectors in the next month. They are made of the same materials as MM's shorter connectors and Griggs connectors. MM uses a little thinner wall, but larger dimension in their full length connectors.

More info on my connectors are here: http://www.bananamotorsports.com/ and here: http://www.svtcobraclub.com/svtbbs2/showthread.php?s=&threadid=5298

If you don't buy mine, buy MM or Griggs. You have a 'vert, you need some strength under there.

Edit: Editted to sound less like a sales pitch and more like sound advice.

great pic of the SFC's! Me, I run the KB SFC's and I have no body flex at all. I also have the 4 point lower chasis brace, and strut tower brace..... but I also have a coupe. I think Tom would be one of if not the best to answer vert questions as he had a vert (if it still classified as that :rolleyes: ) that ate up the track.... and anyone on it.

but then again, without all that caffeine in his system he may not have that edge anymore;) ;) :eek:

:rotf: :rotf: :rotf: That is TOOOO funny!!!

My car also had the in-floor subs. That really made a huge difference! Oh yeah, and a full cage. That pretty much took all the flex out of it. :)

You have seen the latest picture of it, right?

Subframe connectors, front and rear strut tower braces, lower chassis brace, and if you are interested, a street cage.;)
