Strengthening Chasis

[JoeliusZ28]

well my car has 93,000 miles on it now, and it just seems that there are squeaks and rattles coming out of the woodwork lately. The chasis just doesnt seem to be as strong as it used to be. My car also has perfect original rear quarter panels, that I am afraid arent going to stay that way for long. I can point out what looks like the very beginning of "flex dimples" when i look at it in the right light, and I know the deterioration of a metals strength tends to be exponential. Honestly my 110% stock 99 V6 feels more rigid.

My car already has kenny brown double diamond SFCs welded in, and have been on the car since before I bought it. Is there anything more i can do to help the rigitidy of my car? Ive heard you can double up subframe connectors (I have seen the type that tuck up like i have, and the kind that hang down). I have never seen any proof of that though.

I also do not want to install a roll cage.

suggestions or am I just gonna have to grin and bear it?

have you changed any other suspension parts? Like the lower control arms and such? If not, that is where I would start. Replace all your original suspension parts and your car will ride like heaven man. Trust me.

I have tubular LCAs and a panhard bar. I also have poly bushings on my sway bars, but i believe they are stock swaybars.

I know my car needs new shocks at the moment also (stock POS deCarbons that were supposedly "replaced") but I am trying to keep that factor isolated in my head. I still have the stock torque arm which is on the list to go also.

I am planning on doing the nice Koni suspension eventually, but Im kinda broke after dumping 2500 into my engine this summer.

put a bar in it, there really isnt any other options. Adding strength by doubling the SFCs still doesnt solve the problems with the upper body flex, which is what causes the stuff to bend

Keep your t-tops in. :tt2:

Sounds like suspension should be next on your list. Shocks and swaybars will make a huge difference in handling/ride quality, not sure about rigidity.
