Sub-frame stiffening

[Silver3tiger]

I have been looking around for a way to stiffen the body. We all know how flexi the 1g/2gs are. I alrady have f/r strut bars, Would rather not go for a roll bar. Any info would be great.

S.T.

Your profile states that you already have urethane bushings, which would have been my first suggestion. Next I would add the rear sway bar. Either suspension techniques or RMDSM.

After that you're going to either have to step up to solid metal sub frame to frame bushings, or do some extra reinforcement using time, engineering, a MIG welder, and some 1x1 square tubing.

Can you buy those solid bushings anywhere? What is the trade off of having the solid bushings in the car? suspension clunk around more?

There are only two ways to stiffen the body: foam in the pillars or a cage. Yes, you can stiffen the suspension using harder bushings (all the way up to sphericals) and, yes, you can stiffen the connections between the subframes and the body, but to get more torsional stiffness in the body, there are only those two ways.

There are 3 btw. Add seam welding to the mix.

But can you pay places to do the foam? My car is getting fully stripped and I am looking for something easy that isn't super involved to eliminate noise and make the chasis a little more rigid.

STIs get Subframe connectors, along with Fbodys and other cars

I wonder why DSMs havent yet? Maybe ground clearance?
