Rear torsion beam configuration questions...

[mk6sean]

To those who don't know me... I drive VW's. My girlfriend has a sonic that we're piecing together....

Anyhow! I noticed while installing coilovers on her car that Chevy went with a torsion beam in the rear... Since the coilover install, the back end handles like crap and constantly is bottoming out. In the VW world, subframe swaps are common. My 2013 Jetta came with a torsion beam and I swapped an independent rear suspension subframe into it from the previous generation (2008) the swap was plug and play for the most part, and I'm pretty sure cruze's have the IRS subframe (correct me if I'm wrong)

So has anyone here make the attempt to retrofit one over to the sonic?

If it's possible, it's something we'd probably like to do. I'd just like to get some input since you guys know way more about these cars than myself.

thanks,

- Sean

Nothing to swap it out to, everything gamma has the same type of rear suspension. (To my knowledge)

If it just happened when you installed coils, I would be looking at the coils not the rear axle.

You may need some stiffer springs in the back, MPfab has a article on here for people who are not happy about there coils. Ends up running like a 5.5K spring in the rear vs the 3k
