RS Sport Suspension

[JBScat]

Hi,

I just ordered the GM 23158162 RS Sport suspension kit. I plan to install it the week between xmas and new years when Im home from work (can do a write up if anyone is interested).

My question is for anyone who has this, did you consider adding the DDM rear suspension brace? Will it make a big difference the the RS handling pack?

Thanks
John

The GMPP package is not bad at all, but the DDM brace makes it better

I'm curious what changes GM made to the rear RS shocks to accomodate 10mm lowering springs? That wouldn't seem to be a big enough change in ride height to require a change in shock body length.

After installing the ZZP lowering springs & rear anti roll bar on my son's Sonic RS hatchback, I suspect the design of the rear bump stop could have something to do with it. The rear bump stop fits into the upper shock mount at the top, and the splash guard at the bottom. That makes it difficult to trim the bump stop to allow for additional suspension travel with the lowering springs. The front bump stops fit under the splash guards and are easier to trim.

That was the 2nd generation RS ? I never found a bump stop on my 13 i had the DDM brace I hated it sold it no more that a month after buying way too stiff and the creaks and noises it made but that's just me. I would rather have the ZZP rear sway bar I'm running 17X9.75 wheels 215/50/17 tires I'm glue to the road brace /rear sway bar delete lol
