Z/28 Suspension from Chevy or Aftermarket?
I'm in the planning stages of getting more serious with my build and was curious which was my best route to go as far as suspension goes. It's a weekend toy, and will see primarily street use with some recreational usage.
My goal is to be able to go to the track or strip and have a good time with it, but don't want to entirely ruin the enjoyment of driving it with the wife on occasion. I don't need or expect a ride as soft as stock or anything, but I'm not looking for a dedicated track car either. Would the Z/28 be a solid option, or would I be better off looking at aftermarket options? Thank you all in advance for any help or advice!

My understanding is the Z setup can be pretty harsh but another good option would be a set of Bilstien B6’s on a set of BMR or DSE 1-1.25 springs any lower and your gonna be draggin on the ground an ruin the ride and you get into rear drive line angle issues with the half shafts. If you’re thinking about a Z28 setup I don’t think it will do very well on a drag strip due to weight transfer from front to back or a lack there off.

Stock suspension currently? If primarily street use I'd lean towards the Z28 parts, at least as far as arms and bushings go, as they were designed for "track-ready" use and are also cheaper than aftermarket.
Not sure what to suggest for shocks/springs for drag use, but as mentioned Bilstein's B6's with BMR or DSE springs were highly recommended by JusticePete for street and light track use. JP also said you can't beat the ride quality of Ridetech, but you're paying a pretty penny for those. In any case I'd recommend solid subframe bushings as they make a world of difference in stabilizing the rear on both cornering and accelerating, and don't (in my opinion) degrade the ride quality much if at all. If you're still running the original rear sway bar (2010 - 2011 design) I'd also highly recommend upgrading to the new design - you'll also need 2012 - 2015 rear lower control arms to do this. The new, longer sway bar makes a huge difference compared to the shorter one, and helps for both cornering and launching. Perhaps go with 1LE or ZL1 bars, depending on your tire sizes (I have the JPSS bars and the rear is pretty stiff admittedly, but that doesn't bother me).

I run the Z28 set up, but with the ZL1 rear bar. The crown jewel of the Z28 gear is the shocks and springs, but they are expensive new. I would go aftermarket before I would pay 5k for the DSSV shocks and springs. I bought mine used off an SCCA racer and while I really like them, they are not nearly worth the retail price IMO. You can definitely tell the difference over a 1LE set up, but I don't find them too harsh for a street/race car. Hitting a pothole reminds me of bit of a lowered mini pickup in the 90s. I would not run the Z28 bars without the rest of the suspension because they are smaller to prevent lifting a tire in a turn. The 1LE and ZL1 use 28mm bars and Justice Pete recommends a 32mm bar for the track. A lot of that depends on tires.

The Z28 shocks and springs are a combination designed by the factory for road racing the GenV. Based on what I read, the only way to get better performance was to go with a coilover system, but that required a good bit of experience and knowledge of suspension geometry I don't have. I think they are an excellent choice for someone looking to do some track days and still drive on the street. I personally really like the setup and don't find their behavior on the street obnoxious at all.

If you are not a serious track day driver, the Z setup will most likely be too stiff for you. I currently have the Z setup on my '14 1LE with the exception of Detroit Speed springs and matching anti-roll bars. But I did run the Z/28 springs and anti roll bars originally. The springs are very stiff as are the dampers.
I think on your 2011, you would notice a nice change with just the 1LE setup, which would be the springs, dampers, anti-roll bars and suspension arms. And if you want it lowered, then the Detroit Speed drop springs would be a good choice.

1LE Springs are the same as all SS’s. Just be aware that if you go past 1 1/4 drop you’ll need to get some offset Diff bushings to spare the axles from premature wear on the CV’s.

Aftermarket coilovers over DSSV shocks and struts. The other suspension parts will be hard to beat. The DSSV shocks and springs are a money pit. Not rebuildable, and can only be replaced with a used strut if you find one. No one makes a strut or shock to work with the high rate Z28 springs. So when they leak out you need a replacement you will be going to a $3000 plus coilovers system at minimum be in the same range of performance. You can go with the SS springs and Bilstein B6 , which will be a bit better then the 1LE if you have the other suspension upgrades.
