I have a standard SS with MRC and wanted to get some stiffer springs, but I don't really want to lower the car too much. Would trying to pick up some stock 1LE springs help? If so, anyone know where to pick some up or any aftermarket springs that are stiffer, but don't change ride height?

Also, is it worth to just get the $1500 1LE package from GM installed?

I'm sure you could order some 1LE springs from GM, or maybe find some new ones from someone who took them off their 1LE and added some lowering springs. It looks like you will want to get the shocks reprogrammed for the stiffer springs.

IMO if you're looking to get the most handling bang for buck so to speak the GM 1LE kit will be hard to beat especially seeing as you have a MR equipped car. For the amount of performance a 1LE gives you $1500 in nothing. Just make sure you're using a tire that can handle the capabilities of the car. Otherwise I think you're only missing the eLSD from the 1LE from a handling standpoint. Some of those ZLE solid rear subframe bushing likely would help greatly improve the performance of the car as well.

Yeah I was thinking the GM kit would be the easiest. I'm hesitant to go with solid bushings because I don't want a super harsh ride on the street. As for tires I'm running a square 19x10 setup with MP4S.

Sounds like a nice setup.

IMO the bushings shouldn't make the ride much if any harsher. I went full solid rear bushings on my old 03 Cobra and it was one of the best things I ever did to the car. Most people who have done the ZL1 1LE subframe bushings rave about it, and claim that there are pretty much no negatives to them. Especially with the MR shocks/struts. My 1LE is easily the flattest and best handling car I've ever owned, but at the same time it's probably the most comfortable or at least best at soaking up impacts. I credit this to the shocks/struts. They take a stiff/solid ride and make it pretty comfortable to be honest.

With that said I don't have the solid bushings on my car either, just going off what others have claimed they do for the car. They aren't necessarily cheap or easy to install.

yyz springs > oem 1le springs

Yeah but getting the MRC tune with the 1LE springs and swaybars would be nice

what mrc tune? why dont you just get the dcs tune modular?

GM's 1LE package comes with a tune for the MRC to match the new spring rates and stiffer sway bars. $1500 for that package seems cheaper than mixing and matching springs, sway bars, and having to do the tuning myself.

I'm going to be honest the only ones I've seem pushing this narrative are non-1LE owners. Just saying.

I have no experience with YYZ springs so I can't really comment on how good they are or aren't, but I can tell you that OEM 1LE suspension setups work excellent. They handle excellent, are comfortable on the street, and the offer adequate clearance to deal with your typical real world obstacles.

So do standard SS springs. Why are people so afraid of aftermarket suspension? The first thing most people do is change to aftermarket exhaust and intake (Why? because OEM is not the best) yet everyone preaches OEM suspension only, it's ridiculous.

I'll chime in here. You are correct, the solid rear cradle bushings do not add any harshness.

I have had mine on for a year now. They keep the rear-end from wandering on the lateral axis. The rear-end tucks in now and takes a direct set. It is very confident inspiring.

The only negative is the labor costs. It is not a quick job. Absolutely worth it though.

What are you talking about? My last Camaro had Koni SA's, BMR springs, Hellwig anti-swaybars, a bunch of Founders pieces, MWC FLSFC's, Brembos, etc. In fact the first mod I did to my 02 besides a skip-shift elimator was my Konis. My 03 Cobra was Maximum Motorsported out. My 88 GT doesn't have a stock suspension component on it other than maybe steering components, and it's got in-floor SFC's and it's caged. And that's not including my Lightning, or my import car days. I've done this a few times. Who is scared of the aftermarket? Don't think I've never modded a suspension component before. I'm not going to buy into the aftermarket just for the sake of buying into the aftermarket which a lot of people do. I highly doubt you're just going to replace OEM 1LE springs of any variants and see improvements in one area without compromising another. If you have proof of what I saying is wrong then post it. If you have proof of YYZ springs improving a MR setup over 1LE springs, without compromising other areas then post that as well. And yes often times OEM gets it right more than the aftermarket gets it right. Not surprising seeing the amount of time and $ and resources the OEM's throw at their cars over the aftermarket companies who more just follow a narrative of, "stiffer means flatter cornering, softer means better for weight transfer. Knowing that we'll just move the spring rates around this much, throw on some shocks to help with whatever we intended these springs to be used for, run them around a road course, or at a drag strip a few times, and call it good."

Again don't think I've not ever modded my suspensions. If these springs improve on a 1LE's performance I want to see proof, and I'll be all for them if they don't heavily compromise other areas. All I see is talk on here from non-1LE owners. The reason I bought a 1LE is to let the factory get the suspension right. My 02 SS and Cobra handled better than stock on ideal surfaces, but on rough pavement they rode like crap compared to an OEM car, they were harsher, more noisy, sometimes you had to troubleshoot weird pops and noises coming from them, and they likely weren't as good as what a high-end factory offering would of been. For example I had a bunch of MM parts on my Terminator including C/O's with MM valved Bilstein Sport shocks/struts, and also the FTB solid IRS bushings, amount many other little components, and I highly doubt that car would of handled better than a factory 2,000 Cobra R.

I'd go aftermarket if I didn't have MRC. I just don't think any aftermarket suspension company has a better setup than what chevy offers either in the 1LE or their own performance packages. Also I don't really want to drop the car an inch when it doesn't end up offering any performance benefits. I'd much rather have a setup that has been engineered to increase performance by the same people that designed the whole damn chassis in the first place.

Also engine mods are easier to measure the benefits of and imo simpler to tune than the suspension/chassis.

Good to know. How much was the labor cost if you don't mind me asking? I'd rather not drop the whole rear cradle out myself.
