If you had actually understood, then the fact that the SS with the lowering kit ran quicker times on the track than it had with stock suspension should have sunk in. Regardless of whether you think lowering springs are for looks, THIS kit that I was talking about was tested by GM to improve track performance.

I doubt that the lowering - taken independently of any spring rate and damping increase - provided much of that improvement.

That the lowering springs were a bit stiffer, sure. The same stiffness springs could have been provided at 10mm lower, or not any lower at all, and I doubt there'd be much difference (and the lower car could well turn out to be slower). Obviously the much firmer DSSV kit isn't trading on the amount of lowering for its performance improvement.

Chevy realizes that lowering sells mainly on appearance and that people will go at least to the 'more' part of "if some's good, more's better, too much is just enough" without having any clue about where 'too much' begins.

Making lowering springs somewhat firmer is something you 'd do just to keep the car from hitting the bump stops as often, and from there you'd have to specify a bit more damping. In which case the handling improvement might only be a side effect, strictly incidental.

I’ve seen it a few times. But then, I live in Detroit and know a number of people on the Camaro and Corvette teams, so there’s that. Here’s a video I shot at Woodward Dream Cruise. I think this is the same setup that goes to the dealership road show.

Seems like you misunderstand as well. I was talking about a specific GM kit that produced quicker lap times in GM's testing. You are conducting a straw man argument with this, because I certainly did not say that lowering alone was the performance gain.

That specific GM lowering kit did more than just lower the car, and was tested in conjunction with a specific handling kit rather than separately. I'm afraid you didn't even try to separate the effect of lowering (by itself) from the effect of increased stiffnesses in the lowering kit, and you completely ignored the effect of the separate handling kit. By your omission, most people are going to read "the SS with the lowering kit ran quicker times on the track than it had with stock suspension" as crediting the lowering alone. You may not have meant it that way, but that is the way it'll be read.

People already believe that more lowering is better than less because real race cars are lowered, so if they lower their own cars to look like a race car they must be getting a big handling improvement in the process, right?

Wrong. It doesn't work quite that way, so what I'm trying to do is get people to step away from directly associating lowering with handling.

Which I suspect was oldman's intent as well.

I feel safe in Norm's hands.....
Go back and read what 6speedhyperblue has posted. This is an apples to watermelon comparison. You basically keep saying it is the eLDS and geewiz that makes the 1LE faster but discount the fact that the test is using lowering springs and dampers for lowering springs. YES, IMO, a set of proper road race springs and dampers would close that 2 second gap PERIOD.

The DSSV package did not have the 1LE tire = FAIL
The DSSV package did not have the ZL1 - 1LE tire = FAIL I know which car I want to race....


The DSSV setup, probably WAY too stiff for the stock SS tires, still I admit that I'm surprised, but this is only one course over one day. The DSSV can be setup for 1.5 negative camber at the track... was this done on their test? doubtful.


GM did not compare the bolt-on (complete with MRC) 1le to the real 1le so we have NO IDEA what the eLSD and geewiz adds. Probably less for an experienced driver.

GM since they are only marketing what the sell and make no doubt about it, it was all done for marketing, they don't have a passive damper for the 1LE spring. So what would about a bolt-on 1le with dual damped adjust Konis do against a real 1LE?

I'm back to the garage now putting in my forged engine into my M6 Camaro. I am thinking about what needs to be done to put the M6 into a 2.9 second 0 -60 time with street tires on a normal road. Either 100 wear 888R or 240 to 300 wear maybe a PS4s. For sure I need to do it in one gear as the shift alone would put me back into the 3s. ZL1 trans would do it, don't know if I can find and fit just the 2.29 1st gear. It also looks like a 7200 RPM fuel cut would do it.... There will be C8 on the street I don't want them to catch the oldman napping.

No kidding, the way that you keep going with your straw man, it looks to me like you are letting yourself get wrapped around the axle because the kit happens to be called the 'lowering kit'. You need to focus on the 'kit' part instead. Pretty simple, GM offers the 'lowering kit' for cars that don't have MRC, whereas cars with MRC can use the 1LE springs with a recalibration of the MRC if they are model year 2017 and newer. 2 solutions from GM for lower/stiffer springs with an accompanying adjustment to the dampening.

Test car was non-MRC so it had the 'lowering kit' which is springs and shocks. MRC car 2017+ could use the 1LE springs with MRC cal. My point was that thinking the 1LE spring with MRC is 2 seconds faster than the 'lowering kit' springs and revalved shocks seems pretty far-fetched. So then you have to question whether the 1LE parts/features that cannot be added later (eLSD and PTM) is making for a difference in lap times. My overall point on his hypothesis was, you cannot truly make an SS into a 1LE after the fact, so the comparison that he had in mind won't work.

So why do you think that GM decided not to call it a "street handling kit" instead?

Items for sale are normally labelled in a way that indicates their primary intent. Calling this a 'kit' does not change that, only means that you're getting more than just the springs. Does it improve anything else, like handling? Sure. But that doesn't change the kit's primary mission.

Availability of the ZL1 1LE Handling and DSSV kits (specifically noted as being preferred for autocross) makes your straw man accusation go away.

The Z06 is going to one sick car! This is going to put super/hyper cars on serious notice!
