You can drive a base SS w/ ZL1 1LE suspension kit alone on base SS wheels/tires faster than an SS 1LE? I doubt it.

Add the ZL1 1LE wheel/tire kit or even the SS 1LE wheel/tire kit and I'd believe it.
I think that's part of the problem with this test...

All the cars should be on the same tires.
Ideally 2 tests each - one with stickys, one with regular tires.

Individual Part Numbers ??

Does anyone know what the individual GM part numbers are for the pieces in the SS lowering kit (shocks, struts, springs, nuts, bolts, washers)? It was asked earlier in the thread, but I'm guessing it got lost in all the track time conspiracy theories

Looking for the parts in the non-mag, coupe, 1ss kit (84203549).

^ This thread contains seriously high quality info. I agree, the moderators should clean up this thread. Why would the Camaro team risk extending an extraordinary effort in the future, only to have it polluted with negative feedback?

Part number is 84225254 from here https://www.chevrolet.com/performanc...aro/suspension, you'll have to do some digging to find the individual part numbers.

It's likely even more basic than that. Expecting 1LE-levels of cornering & handling performance from 40mm narrower (and taller profile) tires on 1.5" narrower wheels - with any GM approved-for-release suspension - sounds unreasonably optimistic to me. Even if all of the tires were the same make & model.

On a different note. My 2012 RS V6 was a track beast (pic below), Mike can attest to this. he was there at those track events. It had BMR 3 way adjustable suspension sways, and BMR lowering race (track) springs. Goodrich G-force tires on the 20in OEM RS spokes. Muffler delete, Air intake, Vitesse throttle controller, Stock OEM shock (FE2). We had a race driver at one of our Camaro club event several years ago, and he couldn't upset it even when he hit the apex curbs. It would lap Texas world speedway in the lower 2 min times.
I traded it for the new 6 gens, left it stock. Took it to TWS again where ran more consistant times, only 3 secs quicker than my more modified 5th gen, of course, we know why. But it was phenomenal to just buy a stock car take it to the track to do better than the one I spend thousands on to run on the Road course. Btw, this was also a V6 (auto). the previous car was a manual. The only complaint was that the auto would heat up after the 6th-7th lap and I would have to bring it in.

Has anyone added the ZL1 1LE spec handling suspension kit (p/n - 84352119) IN ADDITION to the lowering upgrade (84225254) and sway bar upgrade (84242386) on their SS? I would like to know if adding that kit would reduce the benefits seen with the lowering and sway bar kits or add to them. Yet another test set up I would love to see team Camaro tackle (or someone from our community).

Given some of the discussion on this thread, I'd be a little worried that this kit may stiffen things up a little too much, and make the car a little less road friendly, or was that more a result of the DSSV dampers.... I love a very stiff suspension feel (responsive, communicative), but don't want to lose road performance since that's where my Camaro will spend most of its time. I have some fun autocross and track time planned, but more just so I can drive the car like it was intended vs. part of a competition circuit. If I make it so stiff that I am losing traction on the imperfect roads of New England, it isn't a good trade-off for me. I am fully caught up in the add-on phase, and may need to be talked off the ledge before I make my car less fun to drive vs. more fun.

I'd love input from someone who has actually done this combo, but also fine with theoretical discussion.

I may be wrong, but I think forum member glenB was looking to install that combination: https://www.camaro6.com/forums/showp...6&postcount=16

The nice thing about the GM kit (spring/shock/swaybar/link combo) is that they developed it as a package to perform with track times to back it up and it's a box you can check off when ordering the car. Seems like a proven and safe combo.

If you start mixing and matching different parts, you could easily make things worse. I think you really need to be willing to go out and track the car enough to find the deficiencies, then make needed part adjustments to address them. This obviously would require time and $$ to optimize (track days, trial and error on parts to optimize, etc). GM's got the engineering budget to go off and do this optimization at multiple tracks.

While the SS + handling/lowering kit is an attractive option, at some point if you plan to keep upgrading it might be better to just start with a SS 1LE that's fully sorted out from the factory.

I really wanted to go 1LE, but I wanted an automatic. This will be my daily, so traffic and all else pushed the SS auto.

I already had the dealer install the lowering kit and sway bar kit before taking delivery. Only other thing I am definitely planning is the solid rear cradle mounts. Iíve been considering the ZL1 kit too, but donít want to throw the car out of whack. I do plan on driving it a lot before doing anything beyond what is already done so I get to know the car and itís limits. But I do want to hear from folks whoíve already done it so I can pay attention when Iím driving mine to see if I notice issues they say the ZL1 kit would fix. I really need to find a local club to hook up with for some track days. I canít wait to start playing with the car!

Corvettes of Massachusetts.

But SCCA (Track Night in America), Hooked on Driving, and I think Chin all run events on various New England tracks. The tracks themselves may even host their own track days.

I'm sure neither Al or Mark will chime in on this one, but I would really love to know the importance of the MRC calibration. I would order the lowering & handling kits for my '16 mag ride 2SS today if I knew how they would perform without the cal as I am sure that it will never be available for '16's. There has to be someone out there who has done this. I would buy in a heartbeat if I someone could provide obective evidence that the kits will benefit a car with the standard MRC calibration. I already have standard ZL1 wheels & tires and plan to do the 6 piston brakes at some point in the not too distant future.
