I dramatically improved the ride and handling on my C6Z by ditching the OEM GY F1 EMTs and going with Michelin Pilot Super Sports-Non EMTs. HUGE difference. Tons more traction (more than 30%), no more tramming, less than half the amount of howling (I can actually open my windows and no long be deafened), creamy ride quality, no more front end hopping/skipping on sharp turns...Best upgrade I could've made for $1700.

Had my alignment done today! The caster setting was done as I specifically ask. I did the MRS UPGRADE and can tell difference in touring and sport. Also had A8 upgraded in its computer plus a new tensioner belt. I pay 499 for things I ask for and GM paid 919 for their part. The car rides and shifts better!

[@HorsePowerObsessed]

Excellent! What dealership did you go to? Did they specifically adjust the rear caster? What was the original setting and what was it at when they were done?

[@curtisfish7984]

Great video; who knew Chevrolet Dealers can’t adjust the rear Caster on a C7 Corvette. Because that they don’t have the tools necessary to adjust the Caster. Can you give any idea what DSC charges to adjust the rear caster? Also any insight to changing to the DCS controller? Are there options for those of us that don’t live within driving distance of the DCS World HQ? Thanks!!

[@HorsePowerObsessed]

Absolutely there are! They sell the controller on their site and you can easily install it yourself (it comes with the same programming I have on mine). As far as the alignment its billed by how long it takes to adjust. Mine was pretty quickly done but it can sometimes take 3 to 4 hours to dial it all in properly since each individual setting changes others (caster change will throw tow and camber out, etc.) There are other shops that can accurately provide an alignment (I hope) and you could give them DSC's recommended specs to have the same thing accomplished.

[@curtisfish7984]

Thanks for your reply. I plan to provide DCS’ recommended rear caster settings if I can find someone to make the caster adjustments. Good to know I can buy and install the DSC suspension module.

[@HorsePowerObsessed]

After calling multiple dealerships and getting told that they didn't have the tool needed to align it I started looking on the forums and came across DSC. They could do the alignment and they made a mag ride controller that people liked so I figured it was a win/win. Plus it ended up only being about 3.5 hours from me.

[@gixxerrider2825]

i know exactly what you mean... wish that place was closer to me. i have another funny story from GM. my conv top sensor failed and it was stuck down. i took it in of course and they REFUSED to tell me where the manual power was. like flat out said, "we don't divulge where the manual power is to customers" he told me to go to the parts department and buy an external power unit.

Honestly before I experienced it I would have said no but after seeing how much of a difference it actually makes I would suggest it. The difference in ride quality is absolutely amazing.

You should have seen their face when I asked them to explain both print outs of before and after. They literally had zero idea the C7 issues. Later months later GM did a buy back because of the auto transmission issues they couldn’t fix. Less than 6k miles and over 6 months at dealer. Sad 😞

Unfortunately there isn't any easy way. You'll have to call and ask specifically if they know how to adjust the rear caster on a Corvette.

[@johnglynn7795]

Hello Justin, truly an informative video. Why is is that you decided to have GM perform an alignment on the rear? As far as the DSC controller; what is the cost of that unit versus the factory controller? BTW, I am delaying the purchase of my carbon fiber center console until the fall. Blue skies, Jg

[@HorsePowerObsessed]

I had GM do an alignment on the whole car because I had read that the C7's were heavily cambered right from the factory and wearing out stock tires. I didn't really want to spend 1600 dollars on tires right after buying my car so I figured I'd get it taken care of but I didn't know they were going to throw the rear caster out so badly. The factory GM mag ride update is 350.00 but you literally have no way of knowing if they did it or not. You can find this controller on the Corvette forum used for around 700 - 800.00 or straight from TPC/DSC for 1250.00.

[@kevinclark1482]

HorsePower Obsessed Was the price for the adjustment (labor) separate from the DSC controller. I was wondering if one can get the alignment done there ONLY?

[@HorsePowerObsessed]

@@kevinclark1482 Yes you can get the alignment only. It's billed hourly so if it's horribly out of whack it could be 300+ dollars.

I would highly recommend it for ANY C7. They all come out of the factory poorly aligned. Any SPECIALIST alignment shop should know hot to set the rear caster. Asking them specifically for setting the rear caster on a C7 would get you the answer as to whether or not they can be trusted to do it. If they act like they have no idea what you're talking about move on to the next option.

It would not void warranty as long as the issue you're having is not directly related to this controller. Even if it was as long as you replace the stock controller and take it in for warranty work it would be taken care of. I highly doubt you'll have any issues that are caused by this controller so I'm going to say absolutely not your warranty is not void. The controller from their site is $1290. You can find it cheaper on the Corvette form used but in my opinion it's worth every penny. Those guys down there are extremely knowledgeable and they know exactly how to take care of a Corvette.

It absolutely is! The car is literally "dangerous" on factory specs let alone what my local dealership left me with after an "alignment"

Then this needs to be discussed further. There are SEVERAL blogs stating the DANGER of these cars on acceleration. What if everybody is driving a improperly aligned car in the first place. The C8 could be the exact same way, and imagine people thinking it handles poorly. GREAT INFO AND A FIRST TO IDENTIFY A VERY SERIOUS PROBLEM THAT POTENTIALLY IS LIFE THREATENING.

[@thiosemicarbizidebenzoylal2921]

What if the C7 actually is one of the best handling TRACK cars, and Randy Pobst was given many examples of improperly adjusted cars in the first place. The ZR1 could be even faster on track than it already is. Too much speculation as to why they would release a car like this.

It's amazing to me that GM is still shipping cars brand new from the factory with stuff incorrectly assembled. This is the kind of thing that got them known as producing junk. Corvettes, in general, and certainly upper-end Corvettes in particular, are halo cars for GM - they should come new from the factory in perfect condition. I bought a 96 Impalla SS brand new and it came from the factory with an electrical short in it and a driver's door that was horrendously fit. Interesting how that hasn't changed...

I agree it is a shame. I knew the alignment wasn't good from stock so in order to spare my tires, I took it to my local dealership where they did an "alignment" for me but apparently it was pretty poorly done. It's like a different car after this alignment and the controller. 😀

The spec is north of 150 and you need 2 hands on the wrench to get that, don't care how strong you are. On my c5z I ruined a set of Kumho slicks $$$ in one session because the azzhole alignment guy did not torque any. They all moved, slicks git you bueno grip. That's when I decided to learn, buy equipment & do my own.

Wow! This news seems kind of weird to me.I've grown up having many Corvettes and to me, I have found the opposite. It has always been known by everyone including myself that when you take your Corvette in for an alignment that they have always aligned both the front and rear. I take my C6 into my local Chevrolet dealership and I have never had to even ask them to do that. In fact, I do some very spirited mountain driving once a month with some guys in the Corvette forum and they even set up suspension up for that type of driving and it handles awesome. My Brother has a C7 Z06 and they align his car front and back! So before you go around telling everybody that you have stumbled across this big huge problem that know one knows about you might want to do some more research. What are the odds you found so many dealerships that know anything? To me, that like you found a bunch of tire shops that don't know how to balance a Corvette wheel?

[@HorsePowerObsessed]

They aligned my front and rear that's not what I'm saying. They didn't adjust the rear caster and NO dealership I've found yet knows how to do it. It's very important and a well known issue.

[@jmos96]

It would have been nice if you would’ve shared the alignment specs.

[@HorsePowerObsessed]

Didn't think about it, DSC puts them right on their site for the world to see, but I'll include them here as well! bit.ly/2Zdnq8h

There is absolutely a way to check to see if the GM update has been performed. Go here: tis2web.service.gm.com/tis2web/ Put your VIN in and click Get Cal ID. Select K19 : Suspension Control Module from the list. Click Next. Select Programming. Click Next. Select With Semi Active Damping System and click Next. There will be two modules listed. Operating System and Real Time Damping. Click next. In the Real Time Damping Module, you should see. "New calibration to support performance parts and motor sport catalog customers." This is the update. There will be a part number, listed to the left, which corresponds to the model of your vehicle. I have listed the part numbers as follows. Ive made this list as accurate as possible, because I know that people may stumble upon this video, in the future, and I want them to get correct information. 84353680 (Without Track Mode Change) 2015 Z06 with Z07 Suspension RPO FE7 84353681 (With Track Mode Change) 84353682 (Without Track Mode Change) 2016 Z06 with Z07 Suspension RPO FE7 84363682 (With Track Mode Change) 84375893 2015 Z06 without Z07 Suspension RPO FE6 84375892 2016 Z06 without Z07 Suspension RPO FE6 84375894 2017 Z06 without Z07 Suspension RPO FE6 84353677 2014 Z51 Suspension RPO FE4 84353684 2015 Z51 Suspension RPO FE4 84353685 2016 Base Suspension RPO FE2 84353686 2017 Base Suspension RPO FE2 The thing you need to be absolutely sure about when getting the GM update, is that you let the car sit, static for the appropriate amount of time, after the update is completed. I got mine done about a year ago, and I cant remember how much time it was, 8-10 hours, I want to say. GM has to actually contact customer service with these part numbers to perform the update. But the process I have listed, will tell you if the update has indeed been performed. If the update has been performed, these part numbers, year appropriate, will be listed under Calibration History "Real Time Damping." Also note, unless you have the years listed above, the "Track" calibration setting WILL NOT be enhanced in the calibration file. Touring and Sport are the only modes that will receive an update. Nothing much has changed in the track setting, for these cars. The Sport and Touring modes, drivability was improved. Sport, will be a mode that you can actually drive in. Without the update, Sport is almost as harsh of a ride as track. And in Touring, rebound damping is greatly improved, along the vertical axis, I.E. Soaks up the bumps better.

[@HorsePowerObsessed]

Yup. I've seen that on the forums, but the problem is it doesn't ALWAYS work. The forum shows the same thing. Some people it updates for and others it doesn't. There is NO way to 100% verify it was applied.

[@g.dubyou6263]

I think some of the dealers are just taking money, then and just telling them they installed the update. I noticed it right away. The sport mode is 100% better than it was. And I need to find a place, out here, in California, to see where I can get the correct alignment done. Maybe we should make a thread on the forums to list places to take it that are close to you? Sounds like a good idea to me. I may start one. 👌👌👌

[@HorsePowerObsessed]

@@g.dubyou6263 I like that idea! It took me forever to find somewhere that could do it and even then it was almost a 4 hour drive!

[@g.dubyou6263]

HorsePower Obsessed and you had to get a hotel. I’m sure if I can’t find some place in Northern California, there has to be a place in Southern California, without a doubt.

[@HorsePowerObsessed]

Yeah there's one somewhere I'm sure. Just make some calls and straight up ask if they can do it. Unfortunately that's the only way to find out.

[@alsnow3582]

I'm sure they do great work but that tech doesn't think much of Corvettes.

[@HorsePowerObsessed]

Which tech are you referring to?

[@mikeeagle2653]

You can adjust all this since C4 this isnt new

[@HorsePowerObsessed]

I never said any of this was new...? Just providing my experience with the dealerships lack of knowledge with alignments and the DSC controller...

[@jmfrademartin]

That controller is absurdly expensive. Need to be half the price.

[@HorsePowerObsessed]

It could stand to be cheaper but you are really paying for the years of racing experience and R&D on it. You can find it pretty cheap used on the Corvette forum.
