Add me to the list of those who are extremely happy with the mag ride update! I’m so pleased that I’m cancelling the order I placed for non-run flat Conti’s. My reason for switching to a non-run flat was purely for the improved ride. It feels like a different car since the upgrade. I prefer Sport Mode but the marginal roads around Central Indiana caused teeth chattering, even when I was in Tour Mode. It was so bad that I seriously considered getting rid of my beloved GS. It had gotten to the point that I was afraid to drive outside of my work commute route, where I was able to memorize and avoid the road hazards. These road hazards were no issue in any of my other vehicles and I would otherwise never have even called them road hazards, but for the GS. I love my car again!

Tour- Significant improvement in daily drivability, more “plush” with routine bumps better absorbed AND the car feeling more planted. This would seem counterintuitive when the words plush and planted being in the same sentence but that seems to be the case. While bumps and road imperfections are better dealt with, the car doesn’t seem floaty. In truth, the car seems more predictable in turns (i.e. off-ramps and the like) since the imperfections are better absorbed without upsetting the suspension. So far, this is the biggest improvement for me. Sport- Ride is less punishing on the road but the steering “seems” heavier than before as a positive. Feels more responsive in general (thinking due to steering), while not feeling “nervous” and “twitchy”. The Sport mode is more taught overall but at the same time more usable in routine driving…

In Tour mode the car felt like it skimmed over the bumps confidently absorbing the undulations and filled potholes and the steering felt perfect. SR 12 is an extremely bad road as it lies under the level of the levees and has expansive soil under the structural section of the road. It is almost like a roller coaster in some spots. So, it was easy to tell the difference between driving to the dealership and then from the dealership after the MRC update.

Tour Mode – Plush and absorbs the bumps a lot better than stock. Road imperfections do not shake the car and make it hop anymore. Word here is ‘compliance’ with road information that trickles through. Sport Mode – Sport mode made the most difference for me. In Sport mode the chassis and damper are in perfect harmony. No disconnect. Verdict – Worth every penny. The key thing here is the Chassis and Damper are in sync in any mode. Thank you GM! This steering junkie loves his car more than ever before.

I just got back from a hundred-mile trip home, so I could tell if there is any change. Let me tell you it was like driving a new vehicle. For the first time I could leave it in sport mode on I90 in MA. The biggest difference was that I could drive on the interstate in sport mode without rattling my teeth out. All the bumps and cracks in the road have smoothed out and the steering has some real feel of the road. In tour mode it was smoother than my CTS. This upgrade has to be better for the vehicle not to be beat on from every bump in the road. I have paid for many improvements over the years for all of my vettes. But this was, by far, the best improvement. For those of you that haven’t felt any difference take it back to the dealer because something didn’t take. This is not a placebo effect, there is a big difference.

Was it worth it? My goodness, I just got a new car! The first thing I noticed was that steering input was immediate and precise. The thumps were gone, same run flats so it is not tires. There was so much improvement that I actually went to the Sport Mode, something I almost never did before on the back roads, nor almost any road in Pennsylvania. It was great; I was actually enjoying the Sport Mode and kept it there for almost half our outing. I did some roads that I know well, so well that I have memorized the humps and road patches. I now have a Z-51 with all the added capabilities but with the pleasant ride of a base touring car. Conclusion, worth every penny.

The car now just feels much more stable and connected to the intent of my steering regardless of road condition. I put a lot of highway miles on mine and always felt I could never fully relax in touring over 80 mph. Not anymore! I pushed it in Sport and Track on some twisties a couple days ago and everything just seemed more planted and willing to take throttle. The steering input are without doing something unexpected as well. Well worth it guys….

All I can say is “wow” when it comes to the comfort aspect! The car is now handling sharp impacts and rough roads better than it ever has! I intentionally drove it on a certain lane on a concrete road near my house that is frankly horrible from all the construction trucks driving on it. I will typically avoid it whenever possible. The improvement was night & day; the car stayed planted, felt smooth, and wasn’t jumping all over the road anymore.
Corvette forum member: Patches
I am so happy with the change in how the car feels now. I’ve had a few weeks of commuting to get the feel of the new calibration and it has made a big difference in the feel of the ride. The harshness over rough roads in Tour mode I used to cringe at is gone. The change in Sport mode is similarly improved. This is truly a significant change in the performance of the system and exactly what I was hoping for. Finally, a mag ride setup that can handle with composure most of the crappy road conditions I encounter here in SoCal.

The suspension tune upgrade has been great. So much more composed yet not out of character – its still a corvette. Very nice. Time and money well spent.
Corvette forum member: hcvone
Had this done to my 2017 Z06/Z07, the difference was like getting a new car. It went from bone jarring in sport mode to being able to drive the car on any road in sport mode. The were roads I would avoid because they would chip your teeth in tour mode. Now tour mode makes those roads feel like you are in a Caddy. The best 350 dollars I spent on the car to date.

What I didn’t expect was immediate, instant-gratification. On my ride home I felt a noticeable change in ride quality in Tour mode. This is all good because I now feel like I have two suspension options for the street (Tour and Sport) whereas I always left it in Tour (or Eco) before.

On the 10 mile mostly freeway drive home from the dealer it did feel like the car was smoother in Tour. The car sat until today. Today I did my normal 40-mile round trip to the Club. I normally run in Tour because the route is really too rough to comfortably run in Sport. At about 10 miles or halfway there, the Tour setting had been so smooth that I switched to Sport. My butt o meter says that Sport is now more comfortable on normal roads at normal speeds than Tour was before the tune update. I ran in Sport all the way home and even tried to hit some of the manhole covers that I normally avoid, and the car is just simply much smoother. I am sold.

I could tell the difference in the suspension calibration immediately. Sport mode took the bumps like the original Tour mode, and the new Tour mode was like driving on a cloud. The new Sport mode calibrations takes bumps like the old Tour mode. The new Tour mode is freaking awesome. There is no bounce when coming down the back side of a hump/bump. I was hoping to keep the car in Sport mode most of the time now, but the new Tour mode is too nice of a ride not to use during normal highway driving.

Touring mode is a vast improvement and feels perfect for cruising and regular driving. I never used Touring before because it felt like a base, non mag ride suspension, floaty without optimized damping. There are no more noticeable bouncy low frequency oscillations. They’re slowed way down during compression and the car settles softly. Overall ride stays very flat and compliant. It removed pretty much all high frequency bumps or rough road feel through the chassis. It has a very plush ride quality, if that makes sense. Cruise-a-licious indeed. Sport mode feels slightly softer overall. It’s more noticeable in the rear end during acceleration. Overall ride quality is improved in that high frequency oscillations are a touch more dampened without removing too much road feel. The overall planted feel is very similar, but it feels more optimized for more general driving. I only used Sport mode before, but now leave it in Touring mode 90% of the time. Once I get into twisty sections I switch over to Sport as there is less deflection through the corner and reacts more quickly to bumps. It’s easier to control once your foot is down.

I am one happy camper!!!! Like everyone else, well worth the $350. The car in tour seems much softer over bumps. In Sport mode it seems much more planted and steering gets nice and tight at highway speeds. Did an aggressive move on the highway and the car seemed like it was on rails. I highly recommend this upgrade.
Corvette forum member: Flo
I like a lot the new feeling it gives. The car is much better controlled, and the feedback from the road is better too. It’s really impressive as if it is a new car. No regret for having done.

Had my ’15 Z51 done a week ago now and the improvements were noticeable immediately. In my opinion, it is definitely worth it! I drive in tour primarily and the ride is definitely firmer (in a good way) yet smoother and is much more comfortable. The interstate concrete seams are much less noticeable. I have switched to Sport several times and the ride in sport is firmer yet smoother as well.
Corvette forum member: gpotski
Just had my 2015 Z51 coupe upgraded, and the ride is much smoother. Sticks to the road better in Tour, and Sport is also absorbs road bumps better. Well worth the cost.
Corvette forum member: 2K14C7
Like others have stated it’s a little hard to explain exactly how the difference feels but there is less “jolt” on bumps and a smoother overall ride in Tour and Sport.
Corvette forum member: bufalobob
I live in ski country and some of the roads can be quite rough. Where I had to use touring I now use sport. Less harsh on potholes & washboard.
Corvette forum member: c54u
For me, the car feels better planted on the road and does not skip over imperfections giving it a more refined ride. The ride has noticeably smoothed out.
Corvette forum member: NicD
I was finally able to update my magnetic ride control with the latest GM performance calibration a few days back. Gone is the floaty feeling in Tour mode yet it is still nice and soft. Sport mode is still firm but absorbs the bumps in the road better. Overall, I can say that for me it was worth it.
Corvette forum member: dashotgun
My review of the difference is that tour is much smother, less hars,h and seems more precise. Sport is also less harsh, you still have good rood feel but it does not punish you to reveal the surface of the road. I have been flipping back and forth from tour to sport. I almost never drove in tour, but it is so damn comfortable now, may leave it in tour for general non sporty driving.
Corvette forum member: Puttnutt24
I felt the improved suspension as soon as I let the clutch out. I couldn’t be happier.
Corvette forum member: Asleep@thewheel
The new MRC update made it a different car. At slow speeds or in Tour mode it rides like my 5.0 Genesis. If you get fast, aggressive, or go to Sport/Track mode it feels like it turns even better. Make no mistake, I am not a pro driver, but this upgrade makes the car feel smoother when cruising and more precise when you push it.
