I've never seen this amount of consensus in a car forum in my life, and I don't ever expect to see it again. It's uncanny how just about everyone describes the level of improvement in almost identical ways.

A good number of people have asked about tire wear using the DSC recommended alignment settings.

A week ago I had new MPSS ZP tires installed on my 2017 C7Z. I ran the original OEM tires with the DSC TRACK alignment since the 500 mile mark. I had the DSC TRACK alignment done at the same time as the 500 mile oil change.

My rear tires wore exactly even, inside to outside. No variance at all.

My fronts were down to 2/32 on the inside and 5/32 on the outside. A variance of 3/32. Very acceptable for me and the way I use the car. I'm willing to give up some front tire wear for the better performance realized.

FWIW, I didn't do any track days with the TRACK alignment. All street miles, however, rather aggressive street miles.

If you want maximum tire life I suggest you have the DSC TRACK settings on the rear and the DSC street/track settings on the front.

How many miles did you get out of them?

Yes, they were obviously very aggressive street miles.

Hey Rick,

If you're not tracking the car I'd think you'd still get better street performance with less camber. What you gain in cornering you're losing in braking. I'd bet if you dialed things back to -1.5 you'd wear the tires more evenly and never notice the difference on the street.

I'm running -1.5 at all four corners and the tires are wearing evenly despite both street driving and track driving. I was going to increase the neg camber but it doesn't seem necessary at least with the super sports.

Alex, Im running -2.0 in the frt and 1.7 in the rear with -.05mm of toe in each corner. I have 5k miles on my super sport. I have maybe 5-10 track laps on them. I live in a highly congested area balto/wash that the speeds are way lower due to traffic. I love to turn off traction control and hang the back out its the child in me and my tires still look like new I have not measured them. What kills the tires the most is high speed more than the camber. Plus when the chassis gets really good tire wear is generally pretty good the better the setup the better the tire life. I may have an edge over you guys I have a completely different damper on my car and it is quite possible it contibutes to better wear. On the mag shock you really have only low speed control there is no shim stack on my Tractive shock I have a high tech piston developed in the race program and a complete shim stack. What this does is givea way better tire contact higher grip and more than likely greater tire wear. the ride in my car is the best of any sports car Ive ever owned and the gip level unbelievable.
Have Fun

Thanks for the info/data. I will be tracking the car which is why I have the track settings with the fronts at -2.0. Additionally, I wanted to acquire some wear and performance data with the track settings on the street.

I'll be on track next Sunday with the new tires and will closely measure wear and tire temps. Based upon what I see and your results/comments I may very well go to -1.5 on the front. I think you might be correct that it will be a better setting for my usage.

It will be interesting to see how the rears wear with my current track settings on the track. As mentioned earlier they wore perfectly when subjected to aggressive non-track driving. They might not wear as well when driven at 9/10 on the track.

Your willingness to share data/results is one of the good things about this forum. Not too many people driving the cars hard enough to generate and acquire this type of data which is needed to make informed/educated decisions.

I've never gotten over 7,500 miles out of a set of tires on my C6Z or modified C5. Apparently I'm going to be getting even less out of the C7Z.

I should note I very rarely drive my cars in town or just cruising around. I don't use it to go out to dinner, run errands, etc. When it leaves the garage it's going to get driven.

On a lighter note, just for the hell of it I went to Discount Tire to see if I could get some help from Michelin on new tires under their 15,000 mileage warranty.

A full set of new MPSS ZP at DT was $1,750. Michelin was surprised I only got 4,700 miles out of a set and said maybe I got some out of a "bad" batch. I said, yeah, that must be what happened....

They stood behind their warranty and paid $970 towards the new set. I paid $780. Kudos to Michelin.

Rick

Our tires have a 15k mile warranty?

Yes. Actually 30k mile warranty. However, since they are staggered (i.e. 19" & 20") the warranty is cut in half to 15,000 miles.

Also, if there is more than a 2/32 differential across the tire, inside to outside, the warranty is void.

Discount Tire (DT) measured my fronts at a 3/32 differential so they said Michelin wouldn't do anything for the fronts. DT also only offered a 50% discount on my rears which wore evenly.

I wasn't happy about this so I called Michelin directly to discuss in a cordial manner. Michelin ended up offering to pay 50% for the fronts and 60% for the rears. One phone call saved me a bunch of money.

Michelin actually should have paid ~69% (i.e., 4,700/15,000 = 31%) for my rears as the warranty is prorated. However, since they really didn't need to do anything to help me with the fronts but paid 50% I wasn't going to squabble.

Did they ask about usage? I know you said you don't track. They must void that warranty if you do a track day on the tires.

Never asked. And for what it's worth I'll track the car on a regular basis. However, I got it in late October and it's been a bit chilly to do any track days.

Matter-of-fact, I'll be on track next Sunday.

I'm actually sort of proud. I think I was the first forum member to ever track a C7Z. I was one of the first to take delivery of a 2015.

I love seeing these reactions. As I've said several times before, it's hard to believe until you experience the difference in your own car.

Default Re: Dsc?

I'm following this thread, b/c, I'll only accept/buy a C7 with MSRC.

Now for the stupid Q: Does the DSC system, take over and enhance the existing magnetic ride system's performance/capability?

Whereas, the DSC, is the replacement brain, of the MSRC's brain, if you will?
