    How many street miles does Spring Mountain put on every single one of their Corvettes before they first put in on their track?

    1,500

      The owners manual says no full throttle starts until 500 miles. A launch control start is a full throttle start. You don't need to wait until 1,500 miles, it wouldn't have taken anything at all to say in the manual "no full throttle starts until 500 miles and no launch control starts until 1,500" but they didn't say that. Getting up to 60 using full throttle is not a track event.

        Yeah one video I saw "jrock702" His best 0 to 60 is also around the same. And for C7 Z06 at NV/Vegas it's about 0.7 slower in 1/4 mile vs at sea level, so it's about right compared to 2.8 at sea level.

        Did instructors at spring mountain mention if their C8s have problems after all that launches from students? Or don't lower tire pressure, wait 5,10 minutes between launches etc ?
        The instructors didn't point to any problems or worries during my event at Spring Mountain. They set you up just like the manual said to, and off you went.

        They did say that this thing was so fun at launch control, they believe owners should do it every time they go for a drive. (I agree with that assessment.)

          Hi guys looking for some updated info since this thread is from Jan of last year.

          So is the snapped axle still rare for most C8 or is it common (From launch control)? I am almost at 500 miles and plan to do launch control on local streets often, probably drag strip once a month or less. (Stock 2022 Z51) Thanks for your help.
          I haven't heard of any broken axles on stock, unmodified cars other than the one possible one more than a year ago. At Ron fellows every student does 2 launch control starts in every class, and they run multiple classes every week. They've reported no issues.

          As far as 500 vs. 1500 miles, I agree that a Launch Control start isn't a track or competition event. But I also recall Tadge saying he would extend the 500 mile break-in to 1,000 miles on his personal car. Your car, your decision.

            Totally agree with this plain reading of the manual. Also confirmed by the instructors at Spring Mountain. Launches are ok at 500 miles, wait until 1500 for track days or autocross events.

              We got to do six - three from each end of the main straightaway. My instructor Darryl (who swears he has no brothers named Darryl), said GM warrantees the car for these launches, and as long as you do it per the manual, you can do as many as you want. One other point - you need to put both hands on the wheel - the thing won't go in a straight line without the driver's guidance ! It is a hoot, but you need to pay attention !!

                Quick survey: Who has broken an axle?
                what power mods do you have?
                What Tires did it happen on and treadwear rating of the tires?

                Thanks in advance for the info!
                No axle failure but thought you might appreciate this pic…My Queen named her…
