The Z51 option is very appealing to me even though it is very unlikely that I will be tracking the car. The performance elements combined with the appearance pieces makes a very compelling package for the price. I love the e-diff, the wheel, the spoiler, and you can never underestimate the benefits of the coolers.

The rotors on the Z51 are slotted. Can these be turned like a standard rotor or are they a replacement item only? It is one of those ongoing maintenance things that I am considering when weighing the Z decision (like the 9-10 quarts of synthetic for the dry sump). I think if the mag ride was offered apart from the Z package I might consider the base package, but I am sold on that technology to better handle the crumby roads here in central PA.

I know, it is not a big $ thing by itself, but it is better to consider the whole picture with complete info.

Thanks. This seems to be a very informative forum with a bit less berating of people legitimately looking for information or asking a question that may have been asked before. Looking forward to learning and sharing here!

I don't think it's something I would do though there are many who claim it's not a problem as long as you only take 3/1000 or less. Come to think of it, I haven't had a rotor surfaced in 20 years, I just buy a new one if needed. Unless you are tracking the car there is no reason rotors can't last 75,000 miles and the stock pads are not as hard on rotors as old school semi metallic pads. Switch over to carbon ceramic pads and you probably will never replace or resurface the rotors.

Thanks folks. I probably will change to ceramic pads as you indicated if nothing else than to reduce dusting. Thanks for the quick replies and the welcome to the forum!

Jeff, welcome aboard. I've never had a problem with any slotted rotors I've owned and I've never had any resurfaced. I watch the pads close and replace when needed.

The problem with a standard brake rotor lathe is the slot or hole when encountered with the cutting tool will "hop" each time it crosses the slot/hole and make a smooth true finish difficult. The correct way is on a surface grinder as a flywheel would be resurfaced. Not cost effective, so I agree with mjw and others. Don't let this dissuade you from such an awesome car!

Using proper method I don't think a couple of cleanup cuts in the rotors will be an issue.
I mic'd up my non Z51 front rotors they're 1.465 nearly 1 1/2 inches thick. rears are 1.065
Plenty of meat on those rotors. Maybe Z51 owner can check thickness
