"ZL1 1LE Only

Change the engine oil to Mobil 1 15W-50. Change the engine oil after four hours of accumulative track usage. After track usage, the oil must be changed back to the engine oil listed in the “Engine Oil” section of the owner’s manual."

I agree on getting high temp DOT4 brake fluid.

Rotate your tires halfway through the day. I have heard GSS wears one of the fronts quickly compared to larger tracks. This is usually not needed at larger tracks...maybe rotate fronts at the end of day 1 for a 2 day event at a larger track to help tire life a bit.

You may want to replace the 4 rear alignment bolts for peace of mind. Also give them specific written instructions on the amount of camber and toe you want front and rear for best results. ZL1 1LE has 2 front camber adjustment points so you may want to specify which one(s) for them to use.

Thanks for the info.
I actually have the newer 0w-40 ESP oil which I understand is supposed to be safe for street or track.
If I'm wrong, please let me know.
Hopefully this chevy shop will get the bolts and alignment done correctly.
They stated they have done several ZLE race alignments.
And in general were MUCH more knowledgeable about the whole thing than any of the other ones I talked to.
The other two dealers were absolutely clueless about it.
