Track alignment for DD?
Group
I usually do about 4-5 track events per season. I have a Z06 with the Z07 package in order and this will be my first vet.
For the guys tracking their Z, do you keep the OEM alignment for track days, or follow GM's recommendation for track alignment?
Between track days do you revert back to "street" alignment? Also can the car be driven with track alignment without eating out the tires?
Thank you in advance for you answers.
Cheers

I have left mine on the track alignment. Cost me $175 to get it aligned thanks to them having to reprogram the steering system. Yea you will love how much better it handles with the track alignment. I haven't seen any more wear on the tires I am watching them closely. If its going to wear on the street it will indeed be on the inside edge of the tire so keep a close watch on that. Also a interesting point I found while getting the alignment. My car came from the factory with a bad alignment. I will post a pic of the before and after setup I am running.
Also note i did not lower my car.

Lastly, I'm wondering if the M7 car that Randy Probst drove in the recent MT GT-R Nismo versus Z06 article didn't have a bad alignment since he stated that the car felt unbalanced. That has been the only time I can remember a review saying the car wasn't really 'easy' to drive fast on a road course.

If you aren't having any noticeable increase in tyre wear running the track alignment 100% of the time, I'll leave mine in that alignment all the time also.

Would love to hear more about what you find re: 18" options. Do you have the CCBs?
I plan to keep the car on the track alignment. I've done this with all my previous cars as it feels so much better. You can mitigate inner tire wear a bit by adding a few pounds of pressure to your tires and keeping them on the high end for street driving.

agreed. Something just wasn't right about that description. As you can see from above my left front was a whole 1* off on camber from the factory. After I had the car setup with the track settings I was amazed at the difference. Gives a whole new meaning to point and shoot car. Plus I should get at least 6 more track days on these tires. I have the Super sports though were you have the PS2's. Most have said the PS2's only lasted 2 days on the track. That will get expensive quick. I am seeking some 18" rims and will be getting some race slicks for my track season.

Whoever set up your alignment have no idea what he is doing! You have toe out in the rear! It is good only for drifting, but if you gona use your car at the race track it is dangerous! Camber settings are fine, but you need to to have toe in in the rear if you want to have a stable rear end at the corner exit.

Yes with electronic steering they had to hook it up to a computer to get re centered is what they told me. I saw them plug it into the obd port so guess they did something.

OP I run my track settings on the street and have been for years, it will wear the inside a bit. I usually heat cycle out my tires before wearing out my tires so I don't worry too much about it.

Local shop BPA performance. They have many race cars and are even involved in the continental tire racing series. They know more about race alignments than most likely anyone. He did say something about he had to grind a cam bolt of some sort to get it to turn enough. I had the car at road atlanta and it handled incredible. I included the above print out to show what the car was stock and what they took it too. They went over this car with a fine tooth comb before my track event.

Really. Figuring on how they have multiple track cars they set it up according to GM's track specs. Rear per GM: Mine as they set it up: Camber -2.0* -2.0* Toe 0.05* 0.03 on Right 0.02 on left Not sure where you are saying they got it wrong.

In your print out it says 0.05 (not -0.05) that means 0.05 degrees toe out
May be that's the way they print it out, but I never seen anybody who marks toe in as positive figure. I would ask them to confirm it is toe in not toe out.

If they are correct and they put toe in, it is incredible that your car came from the factory with toe out in rear(according to your print out)

May be I was wrong with this one, but a saw a lots of shops that don't know what they are doing and can put toe out instead of toe in. I hope its not your case.
