CHEVROLET TRACK ALIGNMENT PDF?

[htron435]

Does anyone have a pdf copy of the original track alignment tips/suggestions/settings for the 13-15 1LE? I saved one for the Z/28 but I haven't seen one for the 1LE. Looking for alignment settings for an unmodified car with stock Goodyears. Thanks in advance.

Are you talking about the old Pedders info? I think I have that somewhere.

The link to the GM specs is now defunct. Here’s the pedders and pfadt track specs:

https://www.camaro5.com/forums/attac...8&d=1410280290

And here’s the GM text for the Z28:
3. ADJUST THE FOUR CORNERS
TIRE AND WHEEL ALIGNMENT (OWNER’S MANUAL: 9-10)
The summer-only tires on Camaro Z/28 require inflation and pressure adjustment when driving at high speeds on a track (where legal).
• Limit the vehicle load to the driver only with no other cargo and inflate the tires to at least 26 psi (180 kPa)

Camaro Z/28 wheel alignment settings can be set as follows for increased handling and performance:

FRONT

• Remove the spring spacers from the front suspension and place them in the glove box. If the car is to be on a trailer for any reason, the spacers need to be placed back in the front springs to obtain ground clearance

• Caster: 5.9 +/- 0.50 degrees

• Camber: -1.5 +/- 0.50 degrees

• Total or Sum Toe: 0.1 +/- 0.20 degrees

REAR

• Camber: -1 +/- 0.50 degrees

• Total or Sum Toe: 0.1 +/- 0.20 degrees

• Thrust Angle: 0 +/- 0.20 degrees

Do you guys have any experience or feedback using peddlers specs for the track ? I've got a 14 1LE that I plan taking on to the track next month and I just ordered tires and want to get it aligned. Suspension is stock. Is -1.5 neg front camber about the max you can get or is that the desired amount ? Thanks

If you are going to get it aligned and drive it on the street and at the track then you would be OK at -1.5. -1.5 will be more of an aggressive camber for the street though. I'm at -2 front camber and I still get faster outside shoulder wear than I'd like. I'd like to be able to get -2.8 to -3.0 but I'll need camber plates for that. I don't drive my car on the street much so for me I prioritized track alignment over a street alignment.

So for us old guys that don't track the car and only run on the street , what the best overall alignment specs for good tire wear ?

I've been running "Pedders Agressive Street" alignment for years now and love it. I have camber plates and stock struts with Hotchkiss 1" springs and a Pedders big rear bar, also caster locks. The thing handles brilliant and tire wear is honestly pretty normal.

Thanks for the input. So are you running - .75 camber for the rear and .1 toe in on all 4 corners ?

If I recall front camber of -1 to -1.25 would be a good target for improved handling on the street without being overly aggressive on tire wear. Rear camber rule of thumb is half of the front camber. So rear camber would be around -.5. Rear toe I believe was recommended to be .12 toe IN each side for a total of .24 toe IN. Front toe should be set at 0 each side for the street. Toe in or out on the front on the street will probably wear your tires faster than the camber will. So for tire wear the Toe is probably most critical on the street.

If you're talking to me here's the Pedders specs and like I said I run "agressive street"...

Here's the factory 1LE alignment settings. When I did some suspension upgrades, I had my local shop aligned to this. It came from a previous Camaro5 thread on alignment. My tread wear is very even.
