Suggestions for 2007 C6 Z06, PFADT dual coilovers, sways, Hoosier R6 295/245 on CCWs, stock bushings for now, 570rwhp.

Also run OEM size Michelin PSS on OEM wheels.

Looking to be a little conservative, -2.5, -1.25, toes? What do you think?

Thanks

Here's the Pfadt Specs:

Pfadt Corvette Alignment Recommendations
These settings are a guide based on the experience and testing of Pfadt Race Engineering.

Performance Street
Front min max
Camber (deg) -0.7 -0.9
Caster (deg) 7.5 8.5
Toe -1/16" 0
Rear
Camber (deg) -0.4 -0.6
Toe -1/16" 0
Notes
These settings will provide good performance and good tire wear

Performance Street - Track Use with Street Tires
Front min max
Camber (deg) -1.1 -1.3
Caster (deg) 7.5 8.5
Toe -1/16" 0
Rear
Camber (deg) -0.7 -0.9
Toe -1/8" -1/16"
Notes
These settings will provide good all around performance. The tires will wear the inside edges
in street use and the outside edges on the race track. This is a good dual purpose alignment.

Performance Street - Track Use with Race Tires
Front min max
Camber (deg) -1.6 -1.8
Caster (deg) 7.5 8.5
Toe -1/16" 0
Rear
Camber (deg) -0.9 -1.1
Toe -1/8" -1/16"
Notes
These settings will provide great track performance. The tires will wear the inside edges
in street use, and the car may tend to grab the lanes of the road. Race tires will wear well
at the track and provide high levels of grip. This alignment is compromised towards track use.

Dedicated Track Car - DOT Tires, poly bushings
Front min max
Camber (deg) -2.8 -3.0
Caster (deg) 6.5 7.5
Toe -1/16" 0
Rear
Camber (deg) -1.5 -1.7
Toe -1/8" -1/16"
Notes
These settings are a good starting point for a car with polyurethane or stock control arm
bushings. This alignment requires DOT race tires to function appropriately.
This is a starting point only, testing and monitoring tire temperatures and pressures are required
to optimize any setup.

Dedicated Track Car - DOT Tires, Spherical Bearings
Front min max
Camber (deg) -2.4 -2.6
Caster (deg) 6.5 7.5
Toe -1/16" 0
Rear
Camber (deg) -1.2 -1.4
Toe -3/16" -1/8"
Notes
These settings are a good starting point for a car with mono-ball or spherical control arm
bushings. This alignment requires DOT race tires to function appropriately.
This is a starting point only, testing and monitoring tire temperatures and pressures are required
to optimize any setup.

Dedicated Track Car - Race Slicks, Spherical Bearings
Front min max
Camber (deg) -3.0 -3.2
Caster (deg) 6.5 7.5
Toe -1/16" 0
Rear
Camber (deg) -2.0 -2.3
Toe -3/16" -1/8"
Notes
These settings are a good starting point for a car with mono-ball or spherical control arm
bushings. This alignment is designed and tested with race slicks, not DOT tires.
This is a starting point only, testing and monitoring tire temperatures and pressures are required
to optimize any setup.

Jim thanks a lot very helpful perspective.

All the credit goes to Pfadt for making their recommendations available. I've used the settings down to "Dedicated Track Car - DOT Tires, poly bushings" which is what I'm running now. I would share those results with you but I've been plagued with tire failures this year and don't have many miles on the new tires and have not pushed very hard.

Jim has good info!!

Here's a link to Pfadt's site with a pdf of that alignment data:

http://www.pfadtracing.com/blog/wp-c...-9.12.2011.pdf


NOTE what it says at the top of the page!!

Most alignment specs use a negative # to designate toe-out, but no problem as long as you know what you're dealing with.

Also, Pfadt recommends toe-in up front, even for their aggressive track alignments, whereas many racers like a touch of toe-out for the front for better turn in, and slight toe-in at the rear for better handling when getting on the power accelerating out of the turn.
