Now that the GT3 wheels and track tires have been on the car for a while it was time to take a good look at the alignment. So we headed over to our friend’s shop who has a hunter machine. After taking a look we discovered the rear toe was off and that the camber settings would have to be adjusted to keep from destroying the R-compound Pirellis on the track.
After reviewing a number of setups and especially looking over the GT3 recommendations from Porsche race engineer Roland Kussmauls, we came up with the following track / street compromise.
Front axle:
Toe total: +4′
Camber: -1.7º
Caster: 8° +/- 30′
Rear axle:
Toe total: 33’ +/- 2′
Camber: -1.8°
Rear axle:
Toe total: 33’ +/- 2′
Camber: -1.8°
These are our starting points. Depending on the performance on both street and track we will adjust from here as time goes on.
If we were going to optimize for track use we would go with Roland’s Motorsport recommendations:
Front axle:
Toe total: +5′
Camber: -2.5º
Toe total: +5′
Camber: -2.5º
Caster: 8° +/- 30′
Rear axle:
Toe total: 32’ +/- 2′
Camber: -2.4°
Rear axle:
Toe total: 32’ +/- 2′
Camber: -2.4°
