Apex Competition's 996 Carrera 2 Project Car

So what's this all about? It's about the impressive Porsche GT3 Cup cars that we can't drive everyday... so why not take an affordable 996 C2 and modify it to arrive at a semi-comfortable yet formidable weekend club sport toy... One that can still be driven to and from the circuit and even everyday!

Track Alignment

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°

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
Caster: 8° +/- 30'

Rear axle:
Toe total: 32’ +/- 2'
Camber: -2.4°
