lowered car with 18's alignment specs...
 

Can you lower a car and get the rear toe set to zero with the stock end links? or do you need adjustable ones?

I have adjustable ones on there now and adjustable upper control arms with pss10s but i don't really want so many hard parts on the back unless i need it to make to tire wear evenly..

Im about to take it in for an alignment and have them set the rear to zero rear toe and the camber to -1.0-1.2 but i only want to do it once..

Anybody??... does anybody actually work on their cars any more???!!!!

GT3 street alignment:
Rear Axle:
Camber: -1.50 degrees +/- .10 degrees
Toe: +08' +/- 05' Total Toe: +16' +/- 10' axle angle: 0' +/- 10'
Front Axle:
Caster: +8 degrees +/- 3 degrees
Camber: -1 Degree +/- .10 degrees
Toe: +03' +/- 03' Total Toe: +05' +/1 05'

I also have pss10s, somewhere on the forums claim that front camber maxes out at +1.5 with stock control arms. My question is, are front camber plates the only way to increase camber? How many more degrees of adjustment does it allow? Preferably looking around +2.0 front.

FLA996TT,

I'd like to know where you found those specs from. You indicated street alignment, does your source also provide track alignment? Thanks.

You want to be +2.0 positive camber in the front??

Here are the numbers for the 2004 GT3, for both RoW and USA. Front axle height: 115 + 5mm (115 to 120mm) Rear axle height: 128 + 5mm (128 to 133mm) Front axle: Toe unpressed (total): +8' +/- 2' Toe difference at 20° lock: -1°30' +/- 30' Camber: -1° +/- 5' Max camber difference, left/right: 10' Caster: 8° +/- 30' Max caster difference, left/right: 40' Rear axle: Toe per wheel: +13' +/- 2' Max toe difference, left/right: 5' Camber: -1°50' +/- 5' Max camber difference, left/right: 10'

Porsche Factory numbers

keep in mind for the track only. Bet it will eat the tires.

Here are some numbers from I Believe Apex Competition:

Here are numbers for a track/street compromise:
Front axle:
Toe total: +4′
Camber: -1.7º
Caster: 8° +/- 30′
Rear axle:
Toe total: 33’ +/- 2′
Camber: -1.8°


Optimize for track use:
Front axle:Toe total: +5′
Camber: -2.5º
Caster: 8° +/- 30′
Rear axle:Toe total: 32’ +/- 2′
Camber: -2.4°

Mistake, I meant roughly -2.0 in the front and -1.0-1.5 at the rear.

Thanks buddy

Could anyone verify if -1.5 front camber is the max with stock control arms? This is the stance/suspension setup I'm looking to achieve. Any input?

So, anybody know if i can use the stock end links in the rear??

Yes...0 rear toe can be achieved with stock components. I'm on pss10 and have no problem achieving 0 toe

Thats really good to know.. even when lowered an inch?

Yes, I was able to achieve 0 toe even lowered more than an inch. Now, the camber is a whole different ball game.

thats cool thanks.. I have adjustable upper control arms so i should be able to get the chamber set at -1.0 or so.. which i think will be just fine
