what suspension components are you running(GT2/GT3 lower control arms, adjustable dogbones, etc)? Not even sure the suspension has this kind of camber adjustability...post a pic of the wheel on car?

something isn't adding up here...must be a severely distraught bushing/balljoint, likely in an upper arm(s), that is deflecting Heavily under load...

Car looks great! Unfortunately no way to do it at home. there are techniques but takes lots of experience to "string the car" Still need some equipment anyhow. Hopefully the guys who did it will re-do?

0 toe in the rear is way wrong. When you accelerate the tires toe out and just shredd!

severe under-inflation along with heavy toe-out MIGHT be possible as well

get some adjustable toe arms and adjustable dogbones for the top. maybe some solids for the lower control arm too

^+1, just go full monoball/new links, and metal thrust bushings and problem should go away...

and if you want to align the car at home, it is possible, without use of strings/lasers/etc...
I do all my alignments at home and have doubled-checked them against laser,etc. bang -on everytime

my goal with this was to get it fixed and not have to throw a wad of money at it. Since its all stock, it should be able to just be adjusted out. If something is worn out that bad, how could it be so similar to the other side? There is only 75k on the car.

definitely worth adding some toe to see if that helps, I still think something is worn out as the pic of the tire shows it eating the sidewall down, not just a bit of excessive inner tread wear....either way you need to locate the rear toe-link and be able to turn the eccentric, the 'large' part of the lobe needs to be turned towards the centre point of the car...to measure you need to make up a quick tool to get datapoints from front and rear rim lips..

i called my buddy and he is going to get it on the rack this sat. What spec should I align it to?

I will rip the wheels off tonight and see if I can find anything worn out. Is this any sort of common problem?

here are the go-to Porsche Motorsport/ Kussmaul settings, maybe knock a degree of camber off the front and rear settings if only street use

Front Camber - 2.5 degrees
Front toe 2 mins per side
Caster 8 degrees -0+.5

Rear Camber -2.4 degrees
Rear Toe 14 mins per side -0+2. 28-32 mins total

Loaded ride height 112mm front, 130 mm rear


As far as worn components it could be anything, will have to check each one for bushing degradation and the balljoint ends for play
