Hi all, trouble with my car pulling to one side, they put her on the alignment rack and couldn't align, the tech says its because the rear subframe is shifted, seen commonly in tracked cars, (I dont track) and that the solution is to shift the subframe back into position, then the rear will align properly. anyone else have this problem? os this the best solution. I was told the rear subframe does this to protect the car from bending and it makes sense, but Im not an engineer, I don't really care for an aftermarket solution, Im hoping this solves the problem, thoughts?

 

never heard that for gt3's and i have tracked many over the years

 

I thought only the non GT cars had rubber bushings that allowed the rear subframe to wander out of alignment under heavy track/street usage.

 

^^ they said 4 bolts need to be adjusted and its common, dealership works on lotsa GT cars

 

anyone else?

 

I had the same problem it is was very easy process just 4 bolts when you loosen the bolts subframe naturally shifts back to old place. Dont for get to torque the bolts back to recommended spec.

 

do you track often or was this from street driving? have you had to adjust more than once?

 

I noticed it after i bought it, first owner lost control and hit the rear fender into barrier he is my friend by the way so i know the car very well. When i check the service record and repair documents no rear control arm bent or broken but the rear subframe is shifted and service didn’t understand it and deliver the car to him like that he is poser car guy so i don't except him to feel the problem

I noticed the problem while my first drive on highway it felt weird i knew there is something wrong and start digging.

When we lift the car it was obvious, best way to understand is to check the rear wheel steering it sits very close to chassis you can measure the distance between them and cross check the each side.

As i said it’s very easy fix loosen the 4 bolts on the lift and subframe snap backs to ideal place and don’t forget to torque the bolts to recommend specs.

After adjusted i did several hard sessions didn’t have any problem.

 

^^^ so overall do you think its common?

 

it is not common
but it is easy to fix
I am not sure why your tech even brings it up
it's like serving soup noodle without spoon, just bring me the spoon, there should be no conversation ended. you need a real tech
many shops work on GT cars very few knows what they are doing

 

Post your full alignment including all secondary angles - if you can't get a car into alignment its usually been hit or hit something. If you post your full alignment with secondary angles its very easy to diagnose whats wrong. The Porsche techs don't know **** from clay.

 

here it is, she has to go back for the subframe adjust

 

As i understand you have problem in the front right ?

 

slight right pull

 

Had same thing on the front easy fix
