I have an appointment with my local Porsche dealer (Reeves) on Monday to try and maximize my alignment for tire wear and grip for DE's and autocross. However this is also my wife and I 3rd car which we drive during the week and weekends around town.

I talked to my dealer and they said they could max out the negative camber "with in the specs for a 997S" to help on tire wear at the outside edge. I have read on this forum something about negative 1.5 degrees for front camber and negative 1.8 degrees for rear camber.

Has anyone done this to there 997S before and what where your alignment specs?

Thanks!!!!!! Mike

 

I doubt you will get anymore than 1 deg front unless you have camber plates or you lower the car

the rear is no problem beyond 2 deg is possible

depedning on your experience you will find that front camber is not enough, cording tires before wearing the inside

i think max the front and add around 0.5 in the rear would be best anymore and you will get too much understeer (increases with relative rear-to-front camber)

2 deg camber is no problem for street IMO

 

+1. also set front toe to +0.02 deg and rear to +0.18 deg. to to improve turn in.

 

Yes at my current level I would rather have under than over steer but I want to wear the tires more even and get the best possible grip too.

 

^ it depends on track and driving style only you can tell what's good for you

from my experience if you put 2.5 deg or so in the rear and max the front you will probably have good wear for the rear but not the front and change fronts twice as much as you do for rears

 

why not get this done at a race shop and let them do a ride height check and a corner balance? delaers are generally quite sloppy with alignment.

 

That is good advice. I will ask around at this weekends autocross and see who in Tampa specializes in Porsceh alignment.

 

With new H & R springs I recently set mine to the max. obtainable and that was neg. 1.5 front and rear with the hope that as the rear springs settled the rear camber would increase to 1.7 or so.....

 

Well you were absolutly correct. For track and street use they set the front camber to the max they could get at -1.03 degrees left front and -.58 right front. This is the best they could get. Toe is now at .03 for both. Rear camber is -1.51 of both and 10 degrees of toe. They worked on this all day and the car drives really straight.

 

front camber should be the same for both sides otherwise car would not handle well at high loads. front toe is good. rear camber is quite low and rear toe does not sound right. did you miss-type the numbers?

 

+1 take to a shop this is not good IMO

 

Here is the shop read out:

AFTER ALIGNMENT...............BEFORE ALIGNMENT
FRONT LEFT............................FRONT LEFT
Camber -.58............................Camber -.47
Caster 7.45............................Caster 7.45
Toe .03.................................Toe .10


FRONT RIGHT.........................FRONT RIGHT
Camber -1.03........................Camber -.39
Caster 7.42............................Caster 7.42
Toe .03.................................Toe .05

REAR LEFT...........................REAR LEFT
Camber -1.51.......................Camber -1.46
Toe .10................................Toe .10

REAR RIGHT........................REAR RIGHT
Camber -1.50.....................Camber 1.32
Toe .10..............................Toe .12

 

they did not do a good job with the front. i would check the front ride height on both sides to mae sure its not limiting you from getting equal max. camber on both sides. if that checks out ok then max the camber on front left side the set the front right side to the same value. i would set the rear camber to -1.8deg. (stock). good luck.

 

also caster should be up to 8 to 8.5 deg. and equal on both sides.

 

Here is the specified range for a 2006 2 wheel drive Carrera S. Everything is with in spec compared to my setting in the post above except for the Camber which I requested to be as negitive as possible for street and track driving.

Thanks in advance for any help with this post!

SPEC RANGE FRONT
Camber -.40 to -.10
Caster 7.40 to 8.40
Toe 0.00 to 0.05

SPEC RANGE REAR
Camber -1.45 to -1.15
Toe .05 to .15
