The official alignment spec and review thread

[Brad Roberts]

and no one has come back in to state what worked and what needed to be changed

um.. you know why? kickass alignments are done to YOUR DRIVING style not somebody else.

You are asking the impossible. I have hundreds and hundreds of setup notes.. each driver may like something different. It comes down to what YOU like.. not what somebody "told you"

also.. stock? really? you are limited to about 90% of what was posted above!!

Are you new to this? Do you have 20+ years of driving experience? There is NO magic setup that will compensate for a slow driver!!

Ready? start here:

max negative on the front, then match the side that comes in with the least amount

run 2mm total toe out in the front and 2mm total toe in on the rear

on the rear, run .5 less camber in the rear than you manage to get out of the front.

example: end up with -.5 in the front, run 0.00 in the rear, end up with -1.0 in the front? run -.5 in the rear

Is that a lot of toe? yes, but you are probably on worn ass out 100k mile rubber suspension bushings that flex all over the place under braking and turn in... which requires us to run more static toe than normal (for autoX)

You know from all 1million + posts that running autoX on stock suspension does nothing but eat the sh_t out of front tires do to lack of negative camber achieved by the front struts...

Good luck..

Thanks. I have 28,700 miles on the car, but yes, it is sitting on 14+ year old bushings. I will be headed into the alignment shop in a couple of weeks and have taken notes. Thanks again.

I was looking for a good starting point since the OEM set up (the one presently on the car I believe) doesn't have the turn in that I am use to.

Yes stock. I have run SM2/SSM/EM in a SCed S2000 for years and switched over to a CR-Z in HS last year. I have a new (to me) Boxster and would like to run in CS this year to see where I stand against the M3's that have been winning that class for years here.

Yes I do, 30 actually and 10 autoXing. With the S2000, people found that the UK alignment specs made a HUGE difference in the way the car responded. I was hoping that there was a setting for the Boxster that would do the same.

[Brad Roberts]

oh.. thank you

Then you do know what you are doing

Ping me offline.. I'll tell you how to take 90% of the slop out of the stock suspension and not replace a single part and still be legal for SCCA stock classes.

Hi Brad,

My 2002 S (58K) is going in for an alignment this week and I would really appreciate your insight regarding the comment quoted below!

I don't think Brad's been around for a while now. I've been wondering about that same issue for about the last week! Short of pressing out the metal locating inserts and having sleeves machined, I can't think of anything. Does anyone know if the rubber is solid from one side to the other???
