Replacement springs and dampers 964 - issue

Hi,
Wonder if anyone can through some light on what I am being told by a Porsche garage.
I have recently fitted Eibach spring and Bilstein Sport dampers supplied from a well respected source. The springs lower the car by 30mm. As a result I was aware that ride height , toe, camber and caster would need adjusting.

The garage stated "all 4 dampers heights set the same on the bench. When fitted to the car the heights are all miles out and uneven. Removal of wheels 7 times is required to correct ride height to equal settings. Now 4 wheel alignemnt and suspension setup is carried out. The spring plate lower support heights are all set to different settings which indicate possible different spring pressure. It may transpire that the vehicle will settle and further setup may be required".

Could they have mixed front and rear springs up. I assume there would be a difference between front and rear - am I correct or wrong?

This I find most odd and I wonder if such a response is reasonable or correct? Any thoughts greatly appreciated ASAP.

many thanks
James
 
Removal of wheels 7 times? All sounds very confusing. I'd recommend you take it to a respected Porsche indy for a geometry set up. Where in the UK are you?
 
Yes, set them on the bench, put them on car, and all different - of course. Car is not same weight at each corner. So when properly setup the spring platfroms will be in different positions to account for this. I guess ideally you would have all your suspension alignement done, camber, caster, tracking - then get the car corner weighted and set the ride hieght. Not sure how many people both for road cars though. Either way, advice above for decent indy sounds about right.

The only bit that worries me is the above, surely the garage could have predicted this.

I agree ..... thats why you have the adjustment! Not sure why they are taking the wheels off to do the adjustment either. Ride height is set with the wheels on the car, so that all four corners are taking the weight!! Taking the wheels off, i would be surprised if they would ever get it right ;(

Not sure where in South Wales you are James, but i would certainly consider and highly recommend a trip to Chris Franklin at Centergravity.[;)]
