That would worry me..... and you trust them to service it???!!!
BTW, I dropped my Mk2 172 35F/40R using AVO Chassis Dynamic springs, the work was first done by GT Tuning (NEVER EVER TRUST THAT THEIVING TW*T) a couple of months later (when the shocks died) I sourced a set of Koni adj. and gave the lot to my local dealer who kindly fitted them, sorted the geometry and warrantied the lot!!! no issues....
I think the moral of the story is... be honest with your dealer then theres no margin for arguments! and in case any of you are wondering, I stand nothing to gain from repeatedly suggesting dealers, my Mk2 is even an import!!! The smart dealers out there know theres money to be made from us all.... and if they dont take the work, somone else will........
Just my 2 pence worth
Ohh, and dont be afriad of bartering the price with your dealer.... and think about this.... as a mechanic would you rather swap an aircon unit on an espace OR fit uprated parts to an already excellent hot hatch???
