I've recently lowered my b5.5wagon about 60mm on AP coilovers. Since fitting I have tried to get 4wheel alignment done, older systems at my local tyre place won't fit because it's too low. Another place which has a hunter equivalent couldn't fit his system on there either. Mt local volvo garage has a hunter system but when i phoned them he was asking about factory settings, so I explained to him again that it was lowered on coilovers, when he started going on about factory settings again. I thought "I'm not sure this bloke has a clue what he's on about"
so basically I'm none the wiser.
can anyone with a lowered b5.5 wagon help me...how have you had your wheel alignment done, what system you used and what settings you worked to. Any help greatly appreciated.
