Aww, shame you aren’t a little closer. I’m just off junction 31 of the M1 and have lowered a few z4’s now. I recon I’d have it done in less then an hour and a half. You’d have been welcome to come over and id have done it for a few beer tokens.
Pretty easy job, I did it twice on my own car and then I fitted one for a guy who bought the driver side regulator when I was breaking the car for parts last year. Takes around 30 minutes to swap
Hi, it’s a simple fix, under the door there is a black plastic cap. Pop it off and there is a 13mm nut. Loosen it and you can alter the angle of the glass to close the gap. Cheer Simon
