Sorry to hijack, I’ve just picked up a hardtop for my Z4 (looks identical to V8rumbler’s, silver grey with red leather 3.0Si and a sapphire black hardtop!)
We fitted the top last night, but driving back to Dorset, I had a fair amount of wind noise on the drivers side, also, the end of the side window rubber doesn’t meet up with the top of the a pillar rubber so you are left with a 10mm gap, it looks like that side of the hardtop needs to move forward.
Can you adjust the mounting point behind the drivers door??
And if so are there any destructions for doing so?
