Kerscher rear brake kit

[scourtaud]

Hi,

I just got a set of 16x7 Fuchs wheels for my 1303 convertible and as I presented them on to the car today, I discovered they won't fit under the rear fenders.
As it turns out, my first mistake was fitting a rear disc brake kit for Empi a few years back as it widens the track by about 15mm on each side.

I am now looking at switching to the kerscher rear disc brake kit but I was wondering if someone knew if it widens the track?

Thanks for your help

Sebastien
