Install was the same for both, I just bolted in the mc in place of the beetle part. Now I'm using 87 944 turbo disks, and 4 pot calipers all around so I'm not sure how well this setup would work with n/a brakes. The porsche 930 of the same year used the same brakes as the 944 so the mc matches the calipers. The 930 mc with 944 brakes is like hitting a wall if you jump on the brakes. The 930 mc also has dual brake light switches that connect exactly like a beetle mc (the 930 mc I bought even came with new switches).
