Anyone done it? I am trying and there isn't enough clearance with the knuckle and it rubs on the lower UJ clevis when cornering. I can grind the corner off but its only gonna give a few mm extra. The engine mounts are in good nick recently done.

What are some options?

Spacer under the engine mount,
crush the tube a bit
grind a few mm off clevis?
?

I *think* the angles of the pinion are slightly different..

BTB3 and Z3 rack works - I had both on my M20 - no issues at all - well, apart from the ridiculous prices... :thumb:

did you use standard engine mounts? how much clearance did you have?
