I too bought the ones with the extra clearance...mainly what I was looking for to help with the wear problem. The other benefit I was looking for was the different metal layer composition so I can pick up the different metals in future oil analysis just from peace of mind.

Once I change mine, Iíll post back up on how they fit ( will plastigage them just to be sure they were sized consistently ) as well.
Have you changed your rod bearings?? How did they fit?

Thanks

Whilst acl bearings may be unknown to the m5 community they are a very well known bearing manufacturer in other communities. They manufacture their bearings in Australia and are a 40+ year old company that only make bearings. I’ve used them in a number of Nissan rb26 builds as have so many people in a range of cars. As long as you select the appropriate clearance for your engine they should be totally fine.
