Iv used acl bearings on loads of big power ybs including my own..i like the way you can order them in many different sizes after plaster gauging them..
Also used cometic hg s on many big power engines with no probs although about 5 years ago there was a few that went wrong...
But now with the price of the wrc hg not being so bad theres no point i n using anything else..5 years or so back a cometic was like £100 and wrc £275 so a lot of difference but now wrc is only £125 so why use a cometic at £90???
