ceramic coated bearings???

[asd_gst]

I was wondering if anyone has used the alc race bearings with the ceramic coating.
here is a link ACL Race Series Rod Bearings (DSM / Evo) - Modern Automotive Performance
and would you recommend them?

Yea those are the usual ones that are used in our engines alot of builders prefer the tri metal because they are supposedly less prone to spinning a bearing.

im confused? the ceramic coating is a added option

I had the same question and the answers I got make sense. Yes it's good to have it retain a thin film of oil on it but unless you have long periods of time between starts it's not worth it. They also pointed out the extra thickness of the coating may interfere with the extremely tight clearances of the bearings to the crank which would be very very bad to make contact with.
I hope this answers your question.

It helps with oil cooling and is suppose to help with crank spin... but... for the added headache with crank/bearing clearance, it dont think its worth it...

I got my pistons/rods/crank ceramic coated but not the bearings since the clearance would have become an issue..

The thickness of the coating is hardly anything. If you really need that extra .0005" or so you can sand the bearing down with 1000 grit sand paper. Better to have too little clearance that you can sand down that too much clearance forcing you to buy another set of bearings. That coating will save your journals if you ever lose oil pressure. Only thing worth coating in my opinion. Coating on the main bearings is more important than the rod bearing but it couldn't hurt.

I just looked at the link and it even says that the coating adds no clearance change.
