MGA Clutch release bearing

Anyone used the roller-type clutch release bearing to replace carbon? seemed like a goo idea but John Twist says they won't work in an MG because the bearing doesn't ride concentric with the transmission shaft.

That's been a lively debate for a while. I use the carbon; no problems here.

I used one a long time ago and wasn't happy with it. The stock carbon bearing will last 60 thousand miles and more if the clutch isn't ( ridden) at an idle.

Thanks, I guess you should dance with who brung you.

I've used both and am currently using the roller type clutch release bearing on my fairly close to stock MGA race car. I have the MGB pressure plate modification with the MGB front plate on the transmission, so I'm using the larger MGB sized throw out bearing.

When everything is really, really hot after a race, I can sometimes hear the bearing rollers rolling when in neutral. But a standard graphite throw out bearing may drag just the same under similar heat conditions. I think it's six of one, half a dozen of the other. I pull the engine fairly often and usually see one or two moderate chips out of the graphite but can't really see damage on the roller type throw out.

I think you are safe with either, so go with the cheapest and don't ride the clutch.
