This is a very difficult question!! I talked to SKF in Sweden, and they told me that my bearing 3205 A-2RS1TN9 was more shielded from dirt than your SKF 5205 A 2Z Bryan.. BUT my bearings is not capable of more rpm than 8500.. when the car does 8000 rpm, will the bearing have higher rpm since it is smaller wheel?

Your bearing SKF 5205 A 2Z is capable of 12 000 rpm, but not as shielded as mine, after what skf told me.. The guy I spoke with at skf would not reccomend any of the bearings before we knew what rpm the bearing have..

I'm all confused about this.. I have given the guy at skf the link to this tread and hopes he reads it, and let me know what he thinks. He was a nice really nice guy..

Do you have any news Bryan?
