ceramic bearings
 
Do ceramic bearings actually help performance, or no? This topic came up the other day. Your comments please.

Im getting them for my front wheel bearings and rear end bearings. I'm looking to see MPH not ET gains. But no, I have no actual experience with these.

The 200 mph plus bikes at Bonneville all use them. I cant speak for the cars but they must work, but they arent cheap.

Anything and everything you can do to reduce drag is worth et. I had the first all roller bearing 4 speed in SS and it was worth et. I probably had the first ball bearing carrier in comp and my car would roll in the staging lanes when others would not. I had unknown "helpers" who would comment on how easy my car was to push. (In A/SM at 3,000 lbs.)

I have a friend who works on an IRL team. (One of the top qualifiers) They (IRL) only allow ceramic bearings on the right rear because of the cost. Otherwise the well funded teams would have them on all four corners. Cost.... $17,000 for the RR. If you wanna be fast, no stone goes unturned. You do it all. Does that answer your question???

Yes. Thanks, but I believe I'll pass at this time. A little too spendy if they cost that much.

They don't cost $17,000 for a passenger car. Indy or F1 cars are another breed of car!
Call Jack & get a quote.

Not really. Just a different design. The same technology that applies to those cars applies to these cars as well. Take your pick.... carbon fiber, titanium, ceramics, aerodynamics, lubricants, fluid dynamics, and on and on. Just like carbon fiber brakes. I don't know what they cost now but I bought them when they were $3,300.00. Money well spent. I had a titanium bell housing in SS back in 1989 before they were ruled out.

Ceramic bearings are relatively old technology. Back in the '80's a friend of mine worked at shop that build small turbine power plants for the US Military similar to the ones used in cruise missiles. He put me onto them back then. If you want the latest and greatest, the lightest and fastest, start looking at F1, IRL, NASCAR, Military and Space technology. By the time most of the Sportsman racers find out about it, it's old news.

Rear axle bearings from Performance Bearings are just over $210 each. Pinion assemblies range from $877 to just under $1K. Carrier bearings around $600 for the set. I got a quote for doing angular contact bearings for the front hubs (Mustang II stuff) at $550 per set.

For the class I'm building this car for I'm thinking it is well worth the cost.

used to inline speedskate in the early 90's and one kid got them and they made a lot of noise but dam he would just roll away from everyone. then they sold them to everyone they owned a shop
