I've been reading up on bearings. I found a reputable builder who uses ceramic bearings in wheel bearings. On a 10.0 car he said you can gain around 0.2 off the ET and around 2mph through the traps, not to mention the longevity added. But, he wants 1750.00 to convert plus me providing hubs. Can anyone give me the bearing number off the front/rear wheel bearings? I've found a couple companies that I could buy the bearings off of myself. Or even just a measurement off the bearings.

I've already acquired ceramic bearings for the alternator/tensioner/idler pulley. I know this is probably splitting hairs. But its just an experiment. If anything, I'll gain some longevity if I gain nothing else.


Thanks for any help,
-Michael.

IMHO,,,,,,,, You are spending money on something that is NOT an issue. The USA made hubs are seldom a problem. Yes the high mileage cars can suffer from bearing noise and roughness. Once you change them, you have another 100,000 miles not to worry about them.

Our HUBS contain a WHEEL SPEED SENSOR in each Hub. Any auto parts store will have the GM replacement hubs. See if you can find a hub with TIMKEN Bearings. Those are reliable and seldom fail.

I can send you pictures of a front and rear hub and show you the internals if you PM me an e-mail address.

Give me your thoughts. I thing the COST outweigh the benefits…

If I recall, our bearing hubs DO NOT have ball bearing assemblies. The hub is a machined part that has an outer race as part of the hub and the ***** and center race are a separate part. I can look if necessary.

I don't think your BUILDER has ever tried to convert a C5/C6 hub. I could be wrong. LOL!

 

When it comes to racing every little bit helps.. knocking 0.2 off an ET without adding power to the car or shedding weight is an obvious GOOD idea and a huge gain. Ceramic bearings last longer than OE, I'll probably never wear out the factory wheel bearings, but for accessories/tensioner/idler it will help them live longer, esp since the car has a SC with added belt tension. To swap out everything the serpentine belt touches with ceramic bearings is around 200$ for hybrid ceramic bearings.

Nothing about any of my post was about fixing a problem, it was trying to make a car work better on the track.

He's not MY BUILDER. He's a guy that used these type of bearings in DSM/EVO/GTR's. I went to him with the idea of converting a c5 front/rear hub. So yea, there's a good chance he hasn't dove into a c5 hub assembly.

I need the number off the bearings. I was hoping someone would have one laying around. I'm not even sure if there is a number on the bearing, but I was trying to keep from having to take mine apart or buying one at a parts store to find out.


The cost, at 1750$ hurts, but if it could be done for under 1k$, tell me what other mod would net you < 0.2 of the ET for less than 1k that doesn't involve turning the power up/losing weight?

The car is as it came from factory with added cage, cam/bolt on's/ECS kit. It ran 10.12. The guy I bought the car off of sold it to me due to a terminal illness and needing the money for a motorized wheelchair and van with accessibility. His plans were to run a <9.99 without adding anymore power. So in honor of his wishes, that's now my goal. Adding ceramic wheel bearings are a no brainer if they'll net you <0.2 off the ET.

 

Imageracing5@aol.com is my email

If you can find the numbers on them that's what I really need. If the hub has the outer race made into it, it might not be as easy as I had hoped.

 

PM me an e-mail address and I will send you some pictures and I will look fo a part number on the old units that I have.

 

Woops,,,, you already did!!

 

E-mail sent with the pictures promised

 

Spray it with a nitrous kit for a lot less than $1700 will get you more than .2

 

LOL!
