I take it with the inner position, you get more camber when the suspension compresses in comparison to the outer position?

Why is the 3mm shim necessary?

Cheers, Mark.
The kit is 2mm. The higher it is the lower the roll centre so more camber change. Even with no roll bar my tyres are coned in on both sides after 5 min heat.

Check with Boca Bearings. They make a few different types of ceramics. They are very nice but expensive.

Ah, ok I understand. But you wouldn't always want to change the roll-centre, so maybe it is better to try just the inner position first?

Jeffrey: How many hours do you think you're getting between bearing changes and are you changing all 23 bearings? Which ones don't you change?

I did some simple math and total on-track time for me will probably be no more than 24 hours all year - one hour per race day (practice 30min, 2 qualifers @ 4min each and 3 mains @ 5min each) x 24 races a year.

It's hard to say. As I mentioned earlier, the bearings go bad mainly due to collisions and dirt. So depends on how the race go, I may replace bearings as often as one race if I had a bad hit. On the flip side of that, some bearings are still good since when I built the car back in 04.

The wheel bearings especially outside ones tends to go bad easily. Bearings in the drive-train usually last a long time.

Please note that I have very strict standards when it comes to bearings. A lot of bearings I replaced might be consider good by others. I will replace them if they feel the slightest grittiness and not complete smooth.

Mark I hate to disagree with you on this point......But the ceramics make the rrr drivetrain significantly smoother, it makes the car free in all aspects....Another point most of the top guys right now in the industry are using ceramics from one manufactuer or another.
there are some certain keys that help you get the most out of the bearings other than just putting ceramics in Im personally using Boca ceramics and it was a huge difference when I slpapped them on.....and they last.

Cheers friend

Remeber there are many things you can do to free up the drivetrain....ask and you shall receive...

I have been racing Consistently in S.Florida for about two years every weekend......Racing all over the place.....I have noticed if you constantly maintain you bearing periodically you rarely have to replace them.....it takes alot of work but it save you having to replace bearings...its not easy but trust me it works

Rob,

What bearings are you using? Would you happen to have the part numbers handy? There is so much to choose from, I want to make sure that I get the right ones for the RRR WC Edition.

Thanks!

Default bearings

I agree with you Robert, at least once a month the car comes completely apart and so do all the bearings. Cleaned and regreased and maybe if its for the main in a national they just get some after run oil
