I asked this in the '13 thread, but I'm guessing most are here now

Do you guys have a preferred bearing brand? I replaced my bearings with an AVID "Revolution" bearing kit, and although they are butter smooth, there is a lot of play in them which causes more slop. The Xray bearings seem tighter but not too durable. Do you guys go with Fast Eddy, Boca or anything like that to keep the slop at a minimum?

Xray for me. No slop, low friction and the seals seem to do a good job of keeping the dirt away outdoors.

I don't race indoors though so can't comment on durability if you smash them into some 2x4".

I use avid exclusively in my cars for replacements. I don't notice any additional slop from using them and I'm very particular about that stuff.

Which Avid, though, metal or ceramic? And Revolution or... ? I'm wondering if there is a difference. I just got the metal Revolution, so rubber shield on one side.

I just get the metal balls and metal shields on both sides for onroad. I always clean the grease out and then use oil. Frees up the bearings (less drag) by doing that.

For off-road I buy the revolution and just install as is with the grease.

Anyone have a problem with the inside rim of the front wheels rubbing onto the outer camber link ballcup? Using sorex wheels(RevLite) outiside cups are getting grinded by the inside wheel edge. Have the 2mm spacer as the book recommends.
Is this common or did I goof up something?

Since we're talking about rubbing, anyone running VTA wheels and tires? With stock hexes, my inner wheel rim rubs on the bottom of the arms in turns, the car comes off the track with white plastic shavings underneath the arms and a small groove. This was with 2.9 front springs. I tried +1mm hexes and it's better but still a little rubbing. I'd like to try 2.7 front springs but I worry about even more rubbing when the arm moves up.

I had a similar problem with my Foam Tires, both front and rear. I solved the problem by adding a washer in between the hex and the wheel (so similar to running a +1 or +2 hex). I believe I had to add 2 washers to keep it from scrubbing at all. And just to be clear, is it the inner part of the wheel near the spokes that is rubbing? Or is it the very outer part of the rim?

Yep, the inner edge of the wheel, closest to the chassis. If I compress the arm enough, almost fully collapsing the shock, it touches when the wheel is turned. Specifically the leading edge, so front of arm, outer wheel in the turn.

If you can't solve it with a few shims, you could always limit the steering throw. Set it at full suspension compression and then dial out steering.
