Neither of the bearings you reference will work. You need this one:

Good luck

Thanks for the help fellas!

Posted this in the DB12 thread already, but figured I could get an answer here too.

Thinking about upgrading ESCs. If I do, I'm going to get an LRP SXX. Do you guys run these by any chance? I currently have the Speed Passion Stock Club, and trying to fit everything in is proving to be quite difficult. If I get a Stock Spec SXX, I don't believe I'll have to run a Rx pack or a regulator, which would be nice since everything is jam-packed in the vehicle now. The SXXs have a pretty low profile, so I think that it would fit fine, but I'm not positive.

My friend has an SXX Stock Spec V2 in his 12R5 and it fits quite well. You don't need a booster or RX pack. Seems like a really good ESC, wish I had one.

You can run flanged bearings in all three positions in the 12r5/5.1 diffs. Just make sure they are the 1/4" by 3/8" size; the same as what is in the rear pod holding the axle.

I needed to use an unflanged bearing in the spur with the CRC spur gear on my 12R5. The flanged bearing pushed the gear to far over for the balls to contact the rings.

Right, the CRC gear requires a flange less bearing because of the 3/32 balls.

Ran a few practice packs thru the 12r5.1 with some of the changes today. Running Magenta fr, Pink rr and 6.5' caster with a Parma Speed8 body and found the car stable at speed but loose in low speed tighter corners. Is there a body that may help me, or car setup? Or is it as simple as drive more to me confident corner faster.

Post your full setup
How are you saucing, what sauce ?
Springs
Droop, frt, Rr
RH
etc

Is it loose on corner entry, mid, or exit ?
Some times Yellow has a lot more rear grip than Pink on pavement.

Good point. I had only ever ran the 76 kimbrough with three flanged bearings.

I tried 'Jack the gripper' for 20min no warmer on the rear, but I must apply to much and/or not wipe it off well enough as it was super slippery until worn away.

Tyres fr Magenta, rr Pink. Diameter from packet.
Springs fr .020, side Blue, center Gold.
Shock center 30wt, side damper 20wt.
Ride height 6mm fr/rr with 0.5mm pod droop and 3 shims on kingpin as per kit.
Camber -0.5, Caster -6.15.
Parma Speed8.
Bumpy low traction asphalt with both open and tight corners.

Any info I've missed is as per kit.

Blue side springs are a little stiff, most guys I know running 12R5s use silvers or even greens. Try longer and shorter on the Jack and see if it makes a difference. You do need to wipe it really well, but any slipperiness should only last a lap or 2.

I'm assuming that the rear end is looser than the front. Other things you should try are a softer center shock spring and more pod droop. Both changes will help rear end traction on power.

Xray XII Link vs 12R5.1. Which and why? I don't mention the CRC because I've heard the plastics bend easily and it affects handling.

I used to run the CRC front end on my BMI..never had any issues with the plastics bending. If anything it was stronger than the old AE front end.
