alloy rear hubs yz2

[redtyson]

Any body fit and run the alloy rear hubs.
am thay any good what are the gains

The aluminium parts are tougher and stiffer than the plastic parts. They'll generate less traction, but are harder to break. Basically they are more of a tuning option than just for making your car bulletproof.

Ran both on car can't tell the difference handling wise

I also couldn't tell difference. Nor could my lap times

I don't see how a 0 degree alloy replacement hub will generate less traction? I felt no change when I upgraded, but its just more durable and the ball stud won't get ripped out of the plastic. Optional 0.5 and 1 degree hubs will give more rear toe, which will generate more rear traction or less if used in reverse to remove toe.
So durability, bling factor, and adjustment.

mes is right. In theory you get less grip: stiffer material. But while driving you probably wouldn't notice any difference. More flex (the original hubs are plastic remember?) results in more grip, in most cases. So, replacing them with Alu actually makes the hub stiffer, which results in lower grip. Common sense. But, like I wrote earlier, the average driver (like 99% of the drivers) doesn't notice the difference.

Right, there are many things we average Joes will not notice. If you are only running on astro or carpet, the aluminium parts are a no-brainer except for the price. If I ever break a hub, I'll switch to the aluminium hubs for sure, but so far I am happy with the stock items. I'd like to try the graphite suspension parts to see if the car will land even better as they will also be stiffer and leave the bouncy work completely to the springs.
By the way, the way a car feels on the track can be very deceiving. One day I was running my B5M on the Duisburg dirt track with saddle packs, and it felt much better than with a shorty battery. However, laps were two to three seconds slower. Always check your lap times when testing new items! ;)

On the BMAX4, alloy hubs also give you the added tuning option of the angle of your camber links.

I use alloy hubs on my YZ2 when I require 4 degrees toe in, however if I am running 3.5 or under I go back to the stock parts as I like the stock hubs. I've stripped the threads on one since I got the car when it came out.

The only downside to alloy hubs is they have a habit of wearing quickly and having more play than the plastic parts.
