the bronze pivot balls are worthwhile in the upper arm since they don't ever seem to develop any slop. But the neither the bronze balls or the hardcoated aluminum ones work nearly as well in the lower arm as do the standard issue nylon balls. On the bench, when first installed, one can be fooled into thinking that a new bronze lower ball is an upgrade since it yields slightly less play than most nylon balls. But if you push up on the out end of the axle (which is the force that is actually imparted on the car when it is on the track), the sliding action of the kingpin is notchy compared to how it will side thru a nylon ball while the axle is under load. Even if you can get the new bronze ball to slide smoothly when first installed, as soon as you run the car once and check it again (by pushing up on the outer end of the axle), all of the metal balls will soon develop a notchyness that doesn't occur with a nylon ball. Your money is better spent on the occasional replacement of the lower balls with new nylon ones. Bronze is great for the top, but it sucks for the bottom (where it is critical to have reliably smooth sliding of the kingpin).

The situation that you describe with the lower ball sticking is precisely thae issue I was having with the plastic ball. Replaced the ball, same issue. Replaced the arm and ball, same issue.

I'll give it a few runs and look out for what you're describing, though. Thanks for the heads up.

Ive recently purchased a 12r5.1. I took it to the track yesterday for the first time, and bounced it off the boards, i was very suprised not to break the car with any of the hard hits, i did managed to smash the centre out of a rear CRC whee,l destroy the body and rip the speedy off the chassis tho.
*Its my first onroad car*

How much throw (in Deg) should i have the steering setup with?
also how much toe do you guys run?

What's the advantage of having the battery in line and to the right with the electronics to the left?

I have a Futaba S9650 servo, but I have an Airtronic M11x radio. Do I need to mess with the polarity at all? Also, can I just dremel the little thing on the side so it will fit into the receiver?

NO, polarity should be fine.

If your nylon balls are not rotating smoothly, it will affect the suspension movement. You can take them out (using a ball popper like the CRC one), mount them in a drill or dremel (use a long countersunk 3mm screw and a nut to make sure the ball mounts centered), and take a little material off. I used a scotch brite pad with a bit of cream metal polish for lube to prevent dry scratching and keep the ball smooth. Careful, though... you only need to take off a hair, otherwise you'll end up with slop. Spray it off, remount, and it's glass smooth with no slop if you got it right.

Must be something to do with better weight distribution or something

I think more balance in the car, and more cornerspeed....

But it would be nice if someone fra AE could answer what is going on....

Many other cars to chose from insted of buying a car that is going to be discontinued..

Just testing to see if something might be better for the future. Nothing new at this point.
