The correct aluminum version is "wide". Make sure to order the "outer" one also. I broke one this past weekend.

KYOUMW515GM is the "wide" outer/rear
KYOUMW514GM is the "wide" inner/front

"GM: is the gun metal version

You could try the bike chain lube too.
hhmm... my mind is now moving.

andy.. good idea. But just so you know, my receiver mounted/servo taped up perfectly on the side pod with 0 modifications. I just used a little 2 or 3mm strip on the bottom, and a 2 or 3mm strip on the SIDE of the receiver, and it is mounted as strong as any receiver I have ever mounted to a flat chassis. You can see the side servo tape in this crappy picture here.

Car looks 'ok'... but would still be considerably better in RM on that track.

Was that the leading car? Seems like it needs a bit of drag brake, she was nose up on almost all jumps as well...
