They no longer make those ones. Those used the old rdx uprights and cut off where the horizontal ball stud would mount and tapped holes for a vertical one. Corally stopped making the original rdx uprights and specialized no longer had access to making the vertical ballstud upright you posted a pic of.

I am sure that someone on this thread would probably have a 2.9mm foam chassis that they want to get rid of.

What belts do I need to run 36t pulleys with the standard wheelbase? I have the stock rear and the tamiya right now with the cam back the tamiya is too short, and stock too long.

What is the difference between the stock rear uprights and the new vertical ones? Do they make the car handle better or are they just stronger?

Im running a 4mm, and have a 2.9 back up if anyone needs it. if not, i plan to hang on to it.

Kobiwan,

They are completely different, its not only the mounting system thats different but also the cvd is placed 1mm lower! so that creates more steering and more rear traction!

Maybe you you REAAAAD no short wheelbase, just both 36t pulleys to get the lower ratio, but yeah if it's going to cost $75 in parts that isn't happening right now, lol. There is no belt that fits the stock cams?

OllieRDX

i drive the 36t pulleys with 20t center pullyes
standard 507mm front belt and serpent rear belt! but short wheelbase and the optional diffholders!

It seems I can get away with the 42s and gear it where it needs to be, I can see now that the optional holders are required unless you find a longer front belt and a belt inbetween the short/long rear belt.

OllieRDX,

So, if I throw the new vertical rear uprights on my car, am I going to notice the change in handling? I'm just trying to figure out if they are worth spending the money on.

at my local track, on low traction we run the old cut specialized ones and they help alot with rear traction and getting angle into the camber links, going out of town to high traction we have been putting the normal hubs back on. definetly a plus for low traction, i run xray camber link thingys where you put the screw through the middle of them rather than running a ball stud with the cut hubs, you can get the link lower and its easier to shim for me.

If you are running mid hole on stock upright then run inner most hole and 2 corally steel washers feel will be very close to the same. If anything better being alittle more stable.
