I have one shim on each side at the moment, but think this is probably just a touch too much. It isn't tight, but there is virtually no float. Think i am going to get some thinner shims so i can effectively take less than 1 std shim out.

Is there any disadvantage of "float" or "left-right slop" in a belt driven car's tranny?

It's all good. I'll be out there for the race on the 28th and go from there.

I don't remember exactly, but he measures top of the axle to the pit board and it was in the 23.5mm range. I would probably start around 2 or 3mm above ride height

I only ended up with one shim on the front diff and none on the rear and it seems fine on my EC. The drive train is super free on my car for just being built. I get to run the car tomorrow for the first time then at the Novak Race later in the week. The car looks really good so far I will be able to tell you guys more tomorrow night.

Teemu measures his droop from the pit board to the top of the axle. I don't really like doing it that way. I measure the droop as above ride height. Set the cars ride height where you want it. Then lift the car by the center of the shock tower with the shaft of a hex wrench just until the tires come off the ground. Then use your ride height gauge and measure your ride height again. The difference is your droop. If you set the car to 5mm ride height and lift it up until the tires are just touching and measure again and you get 8mm, you have 3mm of droop. Then use the actual droop gauge to make sure both sides are even. I usually run between 3 and 5mm of droop above ride height.

I personally find Teemu's way very accurate.

What you can do is make up a spreadsheet that lists combinations of tyre diam, desired ride height, and desired droop (above ride height)- and then gives you an axle height measurement.

The formula is: tyre diameter/2+2-rideheight-droop= axle height (to top of axle).

Measuring below the wishbone gives you pretty much exactly (maybe +/- 0.1mm) 20mm smaller result, so 3mm under == 23mm to axle. Hope this makes it a little easier to compare between setup-sheets.
