Standard Gearing on NSR GT Cars with Sidewinders?

[Fast Co.]

What is the standard gearing on NSR GT cars with a sidewinder set-up? All of my GT cars are angle winders.

This is for the C7R

Courtney: the gearing you mentioned is for the anglewinder car: Steve was asking about the sidewinder.

Steve: I just checked my Mercedes with the sidewinder pod and the 25K Shark motor: looks like 11:32

Thanks guys!

What do you think the issue is that it didn't perform as well as expected?

Possibly the Shark 25 motor is too powerful for that car when you are running without traction magnets. If it was me I would try a lower (numerically) gear ratio, maybe 12 or 13:32. These cars are also very fussy about subtle differences in things like body float, pod float and ride height. A half turn of a screw can make a big difference. Tires are very important, it is best if they are glued and trued. Rubber tires often have batch to batch differences that affect performance, that is not a problem with silicone or urethane tires. It is nice to know if the tires that you are using are a problem. If you have a car that runs well it would be safe to assume that the tires are good. As a test you could swap those tires to another car with handling problems, if the handling improves you would want to work on the tires before you tried anything else.

Sir Slab thank you for the update. It's Friday so I know there's more you will gain out of the Merc prior to November. I'm sure it will be your usual top 10 performer.
