I went out to the Tamiya USA track for some practice yesterday. I put Hupo's Reedy Race setup on my car and it was dialed. Easy to drive but with plenty of steering and grip, definately worth a shot for anyone on a fairly large medium grip asphalt track.

The only difference from the setup is I threw on a set of the Much More premounted 36 tires. And since the setup doesn't list a body I used a Mazda 6.

So, is this configuration unheard of? I never really quite understood the point of a center one-way to begin with, but figured I'd pick one up to see how it felt with a diff. I was surprised it felt any different than a regular one-way (when combined with a spool) to be honest, but it definitely did.
Adam, i heard of this config b4 but yet to try it, from what i heard its a much stable oneway.

How do you guys measure droop? Im thinking of trying the different setup in Ed's site as well. In Hupo's set up, his running #6mm front and #5mm rear droop. Just want to make sure Im measuring the same as per setup sheet. Everything else I can follow except this. Thanks in advance.

Picking a spot under the arm is crutial. making it easy to read and fit the guage under whatever happens to be sticking from under the car . Typically I believe the simplest way to measure it is under the outer hinge pin an front of the lower control arm. Some ppl do it by lifting the car and looking at the amount you life before the tires.. (sorry, tyres) w come off the surface. Thats most likely good for foam but not I think accurate enough for rubber. I set mine as previously stated and 6/4 f/r is what i like on the carpet.. so far .

Thats the bit that is confusing. I hope the setup sheet includes which spot the droop was measured.

Usually under the outer hinge pin, at the bottom of the A-arm.

Corey Whiteman,

Mind sharing your setup from the GrandSlam race?

So is the pic below correct if the set up sheet says 5mm rear droop.

yup, spot on Most setups quote ir like you say, with 5mm and 4mm... whats slightly confusing is that a smaller number actually equates to more droop...

The most accurate way of measuring droop is actually to remove the wheels and tyres, then place the car on a flat plate and measure up to the axles. This way you can keep it consistent from tyre to tyre (they all have slightly different diameters)... and is good for Foam.

David Junn explains the method in more detail here http://www.thard.co.uk/415/tips/DavidJundroopmethod.doc

I found measuring droop at the axels difficult . But if all you have is a caliper with a depth guage I suppose that works. But more ideal would be with the droop guage and support blocks. and w/o sway bars ...
