No wacky stuff like one ways or anything is good.
One-ways depends. At the TCS race at TWOH I would have given anything to take out the one-way in my 415-that car was so evil to drive (fast-when MR set-it up for me for 2nd qual, but still evil). It would have been slower, but very consistent.
BUT-if you come up with a good diff set-up and a good one-way set-up-the one-ways gonna be faster. Not only will it carry more corner speed-it will rocket out of corners with more steerng and ooomph, but will demand a better control of throttle, which is fun!!
As others have eluded to (and you know I am no expert-but know a bit), the shock pistons and oil dont change too much (50/30), but you drop a good 10lb on the front spring and about 5 on the rear spring. Sometimes you run the shocks further out on the arm as well.
Lower hingepin height (RC) doesnt need to chnage much, but often you will chnage the camber links.
Usually less caster (2,3,4º)
Sway bars are often used, but thinner ones than with foam.
YOu feel things happen in the suspension of a rubber tire car as well and you can control the rate at which things change much better. Everything happens slower. YOu feel or should I say see imbalances in the roll rate of front and back of car.
As for tuning-you dont tune for rubber like foams so thats a fun challenge. as you know on foams your balancing between retarded amounts of steerng with corner speed and driveability. IN rubbers first you need to find grip, then balance, then work to keep the car flat as grip increases.
Having said all this-its sad to say I couldnt set-up a BAD rubber car and make it a whole lot better, YET, but these things I have mentioned are universals for rubber/carpet.
