4 or 2 rear idlers

I have a rx-1 mc express turbo running 300+ hp 162 track. My question is, running two 8" wheels in the back going to cause problems?

Been lot's of discussions on this. Lots of stress on just 2 wheels, especially standing on it's tail, although some get away with it. Personally, I run 3. Some guys run 4.

I run 4 this year, i agree with Slymax, lots of stress made me go from 3 to 4.
I heard about clearence problem running 8" with 2 1/2" track!

I prefer 3 or 4 wheels (better 4 wheels) for higher hp sleds.

On my turbo RX-1 I have run 4 wheels both in the Proaction and the current ZX-2 skid, when running studs it's a must in a high powered sled helps avoiding derailing the track.
