Default Does anyonr have the same prob. with there HPI!!!!!!!!!

I have an HPI RS4-2 nitro. Awhile ago in a race my car started to spin out in right turns only. So I got the setup sheet from hpi and did exactly what it said down to the rollcenter plate kit. Did not cure it. Checked the frame after a month of running and adjusting shock spacers. Found it to be a little tweeked, bought another one, new foams (which I used on a freinds hpi that I set up for him the same way and the car sticks like glue) and now the car spins out in both directions. I am at my wits end here, I tried taking the rollplates out, using just one roll plate,shock spacers(every size you can think of), adjusting the rear wheels, adjustin front wheels, and still the car will do a 180 as soon as i come off the gas a little. The track is a parking lot with some bumps but, the car is spinning on EVERY turn. PLEASE IF YOU ARE A GOD YOU WILL PUT ME OUT OF MY MISERY! I would apperciate if anyone could answer this.

Default Spinning HPI

It's hard to diagnose your problem without car in hand.

Mystery spins can be caused by the engine mounting screws coming loose and dragging on the ground (very common HPI problem)
A bad bearing somewhere in the rear half of the car.
When is the last time that the bearings have had maintenance/inspections?
The dogbones wearing grooves into the diff outdrives can cause spinning.
Look for these things. If not. Try to supply us with some more information.

Default One more thing

Another thing it could be is your rear Camber setting. Anything more than -1 deg will usually cause the car to spin mid corner.
Look in the "Tires for parking lot racing" thread for tire and set-up advise.
