| Post subject: | Foam Tire Wear Q |
I'm getting more wear on the outside of my tires than the inside. How can I prevent this? (Note: I'm running -2 deg of camber, is this too much?) Last week they vacuumed the track (Carpet) and I'm having a problem with the rear end stepping out on me midcorner. Any solutions? Thanks -Dan |

It is not unusual to run up to 3.5 deg neg camber on foam[on the rear] so you could add some more camber ,or shorten the rear link length ,or raise the outer ball stud [on hub] both these the will result in more camber change which should help with the wear problem. When the tyre wears in the manner you have mentioned this can result in an unstable rear end. Quite often i cut a taper in to the tyre on the tyre truer of .5 to 1 deg like you see run on the back of 1/8 onroad gas cars this can help also. Just one other thing to note if you are using some of the cheaper pre mounted foam tyres the rims can be of a lower quality and have much more flex this can also upset the handling and wear characteristics. |

I've just looked at my tires. Its only really happening to the fronts.... Front: 30 wt X-Ray Oil 1 hole open 0mm shims Lower MiddleCamber Link Position on Shock Tower Jaco Orange/Purple Tires Lower Arm Pivot mounts are flat (0 deg caster) I have the older, Evo2 bulkheads I'm gonna try the 2mm shim suggestion. Too bad my tires are already coned though |
