Fellow track drivers:
Need some ideas on general suspension components for a V8 track car that you have had good success with. Anyone running a V8 car on road courses that can give me some general set-up ideas would be great. Thanks, Mark |

poly crapite. only cheap alternative. I prefer poly bronze but most owners dont pop for that. Delrin might be better but more exp$
is that bushing out of he shit box? plastic will flow. the shit box has got some serious grip. ...pivot shaft does not bear the weight of the car |

Not the full weight of that axle, but a pivot shaft is under constant load when the car is on the ground (less when raised, but still under load). You'll note that the deformation is only to one side of the bushing. The bushings on each side of the car were deformed in the same direction. |

Man, that deformation would seem to relate to camber loss (or gain?). I wonder how much? |

Man, that deformation would seem to relate to camber loss (or gain?). I wonder how much? Not much. .03 is about a half mm so maybe a quarter of a degree. IIRC, both the inner & outer bushings were deformed but the inner were the worst.....the one in the pic was most obvious for picture purposes so ya got that. The main point is that this was with only 18 months of usage and I would expect it to kept getting worse.....the more OR they got, the more they would bang around & accelerate the deformation. That said, there was probably less movement than with a brand new rubber bushing......but I wanted no movement...or more realistically, as little as possible. |

We are getting zero movement with the needle bearings installed in my trailing arms; however it was a ton of work to get them installed properly (no slop) and properly sealed. Had to fabricate or re-do just about everything. |
