After a spirited run around and over the cones I noticed a rubber smell persisting. This week driving to work I heard a squeal. Today it seems the right rear tire is rubbing the inner fender where the box projects towards the wheel. The camber has become more pronounced and is visibly tipped in at the top of the wheel. Tires are 205s, but they cleared before. Clearly something has changed, and I suspect that in fact it changed during the autocross. Can you help me with ideas? The suspension console looks ok but the car has rust separating much of the firewalls from the floor at the rear. Car actually feels solid with no door gap issues.
Thanks |

If you use rubber it will put less stress on the suspension ear.
If you upgrade to bronze or bearings, you should add the plate from foley to ensure you never have any issues. To fix your oval you can weld a washer onto the ear with some grinding of the washer to make it fit flush. |

Or more accurately, it went from not producing any noticeable problem to tearing apart along the lower side of the shaft inboard. Fortunately the shaft nuts were still torqued, so there wasn't any overlong. Haven't checked the other side yet. I have two Porsches up on stands, so this one isn't going to see any welding at present - I do not feel I can do that great a job with the motor in place. So, it is going to be rebushed and put back on the road. Before that, it will get a close inspection at the consoles and ears. I have seen the photos, and appreciate all of the advice. |
