I have been facing some oversteer issues recently that I think might be related to aging rear suspension bits. Has anyone noticed this on their aging track cars?
My situation is as follows. 2009 with 75k miles. Lots of track miles I am experiencing mid corner to exit oversteer that I didn't have in the past. My general setup hasn't changed (alignment, tire pressures, spring rates all have been optimized based on tire temps and pressures). Three years ago I added solid subframe, differential, and the below rear camber arm bearings from bimmerworld. http://www.bimmerworld.com/BimmerWor...aring-Kit.html Are there any other bushings in the rear of the car to check? Everything looks good visually but the car just doesn't feel stable in the rear. Bimmerworld also has these bushings that I might try. http://www.bimmerworld.com/Suspensio...ing-Set_2.html Comments and thoughts? |

There's also the "camber arm" bearing set...
http://www.bimmerworld.com/Suspensio...aring-Kit.html I don't have enough track miles to see where things are wearing out. My engine and electronics seem to all be going Bosch on me much more quickly. |

I've been pondering the same thing myself. Not necessarily dealing with an undesired effect here, but wondering how often I should have the alignment checked... there's some frustrating discussion from time to time, but nobody has come up with a track service interval for these suspension bushings.

The trailing link bushings were in good shape at the time (and didn't have any labor savings with the subframe) so I left them in. I called bimmerworld today and it sounds like the symptoms I'm having are related to the the trailing link bushings. |

My race shop and the dealer's Corvette tech have suggested checking it once a year, especially if you are the kind of person who uses all of the curbing and hits the apex curbs.

Interesting, I've never heard of toe plates. I saw the instructions on longacre's website, but I don't 100% understand. What are you measuring to on the back side?
