Copying from my facebook thread I started:
I was driving back from the Tail of the Dragon to my hotel and it started to rain hard (again). The kind of rain where you can barely see anything. I slowed her down and I noticed the car was darting all over the place. I wasn't sure at the time if it was the rain or the damn alignment slipped again. Luckily, I was on my way to the enclosed trailer to pack her up to home anyway.
I have been chasing a problem on the RX-7 for the last 5 years. The car has always felt a little unsettled on our craptastic WI roads. The alignment has been bumped or forced out of alignment on at least 3 occasions. I believe it happened again at the Tail of the Dragon. That could have resulted in bad things if it slipped anymore than it did.
I found one end link stud (Samberg) was actually BENT and one of the caster/camber bolts slipped out of position. (I took pics of them after my 3rd trip to the alignment shop) Also carved out a piece of steel to brace any alignment slipping and tacked it into place.
Replaced both end link studs, tested for bump steer, and did an old school alignment. (I'm actually getting good at this now LOL)
Took the car for a test drive and it has NEVER felt so planted and sure-footed over crappy roads. I have actually changed tire sizes (taller sidewall) because of this issue. I questioned my coilovers being too stiff. Nope! Just incorrectly corrected bump steer.
