straightened and repainted the rear bumper, its not "perfect" anymore...but most people will never notice, I will...but just going to have to live with it until I chance upon one that is better, which ya'll know isn't easy to find....I am still very amazed at how it withstood that impact, how the car managed to escape panel damage and at how i managed to collect my senses enough to not get myself put in jail...

If the steering wheel shakes it's a tire nine times out of ten.

Did you tighten the thread adapters properly on the rack setup? Cause I have the same one and have no issues at all. I bought mine when Mr. Waits still owned RE-Speed though so I don't know if that matters or not. I didn't feel like reading that thread you posted.

First of all, I gotta say congrads on this build!
Wish I could see it in person for myself...

Gotta love the link to the dumb club...
(Bent axle shaft? Are you for real?)
Only really useful info was the sheer pin reply.
Gotta narrow down the problem to either a resonance problem (which is sounds like) or a out-of-spec part (which would usually mean +speed = +noise, which doesn't sound like the case).
Let's concentrate on this as a resonance problem...

Do you know what your caster spec is?
Too little caster can cause your headaches.
Another more than 5-degrees should be okay - I would worry of caster is less than 5-degrees.
Since you basically did a front steering / suspension retrofit and others have complained about the same problem, I would tend to blame the retrofit itself as the problem...

thanks a lot!
ok alignment specs, my caster L=3.1, R=3.8, with a specified range of 3.2-4.2 and 3.7-4.7 respectively, so it is pretty much in factory spec range, that is where we put it since it was all new of course and totally out of whack, so that is where we go from here on that.

I have to pull the lower steering knuckle off since the trip to DGRR had long sustained periods of vibration on the interstate it has worked a little slop in the spline, and it is as tight as the little bolt will go, so it needs to be looked at and possibly replaced.... who knows, but such is life, in the process i also had my upper intercooler bracket bolt break and the drivers charge pipe rubbed the sheet metal and put a small hole in the pipe...so gotta fix that too...FUN!!
considering the abuse i hurled at it on its maiden voyage and the vibration problem it left home with, that isnt too bad.

also along the way i bagged me a c5 corvette, a 5.7 GTO and a 6.0 GTO on the interstate that thought they wanted a piece of my lil ol rx7, aint surprises a bitch

Looking forward to doing that again, with a more refined tune, more power and better tires...oh that and a ^&$##$*&@^%$( GPS.....

Stock FC caster is 4-degrees, 40' - almost 5-degrees.
Kingpin angle is about 13.5-degrees.

Can you induce more caster with your set-up?
