Fixed Banging BadZ PHR...
I went to the hardware store and bought 14x70mm Grade 8 bolts, washers, and flanged nuts. The bushings I had were a perfect fit onto this bolts. Also, the larger end of the stock stepped PHR bolt is 14mm. So I then had to drill out the one smaller hole to fit the bolt through. Bolted it up with few issues. Then I wrapped the bushings with electritians tape to prevent any banging from the rotation of the PHR. I haven't fully tested it yet, but over a couple spots in my driveway it was silent, no banging.
I'm so much happier with my Spohn pieces...I don't even know why I got rod/rod parts. I daily drive the car, and it rarely ever sees the track. The poly was a much better bet.
The bolt is stepped. There is about 1" of the larger step which is unthreaded. The smaller step is about 1.75" long, and there is 1/2" of it that's not threaded. The bolt says '10.9' on the head. The end of the bolt is chamfered at about 45 degrees.
The bushings I was sent, twice, had an I.D. that was too small for the large step, and too big for the small step. You need a make two sizes of bushings, since the bolt is not a constant diameter.
Thanks for looking into this problem.
