Expanding this thread a bit ... I see 928 Motorsports are selling solid steering rack mounts.
Benefits of these, as I view, they should never wear out.
Anyone tried them? Positives, negatives when compared to the rubber, the Delrin bushings?
Just getting ready to do mine and am seriously considering the solid ones but would appreciate other's experience on this.
Thanks

We sell about one set of aluminium bushings to ten sets of delrin bushes. Both types are the eight piece set to ensure no up and down movement of the rack. Both the same price at $72 a set.
Hundreds of delrin sets installed over the last few years with zero issues or wear.
If you have a good set of original bushes and change to delrin the improvement would be small.
I have seen that Hamburg Technic is now producing an aftermarket copy of the original rubber bushes - I hope they don't go the same was as all there other products.

I have a set of Carl's aluminum rack mounts on the GT, as the delrin weren't available yet, and I have the split delrins on the stroker. Perhaps I'm just not tuned into what I'm supposed to feel, but I can't tell the difference between the two in terms of steering feel. Either is a big improvement from degraded, oil-soaked rubber...

Can't tell you how many of my customers have bought this stuff w/o checking good sources, and getting a nice surprise when I won't install it.

I have never noticed an increase in road vibration in the steering wheel as a result of solid mounting the steering rack. No surprise, really, given the round rubber isolator disk that is in the steering column. On LHD cars, look down below your power brake booster and you will see it in the steering column.
The big gain in getting rid of your soggy, soft old steering rack mounts is in quickness and accuracy of turn-in when driving. When the rack is loosly mounted and you turn the steering wheel, the rack first must move on its mounts until it can move no more before the tie rods can start to make the tires change direction. Solid mounts remove this delay, and positive and quicker steering response is the result.
