I believe I will try the solid mounts and see what I get. When spring gets here (and the white stuff disappears), I will be able to report back.

Have a Happy New Year all

Sounds like you will have a busy two weeks during spring and summer.

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 put them on Erik's car. He seemed to like them. Very positive steering feel. I imagine the one negative is picking up some additional road noise and vibration.

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...

Has anybody tried to reach out to Hamburg Technic and let them know the market for all the stuff they are producing IF it was of good quality?

No need to, one of our vendors is selling a crap load of this stuff. At 3x what it is being paid for. When you can buy one item for $30.00, and people typically need two of them, and sell them for $189.00, you are banking.

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.
