Spohn Performance billet strut mounts!
I'm pleased to announce that Spohn performance is now going to be carrying the Alloy specialties billet strut mounts that we manufacture. These are the same ones you have seen discussed in in the recent strut mount thread.
The mounts come fully polished and feature a Teflon coated replaceable bearing. We have also built an extra 1/4" of negative camber adjustment into the mounts. The top of the mount is radiused both inside and out to prevent stress cracks from starting, and to provide a cleaner look. The mounts are fully CNC machined from 6061 billet aluminum and are professionally tig welded on the top and bottom by a certified welder, then professionally polished to a very high shine. The Spohn part number on these is 951 and they are $350 per set.
For more info you can contact Steve Spohn at 717-335-3356, or post questions here and I'll be happy to try and answer them.
Thanks
Dan

HO ****! Thats good news to hear. I always wanted your guys strut mounts but never picked them up becuase I wanted more camber adjustment. But now that I can adjust it more with yours I'll be picking up a set sometime soon.

If things work out, we have another product Steve and I will be offering. There is just one techinical problem we need to work out before annoucing it.
Stay tuned!

Do you offer these in different heights like Hunter Motorsports did. This way those of us with lowered cars will not lose any suspension travel. Besides being so much more heavy duty, I think getting full suspension travel is the key selling point to me.

They are available in medium height as pictured. This will work for lowered cars to prevent the struts from bottoming out.

They will work just like the stock mounts. I've got them on my car, and it's not lowered. They just give you more strut travel before the mount bottoms out which is a good thing.

Looks nice. What years are they for? The retainer on 82-86 is different then 87-92. The rear stud is closer to the strut on the 87-92 style.

i was just busting on you alloy, but i wouldn't mind knowing what code your welder is certified to, not that it would apply to your parts ,but it's a good selling point. WPS is weld procedure specifaction, basically all the parameters used in the welding spec certified to and/or used in a specific application. parts look good, good luck with selling them.

Timz2882:
The strut mounts will not lower you car in any way. Springs and drop spindles perform that function. As I said, these mounts give your front struts more travel before bottoming out on a stock, or lowered car.
ede: I'm going to drop some mounts off for welding tomorrow, and if the owner is there I'll try and get the answers to your questions then.

Where do you purchase just the bearings?
Also, I'm not sure I fully understand the differences between 82-86 and 87-92.
The slots are larger? Why can't one plate be made to fit both sets of years?

if you look at the retainer that the strut mount bolts to, you'd be able to see that the 82-86 pieces are different than the 87-92 pieces.
i think one of the studs on the retainer on the 87-92 models is actually angled closer to the strut for increased adjustability.
someone posted a link showing the differences earlier in this thread.

Well if that isn't annoying.
Wouldn't it be possible for Spohn to make the strut mount slots wider/larger to accomidate the different angle or difference in lengths of the bolts instead of making each bottom plate different?

It's much easier to just pick up a set up used retainers from a newer 3rd gen. When I was designing these mounts, I picked up a set of retainers at a local wrecking yard for next to nothing as I recall.

alloy, when you say medium height does that mean the bearing is higher or lower than the factory height. Also to get the extra camber adjustment did which direction did you elongate the slots and how much? thanks, josh

He means that the bearing is located higher up as the mount tube is longer on the medium height mounts, and even longer on the race/max lowered mounts, giving the strut the increased travel it would need on lowered cars.

It is becoming harder and harder to find parts for my bastard child (expecially interior/exterior).. I can't even find an aftermarket wonderbar that fits right..

when I was looking for one I didn't want that design I wanted a tubular bmr or spohn design with the thicker mounting plates and somewhat more robust design..
got one from bmr and it didn't fit, the swaybar mounting points are just a bit different on the 1982 year cars.. again a matter of 1/2-3/4 of an inch. On Spohn's website it actually states will not fit 1982 TA or 1989 TTA..

bigger tire, more horsepower, I don't care about an extra 1/2 pound, I care about flex and strength..
Even with the wonderbar our frames are still flexing away with big tires..
trying to point out some 82 design differences not defend my performance philosophy..

you pointed it out. I questioned it. i do not buy into the bigger is better theory here. it is a support for the steering box, i firmly beleive even the stock one, is more than up to the task of supporting the stress put there by the box.

you can watch the steering box area bend even with a wonderbar there, I have watched it on many a thirdgen, a wonderbar helps but it is a bandaid not a solution..there are some very real stresses put on that area not by the box but the tires, suspension and the road..the only real solution is to wonderbar it then weld a piece of plate steel behind the box area.. with your car in the driveway have someone turn the wheel and watch things flex.. our subframes are thin and cheap, cost cutting.
I am not sure what I pointed out other than the 82 is a different design and that the wonderbar that I would prefer to use is not available and niether are the strut mounts (without modification)..
sorry alloy, this diatribe has lasted longer than it should of..
