Rather than welding the upper coilover mount into the channel I am considering welding it to a plate set that sandwiches the channel ang bolting it through. I think i will bounce this off DSE before I do it but I dont see a reason why not. My reasoning is that if i am fortunate enough i will get a lot of road miles on the car and i dont think that upper bracket is up to that without wearing/deforming.

Are you just trying to reinforce the upper mount?

The channel as designed by DSE will take some pretty good abuse without deforming. Many people track their cars pretty hard without issues.

There are thousands of these out there and I have never seen a single failure of the type you mention. Surely ex GM engineers can design a product that does not need to be re-engineered....

That's what I would think too but this upper bracket is the lightest piece in the setup and it will be in the worst place to replace should Pa potholes do what I think they will. I think this thing is great for cruise night, good for autoX, not so much for over the road and potholes.

If you want to worry about something worry about the 50 year old thin gauge sheet metal frame rails in these cars... :smile2: Did you minitub it? If so the frame rails were likely further weakened...

If you feel that the bracket is not strong enough, I would suggest fabricating four little “L” brackets that can be welded to the sides of the existing DSE shock mount. A fabricated bracket would have a hole drilled on one side. The drilled hole is for the shock mounting bolt. Place the brackets on the outer sides of the existing DSE bracket. The extra “L” brackets will provide thicker metal for the shock mounting bolt and more surface area to weld to the trunk mounted C channel. I think the shock mounting bolt is long enough to go through a thicker shock mounting assembly.

I would not try to fabricate a completely new bracket since the DSE bracket has a sleeve bushing welded to one side of the bracket.

Oh yeah Don, its minitubbed. Only an optimist would call that a frame back there. I would think that a minitub job could weaken the back a bit but the formed channel that goes in with the quadralink sorta firms up that whole section a bit so it can fall out as a unit. A great place to tie a cage on but I am not doing that.
I like your gusset idea Patrick.
