How best to reinforce the front sway bar mounts?
My '84 has an uprated front sway bar that, yep, tore one of the front mounts.
Is there an agreed to way to reinforce the mount or kit I should be aware of?
Thanks!

Carl makes one at 928 motorsports https://928motorsports.com/parts/swa...nforcement.php
You could make your own, but for $30 I'd just buy the kit.

All you need is a 10 inch length of 1 inch box section cut at a 45 degree angle around the mid point. The tricky bit is the welding and that is not too difficult.

If you are going to cut and weld on your 928 then at least add some trusses to the sides of the factory mounting points as well.

For those playing along, the best modification is to do it before you need it. If you're stiffening the sway bar or getting an aftermarket piece, get the welding done in advance.
My car has this. Just pieces of flat 1.5" stock that form diagonal braces between the bottom of the mount and the body at a 45 degree angle. That's four bars running from the sides of the mount to the sides of the rail. Welded on each end. On a manual, it's gotta clear the clutch line on the left side.

Come on, people. Stop and look at what is happening, here. Remember to be 5% smarter than what you are trying to fix!
Adding a piece of 1"square tubing (which is impossible to weld on over 1/2 of of its attacment area) MIGHT add support to the entire bracket, but does absolutely nothing to add any strength to the actual captive nuts and metal that holds those nuts......where all sway bars mounts fail.
When was the last time anyone saw the entire bracket moved or ripped off a car (unless it was bottomed out on the bracket?)
The metal surrounding the captive nuts is what fatigues and fails. Note that the nuts are actually "pulled" through that fatigued metal. Welding a support between those two nuts from the backside (a support that one can only attach securely on one side and partially up two of the other sides.... because of welding access) does nothing to add strength to that metal.
The only way to "fix" this area is to "box" in the mount and add thicker metal to the plate where the sway bar sway bar actually attaches.

I'd be looking at those tires closely too.
