Default Needs ideas on improving eBay Strut Bar Mounts

So I bought a set of ebay strut bars with the intent to improve/play with them with my mig welder.

The bars I think are fine (not the most ideal, but given the dimentions of the engine bay, will work fine).



I'm not sure what I could do to the rear mounts, but for starters the front mounts I can see improvement on:

1. The holes that the bar bolts to have ALOT of slack. thinking of welding over and drilling new holes that are the same diameter as the bolt.

or instead...

2. The 'ring' that bolts to the strut/fender is fine, but I was thinking of cutting off the 'mounts' and making/welding new ones on like these:

A) Has horizontal brace between vertical braces.
B) Only verical braces, but since the force will be linear, thought this would be fine.

If the holes are to big, why not remove al the paint, mount it, and then weld some rings onto the mounting plate, then repaint.
Saves you from drilling holes/filling the mounts.



The black parts are the holes that are too large, the red are normal stainless rings you put under a nut.

Edit, reading owns me, the ring is fine, the other bolts are not
But I am keeping the drawing in here, som anybody who has a bar where the ring is not good can see what i mean
(Also to display my wicked paint skills)

Also, make a clamping construction in the middle, so you can triangulate it to the mount where the factory dogbone goes.
If you can weld Aluminum you could also weld it.

Yeah, that was the idea I had in mind, but I just ended up making all new mounting points, so I'll have to drill my own holes.

Eh, I'd need two additional bars to go to the firewall to triangle it, and there isn't a whole lot of extra room with the A/C lines in place.

I'd given this some thought too. Personally I would just get some lower gauge steel brackets and weld them right onto the chassis near the strut towers. Make sure they have a decently large base so there is less chance of stress points.

Find some strut bars that have the correct length and are also adjustable. Discard the old mounts and just mount the bar to your welded brackets. Of course just remember to paint. Then you'll have a much stronger base.

I'm still not too hot about having brackets that can't be removed, but I'm also weary that those ebay brackets will bend enough to not even do a damn thing about stiffening up the chassis.

FWIW I still think those tower strut bars are more for engine dress up than anything else. Suspension and rigidity can be have more worthwhile improvements elsewhere.

I thought about it, but I'm not ready to weld to my chassis yet...

I have finished 1 rear mount though Paint is drying now. Still need to finish the other 3

+1 This is being WAY over thought. Unless your car is going to be doing some serious competition tracking your wasting time and energy for zero gains.

I agree with quazimoto. I bought these cheapo and I did not use the bolts supplied cuz they were not fitting right. I went to hardware store and bought some huge allenhead bolts that fit super snug and called it good. And they are black so that's gotta add some HP.
But fabbing stuff is so damn fun.

for the type of stress, boxing that top makes no real difference.

I have had both the ebay bars and the good bars (Cusco) and the good bars do make a difference in turn in chassis strength so the OP modding the ebay bars to make them stronger is not a waste of time. Good bars are far more then just "engine dress up".
I will always run good upper strut braces on my cars, its a good improvement and keeps chassis flex down.
