Wing mount bracket failure
 
So woke up this morning to a glorious day, had to go into work sadly but used it as a good excuse to do a much longer trip in the marlin, 30 miles each way mostly through country roads, at parts the road was really bumpy and I could see the front wings bouncing all over the place, even with an additional brace welded in by marlin, anyway just as I was coming down my street on my return I heard a bit of a fibre glass clunck from the front driver side wheel. I thought the bolts holding the wing on had lost their nuts but it's pretty obvious what the culprit is! See below:

As you can see the failure is through the 5mm flat bar straight through the centre of a bolt hole holding on a p clip. Coincidently this may also be a spot that I tweaked and bent the bracket slightly to get the bracket to fit better.

Easily fixable and I will redesign with out a hole through the centre of the bracket. Has any one else redesigned the front brackets to stop the wobble and if so pictures would be much appreciated!

I both changed the wing mounts and swapped the wings for much lighter carbon fibre one

Some pics from a recent minor restoration:

My original wing stays were hollow steel which cracked after only a short time. I replaced that with solid and adjusted the angles. That combined with the massive weight reduction has made it much better. They still wobble but it's not too bad.

I didn't have any problem with my wing stays up until the time I sold the car 5000+ miles. But I did a few things to help.
1. The wing stays passed through a slot in the wings.
2. I was very careful to minimise any bending of the wing stays.
3. I doubled up the fixings to the upright. Probably different to yours anyway as my car was E 30 based
