87 911 Cab Sway bar mounts cracked

Need some input here. My friend has a 1987 911 Cab, garage queen, no hard driving. He has cracked the passenger side sway bar mount twice. The mount was welded back together after the first separation. I know the fix is not as strong as the original but I cant figure how he keeps doing this. I have seen this happen on race and DE cars but never on a street car especially the way he drives . Any specific model year problems? alignment? corner balance? anyone else experience this?. thanx in advance
Scott

I had the same thing happen on my 1987 Coupe. From what I have read, it appears to be a common problem with the original sway bar mounts. The fix is to have the old mounts removed (ground off) and new upgraded mounts welded back in place. The new mounts are reinforced on the back side and less prone to cracking. I had my local shop do the work for around $500 for both rear mounts.

Do you think years of stress just fatigue the mount? Even easy driving? The repair I am familiar with but I am wondering if it could be the result of something else causing excessive stress on the mount. Its definitely not his driving.

It's the original mounts - very weak design and they can break even with normal driving. I first did the factory replacement with the reinforcing panel, but tore that out too. Second round was the same mount with the Smart Racing reinforcement kit added (did that on both sides). So far so good. If I ever have to do it again I would definitely use the Wevo cast steel mount.

It's called better tire technology and wider wheels. I've torn mine out too - they should definitely be on the once every six months check for cracks list.
