I am thinking along this line too. In the original design this bolt only carried the shock absorber. In my situation it carries the coil-over shock unit. Knowing the weakness of the upper mount we reinforced it so much it could carry two Fs. The conversion has done 15,000km and the only dramas have been these bolts. After the first breakage we replaced all of them with super high tensile bolts to aircraft specs at about $100.00 (60 quid) a piece.
So. If I get you right, the coilover is still attached by this bolt that holds the standard damper?
If so, I'm not surprised it has failed. It's a long bolt only supported at one end. It's not designed to take the strain of changing from spheres to coilovers.
I would think it needs to be supported on both sides of the damper bottom fixing.
The passenger side always gets more stress as the nearside of the road normally has more lumps bumps and debris than the centre.What I am surprised at though is that we got 15,000km out of the driver side but so little on the passenger side. After the first breakage I decided that a complete bolt change would be done ever 10,000km as a precaution....
I also am very interested in the Suplex kit being marketed by B&G.
As I wil be over in the UK next month I was planning to visit them a have a .closer look.
I am not worried about my turrets as they were ripped out when I put adjustable shocks and PU bushes on some five years ago.
In fact my turrets were reinforced as per the X power racing guide and I think when my F goes to the wreckers the rear turrets will be the only thing that survives.
Will be very interested in your experience if you go down that route and if you can get hold of our September issue of Wheel Spin our club publication you will find the report refered to in above posts.
