I've seen all SORTS of things 'snap' that may be merely holding..... I don't know.... the AIRBOX onto the chassis. That does NOT mean that the Airbox is altering the handling!

It's rare for the bumper bolts to fail, it's usually the bar itself. Now imagine replacing the bumper with a straightened coat hook. Would you expect THAT never to break in that location or would you also be suggesting that such a break would indicate a bent coat hanger was altering the handling......?

Chris.... you are NOT an idiot.... YOU go and try my suggestion of fitting the bumper to ONE side of the kart and meauring the force you need to apply to it to distort it, let's gues, by an INCH.

Come back and report your findings.....

Being honest, I think you'll find that you CANNOT get the bumper to support ITSELF without drooping more than a whole inch. If the weight of the bumper ON ITS OWN will distort the rubber mountings by MORE than the amount it will EVER be asked to 'resist', then you will be able to see EXACTLY what we are talking about..... we are discussing a P*L*A*C*E*B*O here! It will have about as much effect as CHIN SPOILERS on your crash helmet..... it's a C*O*N!

The Rubber in the mount DESTROYS any torsion-controlling effect!

Even if it was bolted RIGIDLY to the chassis (as bumpers USERD to be) and were made out of THIRTY TWO MILLIMETRE TUBING.... whcih they USED to be.... it would be hard to find much effect!

Just think about how much force it takes to 'rotate' a properly clammped rear-Torsion bar on your chassis compared to that FLOPPY bumper mount of yours. That would imply that a MILLIMETER of change to the setting on yopur torsion bar would SWAMP any HOPE of your rear bumper affecting the kart! The forces are NOT in the same order of MAGNITUDE! The comparison is between an Steel Bar and a PIPE CLEANER!
