[That looks to be a poor design flaw

[Edited on 25-8-09 by mangogrooveworkshop]

looking at those photos, it look slike just about every weld failed. i wonder if he's actually hit something linstead...

Oh yes very poor , What no gussets! those plonkers.

Mike

Tut tut bolt in single shear as well not good practice.. Not surprised it went like that at the weld boundary lots of stress at that point..

Dan

Perhaps we should offer our services to Caterham.... Flak could do the sums

To be fare though looks like they revised the design a lot, also when it fails it looks like it still stays in one bit witch is helpful!!

I think thats the old design. They had a few failures years ago so revised the design. If yours failed it got fixed free of charge.

I thought you meant Tiger Cat owners...

I hope I never find out - i've got my own de-dion going on my car........

luckily the shock mount is nothing like that & i've no intention of ever running more than 150 bhp (starting out with 86 of henry fords finest crossflow ones).

Good point tho - there is a caterham owners at work, i'll point them at the thread.
