Thats why I go and test her out in the paddocks under "controlled conditions"
before taking her into the hard stuff.
You always have to prepare your vehicle for the worst and its that 1 time that the front end comes down harder than normal that you find out if you or your suspension bloke have set the front up correctly.
KTM, Rod is right in whats he's saying. Looking at the pics above, before I fitted the spacers, the suspension was "almost" fully compressed, how much more compression there would have been I wasnt too sure but the coils were very close together and the bump stop was "just" touching the LCA.
My main concern for the bump stop spacer was to stop the tyre carving up the guards like a chainsaw, but it is also a small safety buffer for the strut.
If you strut is bottoming out under full compression and you jump underneath and check the clearance between the bump stop and the LCA and there is some, then your in trouble. the bump stop NEEDS to bottom out before the strut does.
This is where coil spacer on top of the strut are a dangerous proposition if you 'wheel' your fourby and not just "mall crawling" it.
The factory strut has a pre determined internal stop position. By placing a 25mm or more spacer on top you are pushing the limits of the stopper inside the strut by that amount, therefore when you come down hard on the front suspension your strut is going to bottom out (insert coil spacer thickness here) earlier than the bumpstop. High probability of the strut collapsing and pulling your driveshaft and front diff internal out with it.
10K had some pics of his strut failing a while back....wasnt due to these spacer, but the bottom of the strut broke, and pulled out his front diff internals along with the driveshaft. You dont want to be in the middle of woop woop when that happens.
So if you got a coil spacer ontop of the strut, I suggest you go and test out the front suspension flex and bump stop location and see if it needs extending or if you need to replace the whole front strut with a longer one in its place, coz it could save ya heaps of cash and heartache in the long run.
