like io said ANYONE want to do a interim check, i will do this for zero charge for you, all i ask is you replace the shims i use 
As said before in my case with the high rev use it needs checking yearly, so this has been a real valuvale lesson, in A) not relying on everything your getting from your garage / tuner / dealer ( I'm talking simpsons here BTW) Make sure your getting shim reports and understand what your seeing on your shim reports. B) Do your own fact finding and work if your confident enough to. I now have the knowledge to shim check and i couldnt believe how easy it is, the hysteria behind these is nothing but that..... Hype. Anyone on here could do this...
however it took me too long to do this but again was being overly careful and still managed to loose a nut down on the under tray!!
