I have been racing a 2009 XK for over a year. Mostly in AutoCross and some HPDE NASA Training courses. Last race I believe I busted a transmission Extension mount. The symptom was only revealed under severe cornering and typical for AutoX. There was a definite "Clunk" and a loss of the usual perfect suspension control. Everything returns to normal when not under such duress, but I was wondering if this was a common or unique experience. Racer responses appreciated. Also anyone experienced any other "Weak Points" in this model or XK's in general that I should be aware of? There is no local Jaguar racing experience I can find here in Louisiana.

 

Maybe try the right forum...
