too true. I have managed to do a lot of my own work up to now on cars and bikes and I enjoy it. The dif would be a differnt ball of wax which is fine but it would carry a big penalty if I got it wrong. That said, if it proves the the most cost effective option then that is probably where i'll end up- and for the better ultimately.
Is there any machining that needs to be done to install the wavetrac or quaife? I some machining experience but it's pretty limited.
