Re: convo pro and backspacing requirements (munday)
Was looking in the Convo Pros a while back not sure about the backspacing but you will probably need offset trailing arms for 10 inch wheel, Not sure if anyone is getting away with 10 in rim and stock trailing arm, at least I am not aware of it. That is the first thing you have to check out as the trailing arm swap is a fairly big job and gets into a few bucks.
Would be interested to lnow if anyone was running 10 x 15's on stcok trailing arm though.

Re: convo pro and backspacing requirements (munday)
I run 15 x 4 Convo Pro Skinnies and 15 x 8.5 Convo Pros with ET Street tires at the rear.. The Convo Pro rims come with either 3.375 or 4.875 inch backspacing.. 15 x 10 inch rims with 3.375 inch backspacing will stick out by over 1.5 inches.. If you go with 4.875 inch backspacing.. you'll have to go with offset trailing arms and you couldn't go with too wide tires because they would rub against the frame...
Like I said above.. The 15 x 10 Convo Pro rim with 3.375 inch backspacing would clear the trailing arm easily but would stick out. The one with 4.875 inch will very likely NOT clear the trailing arm.. Well - the wheel will.. but the tire would rub against the trailing arm..
