IIRC(and I am not an expert either, man...)
The Turbo is not off the wall.. infact there is one being offered, for the tours... however you can't run more than about 9#, I believe...
RWD? ouch.. not going there.
Oh.. BTW.. tours use either
19-21, or maybe its is 17-19, for tour's and SVT's, respectively.. Look in to it, to get the right set, I don't know for sure.
Do a little research.. weed man...
