standard guards & narrow springs +40 to +50 offsets work on a 7" rim 2" wider i have 8" wide & +6 offset yet to see how much more can be squeezed under the rear but i think my mounting face is further out than stock on the rear now so it wouldnt help
oh, those 7s fit VERY close to the spring around 3mm, slight decrease in steering angle before rubbing the body, the 8s however have about 20-30mm before spring, makes a decent diference to the turning circle id imagine, not sure what stock was like in comparison though, sorry, that may help though
