Looking into getting some 10" wides on the rear of my track only sprinter for grip days and just want to know what to lookout for handling wise as I will be changing them back to 8" wides on days. I'll be keeping the 15"x8" -8's on the front all the time, will it cause understeer as the rear will have more rubber on the road than the front?
Another question is, if I get some 15"x8" -45's to fill the massively flared rear guards for drift days how will this affect the handling?
Rim wise I've figured that some 15"x10" -20's will fit without rubbing on the inside as the 15"x8" -8's have about 25-30mm space at the closest point to the inside body, this will mean that this gap will be reduced by 13mm with the 10 wide on it. I'll be getting some large flares for this as they will be protruding 37mm out from the guard.
As far as tyres I’ve found my links to drags have helped with Hoosier making Sports Radials in 23.0x9.5R-15 (item number: 46535) for $441 and Racing Wets in the same size(item number: 44590) for $590, according to the tyre size calculator are slightly larger than my 195/45 15's (+12mm radius, should fit...I think).
I've used the following pages to figure out tyre sizes and rim offsets for you playing at home:

With this I should also be getting about 5.5" of dish goodness!
