the Dr Diff is a nice piece of kit, no bones about that. and it's a great value if you need everything, as in starting from scratch.
the stock "small" 10.8's would even be just fine on the street and for "spirited driving". one thing to keep in mind is that the 11.75's are HHHEEEEAAAAVYYYY.
anyway, my point was more to that you've already got the stuff, so why not just use it and save yourself a few doubloons.
