While I don't have a BDR, the 255 x 60 x 15 fronts do a very nice job of filling up the front wheel well on an SPF and give the car an excellent look and stance.
Depending on how torquey your engine is down low, you might want to get the biggest tires you can fit in the back. Back tires tend to be consumables (as I suspect you have long known) so sticky consumables are better than not so sticky consumables.
While not the stickiest this tire is still a good compromise between sticky, handling and some tire life on the street. The tire is the Nitto NT555R 325 x 50 x 15 rear tire. Jegs has them for $213 right now which is a pretty good buy. Here is a link to the tire on Jegs; click here =>
