I have the 275's on the rear. Different car, I can lock all 4 wheels at anything above 45 mph. Fronts may lock 1 second before the rears but make no mistake if I hit the brake hard enough I am skidding. Make sure you install the fronts shoes also, it take less than 3 minutes, you pull out the long cotter pin on top of the caliper, pop out the old shoe and install the new shoes. I would guess the fronts gave me 45% of the gain I got from the rear if that makes sense. It is a different car stopping wise. After the bedding process I did numerous (15) 100 mph to 40 mph trying to create a braking issue and all that happened was I got a headache from my head flying forward.

SPF has the solution, on a side note I need to give credit where credit is due, one item that has been flawless during my entire ownership of this SPF is the Roush, it just performs perfect day in and day out, I will never own anything else.
