Was wondering if anyone has tried to put Bullitt springs on their V6 mustang. If not, what do you think about putting those on, would they work, and would they drop the car noticeably?
The Bullitt springs shouldn't be used for lowering a car, since they only drop the car about 1/2" over stock, and they shouldn't be put on a V6, since their spring rate is calibrated for the heavier V8 engine in the front.
A number of companies carry springs that will drop a V6 about 1". That's about where you want it- gets rid of the 4x4 look, but won't require castor/camber plates or look too "slammed". Their spring rate will be correct for the V6, too.

V6's can benefit from higher spring rates, just like any Mustang can. However, the stock spring rate on a V6 is significantly lower than the 600lb/in (front) Bullitt springs, so the stock dampers won't offer sufficient damping to take advantage of the higher spring rate. Then again, the same could be said for putting Bullitt springs on a stock GT.
Overall, you need to consider your goal... Are you going for looks or performance. If you're wanting the slammed look... the Bullitt springs aren't going to do it for you. On the other hand, if you want to add handling w/o a large drop, look for the Bullitt suspension kit which will come with the springs, Tokico shocks/struts, and sway bars.
