300/300 seems pretty low even!

Strange that you should say that, I'm at my tire/alignment shop getting the camber done all around on the car and have 265's on. -3 degrees front and -1.5 rear. White line rear camber and 2x Eibach each side front.

 

They use a mustang dyno... so add to those numbers for a dynojet type number

And I also thought it made a bit more power than that at one point... maybe I'm wrong.

 

Well it's increase over stock when using a mustang. I'd like to know what the baseline was on the car they got 300/300.

 

Car is down at least 300-400 lbs from stock too.
