1/4 times shouldn't ever be a goal for a DD Focus. It's a small, light FWD car that with the right mods can be a great car to take out to a windy road on the weekend.
I understand that, just dynos and 1/4 mile are the easiest way to measure an increase in performance. I just purchased a mess of suspension parts for the car as well, and i dont plan on ever taking it to the 1/4, thats what my other car is for.
how do the cams effect the driveability and fuel economy on the 2.3? would it be better to do a stage 1?
