Did it give you a MPH at the 1000'?
That 11.6 is a 14 second 1/4. Where to start... Those coil overs, in the trash, they will beat the mounts out of your car and the leaf is supposed to hold the car up, not the shock.
If it has strong MPH, then there is some positive. If it MPH's like a 14 second car, not good.
