DanEC Dan The best way to start this is to set the ride height at 5" front and back of car frame. Measurement is behind the front wheel at the frame and in front of the rear wheels at the frame. ERA sell their cars with top of the line shocks and springs. In 10 years my era with the stock springs and shock didn't drop 1/4". Put some milage on the car and get an alignment done. After about 500 miles of breakin, have the car weighted for corner weights and maybe drop it another 1/2" to get the correct look you want. Track car runs at 4" with 30% higher rate springs on it. Get some miles first and then start to play with.
