Battery is upfront, its still a street car and I dont want a switch until its not. I checked the rear shocks and they are about an inch longer than what the rear end hangs fully extended. I have a low first gear in the 904 in the car so I am not sure a gear change will matter, with the tire I have I am turning ove4 5500 at the stripe so there isn't a long way to go. I am pretty happy with the car overall but looking for information as how to tune the chassis to improve my 60'.
