I saw that too. Fontana is really not any better than the street in front of your house. A low 7 second leaf spring car is not going to be the most consistent car, thats why people put back half and four link their cars. :D Been there done that.
I think at this point I am going to keep the link I have and move the upper bars off the pumpkin and out to the frame rails like USSG did his uppers. This will allow me to move the Shocks to the rear of the axle instead of in front. I will also put some extra adjustment holes in the lower brackets at the Axle for more tuning capability along with buying or making some shock mounts with seven or eight adjustment holes so I can drop the car all the way down if I want to.
Like you keep telling me I need to get the NA thought process out of my head. Those 6 & 7 Second Turbo Cars leave the line like a Stop Light and then come on like a couple locamotive's after the 60' mark. The rear ends on most do not even get that much of a Hit & don't move or drop the rear of the car if any at all. I am amazed at how soft they come out of the hole at around 3500-4000rpm it seems. Some even alot less than that.
