Mark,

Again, thanks for taking the time. I only did one more iteration and posted it to give you a better idea where I was. As I said I am not going to use the MII spindles in many more iterations until I can give the AFX spindles a go. The above setup is with a 19" lower and 10.5" upper and a FVSA of 124". This is considerably better than when I had the 8.5" upper.

All this being said, I understand exactly what you are saying. I have known for a long time that the best setup for a particular vehicle and situation is always a compromise. To be perfectly honest the ratio of good-guys type event vs. track days is going to be 100:1. So looking good is very high on the list and I think anything that can be done along these lines is going to be a vast improvement over putting dropped spindles and lowering srings on the stock front end.

As soon as I get some info on the AFX deals I am going to do some more refining. I'm going to try a 17 lower and 9+- on top to help with packaging issues.

With regard to the RC height, I think I want to stay above ground. This being a truck, even significantly lowered it will still have a CG around 20-22 inches.

I was going to model a hub that uses the impala bearings and would mount on the impala nose circle track spindle with a 5 on 4.75" bolt pattern. I have a friend with some nice cnc turning centers. Some chunks of 4340 material and some machine time should solve some of the issues with the circle track spindles. We'll see.

On a side note, what do you rate your 3 link setup for power wise? I ran 3 links exclusively on my race cars. They are tremendous. I haven't done the calculations on pull in the 3rd bar yet, but this truck is going to have 700-1000 hp depending on alot of factors. I know a truck on street tires will never put this much down, but we are still looking at significant forces. I can package alot under a pick-up bed. I'm either going with a 3 link or triangulated 4 bar. Comments. I can make either of these work.

Thanks again Mark.

Chad
