Quote: Looking back at this post you initially said "...He said that for drag radials to work the rear needs to come up slow when you push it down."
That is 100% correct for drag radials. I got my AFCO's and had the valving reworked for drag radials. I believe I paid almost $700 shipped getting them from Mark Menscer. They work like a champ! I went 1.42 a few Fridays ago and believe I have some mid 1.3's with a little more boost and a boost controller.

I did call him. He said $850. Originally he said I could use stock Strange shocks based on my ET. When I told him the weight and horsepower of my car he said they won't work I need a custom valve AFCO.
