Koni yellow's
 

Does anyone have the single adjustable on the front of their car? Does that have the lower perch or do I need to get double adjustable? Thanks.

I had the single adj on my car it does have the lower mount for the spring mount.

Thanks. Did you switch out for double adjustable or something different?

As the car was getting faster and handling better The front springs went from 500 to 650.To 850 When I put the 13inch wide hoosiers on the car. A koni yellow can only handle a 650lbs spring. So now the car has a custom valved DA penskes on all four corners. Front springs are in the 1200lbs range and 450lbs in the rear.

That's some serious spring. How come so stiff? If it's to combat body roll, I suppose you tried stiffer sway bars?

with 13 inch rubber all the way around the car has tons of grip, so there are two was to combat body roll, springs or big bars, my car is kind of mixture it has factory bars 35mm/24mm. The car still has some decent roll but the tire stays in the camber curve

What do you think of your shock/spring combo and drag racing? What's the 60 ft for those times?
