You can’t adjust them to be squishy?

I thought mine rode better with the Vikings than the stock junkers when adjusted to the extremely gooey setting.
I have them on the softest settings for the street. 200 psi springs as well. These aren’t made for comfort 🤣🤣

200# springs!? I can't imagine my car with springs that stiff.

I was told these were the ones I needed. Guess I didn't know how it would effect normal driving, but I will get used to it.

Bottom 9s, here I come (I hope!)

How much are the springs compressed? A spring that stiff won't extend very well for a radial, and will crush a slick. The problem with having too stiff of a spring is u can never make it act softer. If u have a soft spring you can always make it act stiffer with valving.
See what happens and see how it works and adjust from there. How hard do u leave? What kinda 60' do you cut?
Fwiw I run a 125# spring, a 110# would probably be better.

Trick Chassis recommended 200# cause I street drive it a lot (and the weight of the car). He said 175# would be better for the track. I can always swap them out to adjust in the future. Overall length of the coilover is 14" so I am not sure how much the spring itself is compressed.

I typically leave at 3000-3500 rpm, 4 psi on the trans brake. Best 60' with the old suspension combo was 1.48.

What does the car weigh race weight and street trim with the whole family in it? A lot of that is again a compromise.

My wagon has 175-200lbs of spring in the back and it carts around three kids (two are mine) and two adults (one the jury is still out on) just fine. I wouldn't change it for all the 60' times in the world.

Race weight and street trim are the same! :LOL:

3840 lbs with me in the car. More with the kids and family. Could also be the valving in the shocks. Crusader (I have) vs Warrior (standard).
