1983 Oldsmobile Cutlass Supreme Sedan LS Turbo Build

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! 😆

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).

Are you running stock lower arms?

No sir. I have these, pretty beefy:

Well, I pulled the trigger:

Now I can feel a little better about going so fast!
