If you were happy with the ride I wouldn’t mess with it.

Is this the same shop that rebuilt your SBC?

yes, it is the same shop. They are just about done with it and just finishing up some small details and figuring out the suspension. Car felt more like a boat than a race car when I had it before. then again, the shock was blown so it is hard for me to say either way.

That is more spring than I would want for something I was going to drive a lot. It is also more spring than I would want with 275s in the front. The 69 we have with 315/335 is running 650/400 and the tiny 3/4" rear sway bar and it works well. JJ also did the shocks on that car.

Also worth noting, DSE has updated the upper control arms since your subframe was built. There is more caster built into them now.

To add on to that, if you trust the shop you are working with, and they have taken the time to know you and understand your goals for the car, then let them do their thing.

If you want more opinions, call JJ at Ultimate and see what he thinks.

When did they revise the control arms?

For what it's worth, i'd have to dig up what's on the rear of my car, but i know the fronts are 650lb/in. Mine is a 427 LSX block and twin turbo so a LOT of weight on the front. I'd think 800lb/in would be very high for a SBC.

I went from my old non adjustable 450lbs to 550 Jr I single and my car handles amazing with that setup. I’m still running the 250lb rear spring. My buddy has a set of non adjustable a laying around that he might sell you for the same subframe and Quadra link. If you want a great ride and handle well just go with the single adjustable 550 and 250 springs. If you want to race it more go with a slightly stiff spring and adjustable with remote canister. Call jri and dse. They are helpful.

Also where are you located?

Well it already has the 450 and 250 in the rear. I called DSE today and they recommended the single adjustable JRI’s that they are putting on there frames now. I am in located in McKinney

the 450's they were sending with subframes was too soft out of the box. hence the reason you have a blown shock. 550 is plenty and will give a good ride, 250 in the rear is fine as well.

I run 650lbs/in front
And 425lb/in rear

It's a 68 Camaro with a 572BBC so it's nose heavy.
My second set of springs and now springs are perfect for spirited driving!
I autocross the car but don't get crazy
I lean on it pretty hard on the street

I prefer lighter spring rates and heavier sway bar rates on the street. But I am an old man...
