Default What suspension w/ DSE Sub frame?

I have a DSE sub from 2010 and I believe the springs are 450 or so front and 250 rear. My front shock is blown and I am debating getting all new shocks due to age of the current shocks. Shop I am going to recommended going with a custom valved JRI (not the ones straight from DSE) as well as going up to around 800lb spring up front and 450 in rear. He said I could go with single adjustable that would be around 2500 or dual for 5k. To me that sounds a little overkill.

For those of you that use your car for track and everyday driving what are you running?

I should add that this is for an SBC and it has the full DSE bells and whistles front to back

In the coming months I plan to add an oil cooler and use it on both track and as a daily driver. However, I beat on it pretty good while daily driving it

Ride will be quite harsh on the street with those spring rates imho. Especially the rear....

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.

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

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.
