I don't mean to hijack the thread, but I have a related question. I bought a WD C4 Sub from Andy Hoffman and it came with single adjustable QA-1's. The springs on it are only 300's. That seems awful soft to me compared to what DSE uses on their sub and what everyone is recommending for the C5 frames.

What do you guys think?

My Art Morrison max-G frame has the C-5 front suspension. I went with double adjustable Strange shocks front and rear. The rear suspension is a 4 link/watts. Just finished. My starter springs are 500# front and 150# rear. This is a 70 A-body, and should be in the neighborhood of 3300#. As soon as its possible, Ill post some pics.

Rob, I can understand wanting to match the rears, brand wise...I felt the same way and bought QA1 for the front as that's what I started with on the rear a couple years prior.

I'm sarting with:
550# front DSE recommended 575# but QA1 didn't offer them at that time.
200# rear

Hey Tony, I was talking with Frank Serafine the other day and he managed to work a deal for me on a set of Strange D/A coliovers (same as what ships with the AM sub) w/550 lb springs as a starting point...should have them soon. Thanks to all for your input, -Rob
