Best source for 2.25 rear springs in USA

[Tahoe]

This is really a 2 part question. First who do you think is the best source for these springs, and second, what is the best free length to get for the best adjustability? I already have everything else in place except the correct springs.

My brother was a champ car engineer, he used hyperco because they held their spring rate and free length best.

Thanks for the source. I just noticed RD has 12 inch springs in 90, 100, and 110. So, has anyone here used those springs and was the ride height acceptable with plenty of adjustability? I have 2 sets of Koni fronts and need to determine those rates and come up with a rate for the rear. I'm hoping for a good road set up, nothing too stiff.

I'm very interested in this information too. Also any US sources for the weld on threaded sleeves and perches for the rear struts? John

As with the above. Hyperco are the only springs to consider.

Hyperco does look good. I guess my only real question is the free length. Spring rate is on me, but I don't want to screw up the length. I assume that the 12 inches RDentry supplies must be a good length, as
I've heard nothing negative to date.
