Rear coilovers & Procomp shock mounts at BurleyMS

I was chatting with Burley and told me about these coilover mounts he is starting to produce. Might just be the hot ticket for those like me who have a relatively lightweight Doka. The only springs I can find presently are all designed for Westies and vans. Took my Syncro (14) Doka to the scales last week and it only tipped the scales at 3440 lbs sans skidplate. I don't think it is smart to put my GoWesty springs or even Syncro.org springs on by truck.
I don't care muchfor the arches springs but Burley says it flattens out when the suspension is not at full extension. The pic in his webpage was apparently taken when the suspension was in full droop.
Thoughts?
