I don't have them on my LS yet. The North America LEDA distributor is here in Knoxville, TN so any orders for LEDA go through the company here in town. He is at my back door and I have spoken with the rep several times. He told me last month that lead times on the LEDA's are about eight weeks. They are made in the UK and are made per order. The cost is around $400 a shock. So, you're looking at an easy $1,600. I just haven't broke down and bought a set yet. However, they are fully adjustable as advertised.
