Steve Payne. Emailed him a while back and got no answer. Not sure what's up with him or if he ever made any kits from the Hyper molds as was the plan. Captain Jaguar's Cathouse still sells the original 1st generation Lister body kit for $1600 (excluding the Lister rear spoiler which is another $330) here: Jaguar ground effects
It's similar to the Hyper Stage I kit, which bolts under your bumpers but does not cover the tops—the chrome blades are left exposed.
The picture I posted earlier of the red car had the Stage 2 Hyper Transformations kit, which replaces your front and rear bumpers completely with fiberglass units which I believe are filled with foam.
I shudder to think what shipping would be for a Hyper kit from the UK. Plus, if I was willing to pay for shipping from that side of the pond, I prefer the 1st generation Arden kit for the XJ-S.
