The AST 5100 Street coilover set for 1996–2001 Lotus Elise S1 is a monotube, non‑inverted suspension with 1‑way adjustment for rebound and ride height. Front dampers use a coilover design while the rear retains an OEM‑style divorced setup with fixed spring rates. The package includes springs sized for OEM top mounts and rebuildable dampers to maintain consistent handling on the road.
