Suspension upgrades [Coilovers & Top mounts] April 14, 2017April 14, 2017 admin Discovered recently that one of the front springs had snapped, so seemed like a good opportunity to upgrade the suspension. The choice was narrowed to Bilstein B14 and Compbrake top mounts, or AST 5100 series. Ended up going for the Bilstein option as I felt it better suited the dual purpose nature of the car. AST I think would have been a bit too track orientated and specifying them with softer road biased spring rates made the extra expense seem unnecessary. I also wasn’t sure adjustable dampers were what i was after either, when doing track days I generally prefer to just turn up and maximise my driving time, rather than messing about with setup. Whilst I had it all apart I took the opportunity to also replace both wishbones, anti-rotation links and have the radiator cross member powder coated.
