Top mounts in the pics are Compbrake, however had to go back temporarily to standard over the winter as the bearings in them failed and punched through the camber plate. Seems like a relatively common occurrence with these top mounts.
Ordered a rear cage from Single Source Motorsport and installed this weekend. Nice bit of kit, fitted well and finished well. When it's warmer and less windy I'll weld the footplates in properly, for now just bolted through:
Car's not doing too many miles at mo (lockdown/WFH) so easy to keep clean. Need to do something about for a front splitter next.
