I got a set of 6 speed engine and gearbox mounts from Bren@Apexi through the group buy, I got the geartbox mounts fitted relatively easily. But when I undid the engine mount to subframe nuts and remopved the pitch rod. I tried to lift the engine, the whole car moved. I then loosened the gearbox mounts and tried again same thing. What am I missing or are the mounts stuck to the sbubframe with age?

Thanks Steve
