Put a few miles on since changing over springs/pistons, so wanted to update this thread in case anyone following.

The end configuration is - as is - apart from B1 piston, for whatever reason little (read 'no') information exists about this particular 'bottle shaped' upgrade so difficult to match against.

The longer spring didn't perform as expected, so took a gamble putting back original double without the inner smaller spring.

This gives a super soft change under normal throttle but still a noticeable delayed lurch under hard acceleration, some of this may however be expected with such a heavy car.

Cheers for now,
