According to Ohlins, there's a bespoke 1M kit available now. It differs from the M3 kit in that the rear spring rate is 110 N/mm (628 lbs) instead of 120 N/mm (685 lbs). This is presumably to compensate for a lighter car.

For those of you who have installed the M3 kit, do you think that this decreased spring rate would make a substantive difference? I'm trying to get a sense of how important this would be for overall feel and driveability. (I figure the wizards at Ohlins know what's going on.) Incidentally, this would be for a combined road and 5-6 HPDEs/year scenario.
We have found the 1M likes the 12kg springs, both on and off the track, although 11kg is not really that far off. You are not really given up much with the lower spring rates and may pick up a bit more comfort for the street from the already very smooth riding coilover kit.
