H and r just throwing some random ass spring rates at your car. I have no confidence that they have done any research into the spring rates for the m3/4.
Whatever floats your boat I guess. I just can't believe someone would install that on their car.

That way they can be the first to lower their M3/4 on the block!
The difference in rates are a given. The M3/4 rates are likely higher. In the E9x chassis the rates are 10% higher in the front and 20% higher in the rear.
It does seem early for H&R to come to market with sport springs when the M3/4 just barely released. It will be interesting to compare the OE vs H&R rates.
