Because of the upper spring seat is larger in diameter than the lower spring seat the rear coil has a progressive design.
In all of our track experience with the 5th Gen we have found that matching front and rear coil rates deliver the best handling. Our L/28 is running 12kg coils front and rear. Our lowering coils are not that aggressive to preserve ride quality. I have been considering a change to our lowering coil spring rates, but haven't pulled the trigger. There should be an OE upgrade around the corner with Z/28 coils.
The 1LE difference makers are foundational bushes and a rear bar upgrade. Normally we would do foundational bushes, lowering coils and then bars, but the 1LE responds exceptionally well to bushes and rear bar. We have a number of 1LEs on lowering coils along with ZL1s with very satisfied owners. I believe the 32mm rear bar with the OE 27mm front delivers a greater performance increase than lowering coils.
