The RS-R will probably be in the suggested .9:1 range (I calculated 1:1 with my preliminary estimates) but the HKS will be in the range of 1.34:1 which can cause some uncomfortable pitch oscillations over bumps. Their numbers actually look like they would be better reversed. A little bit confusing.
Lower frequencies in the rear can actually be done for more comfort or other reasons...its not necessarily the end of the world. The springs are not the only things that control the balance if the car. However, spring rates that are much much lower in the rear are not imo a good idea at all on this car. Sometimes companies do things without a good explanation.

The rates you posted might be very aggressive imo and probably a bit of a handful on a track without a big wing.

The RSR rates posted are pretty good, kudos to them. I agree that rates along those lines would be a good starting point for autox depending on other factors. An upgraded rear bar should be matched with a front if you want/need additional roll stiffness or want a quick easy way to adjust balance with those rates imo.

Cool to see what looks like a quality product coming for this car!
