You are 100% correct rabbitron!
I did not think that further explanation was needed since I was talking about oversteer. Oversteer only comes to play during cornering.
Thank you for bringing it up kenchan. It definitely deserved to be explained in detail. My bad!
Progress is the choice to go with if you are not going to AutoX, Road race or take canyons like devil himself was chasing you. LOL! It will give you greatest cruising comfort with least bouncy ride as long as you are not carrying lot of cargo weight and/or 2-3 rear passengers. In that case pick a brand with higher rear spring ratio.
Here is the spreadsheet sorted by "front to rear stiffness ratio".
I find it easier to start from there for the sake of balance and then compare spring stiffness among manufacturers.
One thing I find amusing is that both Eibach and H&R refused to disclose spring rates considering both Eibach Pro Kit and H&R Sport Kit have identical drop! ROFL! Is it being manufactured in the same facility?!
Email me if you would like me to send you the spreadsheet.

p.s. I wonder if picking softest front spring, stiffest rear spring and addition of Progress rear sway bar would make an impact on the drift competition? LOL! Just kidding!
