Cool, that would be helpful! I only want the Yellows since I've read so many positive things about them. My car is also a DD that I like to drag race occasionally but I'd also like it to handle well too (been thinking about going to Barber some).
For me it's not just being able to make them soft or firm, it's being able to fine tune them exactly to the spring to get the best ride and damping, which is what I was after. I have had the koni yellow's on my Taurus SHO for almost 10 years and they have been great! Still working awesome too!
