searching is your friend( althought the search engine has been a douche bag recently), and yellows are not neccesarily the best out there, many ppl prefer Illuminas...i have shortened and revalved Illuminas as part of my Illumina R coilovers, and love em
Not that I've found. I just finished researching shocks for my suspension and Koni yellows were the best for me. You might be able to use kyb depending on the spring rate of the H&R sport springs. Kyb is cheaper than koni. Also consider tokico illumina. If I wasn't going to run such an agressive rate I'd have gone with the illumina.
