Installed D2 RS coilovers this week and I absolutely love them. 36 way dampening and the rear spring mounted on the strut so no more independent spring and strut. No noises what so ever and the quality of the coils is top notch. I'd highly recommend to anyone looking for coils under 1k. Only downfall was the rear coils didn't have the nut welded to the bottom perch so you need to find a nut that fits the stock bolt or just get a new bolt/nut setup. These are perfect for anyone looking to go really really low. R2 claims you can drop 3.5" but I think you can go even lower with our sedans if that's what you like. The spring rates are 12.5 up front and 10.5 in the rear but you can get custom rates if desired. I'll post some pics of the drop in the daylight this weekend. I'm currently at 25 3/16 in the rear and 25 3/4 up front. I told JM Auto Racing I'd give them a shout out for the great customer service so hit them up if you're interested.
