I am not really looking for the lowest but best handling coilovers. I plan to do a full suspension system and have been told that if you run with one company for all the parts, Strut bar, Sway bars, Frame brace, Coliovers. Is that true or not really a big factor?

I have been looking at the following

Blitz
Tanabe
Cusco
Ksport / D2


I would like to hear from guys that have used or are using them. Any info would be awsome, Thanks in advanced.
