I'm running the Meister R GT1's. I didnt need anything extra to get the roll center correct. They also have enough adjustment to pretty much go as high, or as low as you want (within reason of course). Linear springs, dyno tested, camber plates, what else could you want. The lead time sucks tho, but that's going to be with any custom coilover setup. I would like to try the 510's sometime in the future and get a good comparison. I looked at the BC's, but went with the Mesiter R's because they actually have a little bit more suspension travel. Hopefully this helps you out a little bit.
