I have BC BR type coilovers in my SW20 MR2 and am quite happy with their performance. The car sees at least 6 track days a year, and I find them easy to adjust from the soft road setting, to harder track settings. There is a BIG difference between the settings!
I was looking at some BC coilovers for my 260Z 2+2, but am getting confused/concerned about original widths and lengths of the OEM setup. Apparently the later Zeds, (mine's a 1977) have larger diameter
springs and shocks? I don't want to buy the wrong thing.
Also I've bought wheels, (15x9" 0 offset) that are too wide and foul on the spring perches, so I'm looking for a bit more clearance which is why a coilover setup will make more sense.
