Shock Diameter for Coilovers

i'm having to purchase replacement lower mounts for kSport Kontrol Pros, is anyone aware of the shock diameter i need to be purchasing?

they give me the options 42, 50, and 52mm. after using the "identify my coilover" link, seems like its either 50 or 52mm.

PS: sorry for the double post, i realized that this would be the best place to post it w/ mines being an 8G

K sports fucking suck. EVERYBODY blows their shocks, absolute garbage.

They've put different diameter shocks into different production runs. You'll have to get a caliper and measure the shaft diameter yourself.
