[koullis]

hi guys, the thing i want to ask is: is the jdm s15 spec-s sr20de r180 or r200. please answer only if you are sure.

i am asking because i bought a used helical lsd from an s15 spec-r and now i am not sure if it will fit my car. the guy said that is r180 but i don't know for sure. i still haven't got the item, just pics.

You can tell if it is a R180 or R200 by the size of the ring wheel, if this dimension is 18cm it is a R180, if it is 20cm, it is a R200.
