S14 subframe & knuckle in S13: what R coilover?

[adey]

Hi everyone, I'm sure this has been covered before but I can't find the thread. (I tried multiple searches...)

- My car is a 1998 RPS13 with HICAS.
- I have an R33 GTS non-HICAS (which IIRC = S14/S15) subframe that is waiting to go in.
- I have GKTech V2 rear knuckles (and all their arms) on the way. (https://au.gktech.com/v2-s-r-z32-cha...new-kinematics)
- **I have coilovers on order, but pending confirmation of which lower mounts to use**
- (Of course, I also have an S14 diff cover waiting to come in.)

So, my question: What rear coilover combination should I use for my car?

My understanding from reading other posts is that if I were to use the OEM S14/S15 knuckle, I would need the S14/S15 rear lower coilover mount. However, in this case, GKTech rear knuckles are universal. So should I use the S13 rear lower mount??

(S14/15 rear coilovers are almost 11cm longer than S13 versions, and most of that extra length comes from the lower mount)

Thanks in advance!!
