Could be the GP Sports version alters the geometry in some other way? No idea...

It totally could…maybe the new trailing arm mounting location is closer or further away relative to old mounting location causing the sag.

To be honest I did forget to tighten with load on the suspension so this is a very interesting point. I’ll go back under soon and see if I can loosen/re-tighten with the appropriate load.

How are you liking that spring rate? I imagine it’s similar to the oem STi springs which would mean we have another oem+ option on our hands. Did you notice a drop at all when you did your Traction mod?

I wonder if tightening an OEM trailing arm with the rubber bushings at both ends while at full droop for install changes things enough (binds up) to impact ride height that much. Not sure.

Man this was what I was afraid of lol. But my non-educated theory would be that if I tightened the bushing’s bolt with the suspension at full droop, that the associated pre-load would actually raise the car? I have 1/4” risers getting here on Monday but I’m going to try and re-do the subject bolts before I dismantle my alignment to install the risers.
