Vorschlag/AST/Moton Hands On BRZ

It sounds like you're assuming the spring perch shown is consuming usable damper stroke. It may or may not be. We'll have to wait and see the actual parts from AST, though I'd be surprised to see them leave usable stroke on the table when it appears the setup is already a bit light on stroke.

Yes, that is my assumption because the piece looks to be similar in dimension to the Subaru WRX 4100 perch which is designed to work with the oddly shaped factory spring perch. From my understanding it put the bump/droop travel in the right position for use with the factory mount in that application. The spring perch on the BRZ does look to be a different design, so the same may not apply. However, I think the bump stop should be able to move further up the shaft before beginning to compress. We won't know for sure until it's tested, but if it is unusable stroke, I think there is still more room to extend the bottom portion.

I just want to add to this thread that I had AST 4100s on my 02 WRX. The damper tuning that Vorshlag did to these was incredible. You are still largely at the mercy of higher spring rates (depending on what you get), but the damping could not have been better tuned.

Anyone who wants higher spring rates on this car would do really well to choose AST dampers (blatant plug).
