Ok, so Amuse has changed the entire rear subframe to "2004 spec" recently. I did some investigating and the AP1 and AP2 rear subframes are different part numbers (front subframes have the same part numbers). I also found that the rear lower control arms and radius (toe) rods also have the same part number. However, the AP2 rear upper control arms are different. What I want to know is if the rear upper control arm was the only geometry change they made to make the toe curve less aggressive, or did they change the attatchment points on the subframe as well?


As far as the front, it seems the only change is a revision of the front lower control arms.

Part numbers:

AP1:
Front LCA: 51350-S2A-000 (Right)
Front LCA: 51360-S2A-000 (Left)

Rear UCA: 52390-S2A-003 (Right)
Rear UCA: 52400-S2A-003 (Left)

AP2:
Front LCA: 51350-S2A-030 (Right)
Front LCA: 51360-S2A-030 (Left)

Rear UCA: 52390-S2A-000 (Right)
Rear UCA: 52400-S2A-000 (Left)

And I was curious about AP1 sway bars, this is probably out there already:

Early AP1 ('00-'01):
F: 28.2x5.0mm
R: 27.2x5.3mm

Late AP1 ('02-'03):
F: 26.5x4.5mm
R: 27.2x4.5mm

As you can see, the front was made a smaller diameter and thinner, while the rear only changed slightly in thickness.
