STI lateral links on GC/GM

    I posted this up on rs25.com as well, but here it goes. So people have claimed that running the STI lateral links pushes out the GC/GM geometry out 10mm out each side. Well I currently mounted up the GD rear subframe along with some whiteline adjustable lateral links and saw no difference in the geometry changes.

    Now before you say that I didn't adjust it right. I took the OEM STI lateral links and put them side by side with the whiteline's and adjusted the whitelines so that I could start off at OEM STI length.

    This is where it makes no sense to me. I was running a 20mm spacer in the rear to fill up the gap in my flares. Now with the GD subframe and the whiteline lateral links in place, I figure it would push out my rear by 10mm, so I would only have to run a 10mm spacer. WRONG. I got a 10mm spacer and mounted it to the car and then put on my wheels.....the wheels are sunken in. I then put a 20mm spacer in and it was back to how it was when I was running the stock lateral links.

    I either have the lateral links setup wrong, or the myth has been busted. I mean I could always just adjust the links to extend, but wouldn't that mess up the geometry of the car?

    GC and GG(02-07 wagon) are the same length
    GD 02-07 WRX and 04 USDM STI are 10+
    GD 05-07 STI are 15+

    Do you have adjustable rear camber plates?

    If those STI links are what you had previously then you were setup with the longest OEM links hence...

    Yea this rear subframe I bought was from a 05 STI. So technically it should be a big difference. No I don't have adjustable rear camber plates.

    So for the fronts I just bought the bottom piece collar for my coilovers to fit the new 5x114 hubs, but the rears bolt right in. The only thing I can think of is a combo of the tophat mounting point and lateral links of the GD are setup different so that's why I don't see it when I mount it to my car.

    compare the STI links to the RS links is the next logical step
