Most of us tracking these cars do everything we can to minimize or eliminate KT. flat solid sides are fine and have no impact in this area, they do move the subframe up into the chassis, which on a lowered car restores the geometry, think of it like the RS wheel carriers and tierods used in front which restore geometry on lowered cars,..
Lowering the front of the subframe reduces anti-squat. I remember reading that a stock 993 is ~90%, I think a more typical target is ~50%. Could be that the A/S was reduced to compensate for super stiff GT2 springs to improve traction or make the cars easier to drive?

what kit did you buy, Rennline, ERP and FVD all have 2 different versions of sub-frame kits, one tilts and one is flat. You want the flat version. From what I have seen the Rennline kit is the best and most complete.

How much does the subframe move up relative the chassis?

The tilt kit is for anti squat, however it is to compensate for the HP and Torque of the GT2 motor.
The rennline kit can be installed as either the tilt or solid (no tilt kit)
