My TT is a 180 FWD, will the Kmac kit work for me if I lower it?

Here's your answer (iow, this is what the KMAC kit does and why FWD TTs don't need it) -UPDATED-
The rear suspension in quattro TTs is independent. The mounting position of its suspension arms alter the geometric angle of the wheel relative to the ground as the suspension loads and unloads. When the car is lowered, it results in a wheel angle similar to that of being loaded.
Below is the quattro rear suspension. I've circled the area on the two arms where the KMAC bushings go (they simply replace the OEM ones). The arrows show the direction that these adjustable bushings push or pull the control arms. This results in pulling in the bottom of the wheel and pushing out the top--both ever so slightly.

Here's my quattro:

Front-wheel drive TTs do not have a fully independent rear suspension, but rather a bar that connects both right & left wheels (oversimplified explanation, I know). When you lower the car (bringing the bar closer to the body), it does not change the wheel's geometry relative to the ground. Accordingly, you do not need to correct the camber--it is unaffected by lowering.
Here is TTowsonTT's TT for example (FWD):

Got it?

Great explanation of the differences - all I'll add is that both cars have
right and left trailing arms which the wheel hubs are connected to. The Quattro's are fully independent while the FWD's are connected with a torsion bar with integrated sway bar. The rear camber is not adjustable because the trailing arms are attached to the torsion bar.
