Lowering the SRT does indeed affect the handling. I honestly think that lowering the car has adverse affects in this particular setup. I talked to Brandon at Code3Performance and he had a really good idea that he turned into a product (unfortunately not for the R170 chassis).

From the factory the sway bars are on the same horizontal plane as the chassis (or unibody in our case). When you lower the car the sway bars are no longer parallel with the chassis. This situation greatly reduces the effectiveness of the sway bars. Brandon fabbed up some adjustable sway bar links for the W203 chassis which had an entirely different mounting method. Ours have a stamped steel type of bracket not to mention an air conditioning line in the way. With some time spent I'm sure something could be made to alleviate this problem.

I don't track the car, it's my daily driver. The ride does firm up quite a bit more (I didn't think that was possible) and you can't deny the much better look when it is lowered.
