Yes. I heard this before and agree to it (I never tried it before, so...). I think the links should be shorter because sway bar is attached to your lower portion of your car. If your car is lowered, sway bar links should be shorter, I think. (I'm not a professional car mechanic. Please verify it by yourself.)
In addition, stiffer sway bar is not always better. Too stiff will lose grip(especially in rainy day and happen in the rear) and it will become very dangerous.
Also every time you drive a new car or new setup in your old car, DO NOT drive fast suddenly. You need to drive it from slow to faster to understand its limit little by litte. Safe is the most important!!! Good luck.
P.S. Sorry. Please use Google Translate if English is difficult for you. Thanks.
Sorry. It could be shorter or longer(my G35S is longer but my GSF is shorter). It depends on your car design. You really need to verify by yourself. But swaybar should be attached to the bottom of your car. If your car is lower, the whole swaybar should also be lower(closer to the ground).
