Outside of style what makes them superior to the Motegi? (sorry not being a d!ck I am just somewhat of a newb).

Kosei is well known for being a high quality wheel manufacturer like Enkei Racing series whose wheels are made in Japan - great price for well engineered and reliable wheels that are lightweight. The K4R's are a brand new wheel from Kosei, but for $200 you get a 15.6lb 17x8 wheel with 36mm offset, and it comes with lightweight machined aluminum valve stems, center caps, and lug nuts. 35mm-36mm offset is the perfect offset for an 8" wheel on the FR-S, yet so many 17x8 wheels only come in 45-42mm offset (cough...Enkei...)? So it's one of the few 17x8 wheels with a 35-36mm offset.
If you compare the Kosei K4R to the Motegi MR125 you can see the extra care Kosei took in engineering their wheel versus Motegi to handle track loading better (root blending and spoke geometry)... the Motegi MR125 would probably be 'ok' to track, but I'd much rather go with the better designed wheel. Motegi did make an excellent forged lightweight track wheel known as the Traklite, but it doesn't come in any sizes (- offsets or huge + offsets) that really fit the FR-S any more.
Not sure on the Motegi MR125, but with the Kosei K4R's there is a ridiculous amount of clearance if you want to upgrade your brakes to the AP Racing Essex Sprint kit:
