Your right skyline, lighter is not always better. My use would be street primarily with an autocross or maybe a rare track day every blue moon. But I really just want a better looking rim than stock to slap some summer rubber on. The lightweight stockers make it a challange to keep weight at or below oem. Not to mention light gets real pricey real quickly.
Notice any acceleration difference with those 18's? Think I'm in the market for 17's.
