We use Enkei Race Series wheels on all our R&D cars with Aircraft Lug Nuts for the absolute minimal weight within the wheel (Pictures in listings). Enkei Race Series 19x8" wheels weight about 19-22lbs depending on which type, Aircraft Lug Nuts save an additional 2-3lbs per wheel.
While we understand the average person cannot afford Enkei Race Series Wheels, Enkei Tuning Series is not far behind in terms of performance, weight and durability. If you cannot afford Enkei Racing, look at Enkei Tuning Series!
Sparco OZ Racing Wheels which we sell are the best bang for your buck, so good we have customers buying them for winter use. We ourselves use them for winter use.
