I have 18 inch storms, they weigh in at 17lbs. very light, just as light or lighter than any stock wheel. As for being rare, all you have to do is call centerline and open your wallet. anything can be obtained with enough $100 bills, welcome to the United States. The storms are tough as hell too, I hit a huge pot hole int he rain, never saw it, messed up my wheel bearing, not my rim.
Also the reason why they dont look as aggressive is because they where actually made to fit the 97-03 grand prixs! they care 5X115mm spacing and have a 42mm offset.
Heres a pic of mine, im still playing with the height as im currently installing coil overs.
My advice is keep the pre gens and run slicks on them for the track and storms to look nice, If not I do need a set of wheels that will clear 13 inch brakes that I can put some DR on.... lmao
