"Pre-gen"s don't cover just 1 wheel type. Obviously you haven't done research on the subject, but its ok, I'll enlighten you.
Commonly we refer to pre-gens among the 92-96 wheels due to them being rarer than the others. As I posted, again, you didn't research nor did you read. "...and there were several wheels offered at the time. 3 being 5 spokes, 2 being twisted so then you have to specify the honeycomb or the straight thin 5 spoke wheels..." Now, that being said, allow me to explain, Lucy.
Crosslaced wheels appeared from 88-2000 but the difference is 1) 97-00 they twisted them, 2) the 97-00 backspacing is rediculously high (aka, they're sucked in more than previous years), 3) color options, 4) 97-00 wheels were thinner, 16x8 down to 16*6.5.
The 5 spoke wheels are similar to the untrained eyes, these are the ones that go from 94-96, but 97+ got wider spokes, again with higher backspacing, lost the really cool PONTIAC engraving, and as with the other got thinner. Most people want one of these 2 as the backspacing is lower so it sits more flush with the fender and gives a more aggressive look and can run a wider tire.
The other 3 wheels options are pointless as nobody really goes for them because, well, they're hideous. But in that regards, rather than trying to explain which year model wheels you want and which variety we simply dub pregen and let it go. just as you should with this arguement.
Should you feel the need to pursue said arguement, The Rant Forum - Make your own thread.
