Chevrolet hasn't changed its mind in that regard, but has announced it's to offer a series of Z/28 performance packages so Camaro buyers can at least bring their cars a little closer to the performance flagship. Notably, some of the Z/28's styling touches are still off-limits--but nine other packages will be available.
According to Car And Driver, packages include a suspension kit with spool-valve dampers, springs, anti-roll bars and other parts; a helical differential with heat exchanger is part of another kit, and various cooling, induction and exhaust parts are also available in pre-packaged kits. Recaro sports seats are also on the menu, while some aerodynamic components--wheel lip extensions, splitters, an underbody tray--will give some of the Z/28's feel without replicating it exactly and spoiling that car's exclusive nature.
For those really wanting Z/28 performance but not keen on the Z/28's $75K sticker price, you can even buy its 7.0-liter LS7 supercharged V-8--available as a crate motor (for around $16K) for anyone who wants it. Any customer adding all of these packages would probably be better served buying a Z/28 in the first place (though supply of the car is limited) but for one or two packages alone, buyers could enjoy quite a useful upgrade over their standard Camaro. Shy away from the more visual cues, and you'd also have quite the sleeper...
