Okay, the purpose of this is to be a reference for those looking to get some nice lightweight rims that hopefully won't break the bank, so I'll just outline a few rims/tires that I know about and others can add and hopefully we'll have a decent list.
Wheels:
4x100
Miata Panasports (I think they're called)
Weight: 12 pounds
Size: 14"
Notes: Need to be bored or used with a spacer to fit most Honda hubs
Price: 100-300$
Honda Civic VX Alloys
Weight: 8.5 pounds
Size: 13"
Notes: Won't fit a lot of larger brakes
Price: 100-150
Honda Civic HX Alloys
Weight: 11.75 pounds
Size: 14"
Notes: Ugly, 24.4 pounds total with Potenza RE 92 (165/65/14) LRR Insight Tyres
Price: 200-300
Tires:
Michelin Energy series and Harmony series are recognized as being LRR. They replace some of the carbon black with silica.
The Bridgestone Potenza RE 92 in the 165/65/14 size has 40% lower rolling resistance than a non LRR tire. This is the size used on the Insight and as I understand it, all other sizes of the Potenza's are not LRR. - Dan
