Most sites, including manufacturing sites, don't have the specs. Calling everyone to get backspacing/offset, weight etc is a major pain.

 

Try writing a manufacture for how much their wheels weigh. I didn't have one vendor write me back... prolly 'cuz thier wheels wiegh a ton and have crappy construction. The only vendors that ponied up that info are the forged wheels, they are strong, light and uber expensive. You get what you pay for. If they don't advertise the specs, there is a problem!

 

Weld does not, and they are light, one piece forged, qulaity wheels. They'll give you weight on the phone though. Same with American Racing, Mickety Thompson etc
