I have straightened rim lips using a block of aluminum and hammer. First grind the block to conform to the lip on a good part of the rim. Try to stay off the edge and take it slow. I'd say you could help it quite a lot without dismounting the tire. After staightening stick it on the car and spin it and eyeball for runout. You can spin a good one to get a comparison. I would use it only on the rear.
What is the weight of one of these wheels. I have heard 5-7 lbs.
The weight of the VX rims were 9.75 lbs IIRC. And congrats on finally getting a set of VX rims, UfoTofU!
Safest, but not the cheapest, way to straighten out that rims would be to bring it to a tire shop that deals with that sort of thing. I can't look at the full size pics at work so I don't know exactly how bad it is. But it could be pounded out gently using the above described method as well.
I would be extreamly warry of "fixing" an alloy rim, as aluminum will crack if you bend it to many times, so if the dent is not causing you problems, leave it alone or you might just brake a chunk off.
Decided to go ahead and replace the bent rim with a new used one. My brother again helped me track down another pair and went and picked them up for me. No pics yet but I do have a couple of the set so far including the bent rim (#3 see pics below).
Rims are in excellent shape. I dunno what I am going to do about the color though. I think that I want to paint them black.
