It came up recently in another post, so I'll throw this out there. I was considering the Kosman rim widening, but after paying$ 1000-$ 1500 for a custom rim, and another$ 1000 to have it widened, ground, and rechromed, it didn't seem that affordable. I contacted most of the custom wheel manufacturers to see if anyone made a rear rim in the 18x7 size. The universal answer was that no one produces a wheel blank in that size and that it wasn't possible. The only one that showed any interest was RC Components. I had several emails with their director of marketing and their R&D department. They stated that they would conduct some market research into making the new size. They also stated that the initial start up cost to produce a new wheel size is extremely high, possibly up to $ 100, 000. They explained that the dies, tooling, and machinery required would be around $ 35, 000 and the blank manufacturer would require then to order a MINIMUM of 100 blanks. My thought is this. If we can show them that there is sufficient interest, maybe they will seriously check into having the blanks produced. The cost would not be cheap, but it would be less than the Kosman widening, and definitely cheaper than the Sumo-x. And it would take some time for development and production, but that would give us some time to save up the money... Lol. I think that if we flood them with emails of interest, we could get this done! Let's band together Fury Nation and we can all get wider rear tires and custom wheels! If you do email them, post it on here so we can keep count for ourselves as well.
