I have been talking to an Asian manufacturer of one piece forged aluminum wheels and the possibility of a Fiesta specific wheel is there. It would be a 10 spoke design, 17*7.5 or 8", lighter than the OZ wheels that Mountune sells with close to similar pricing. Speaking of OZ, their 9 spoke Alleggerita HLT in 17*7.5 45mm et weighs 6.2 kg and is made of cast 356 aluminum. The wheels I'm looking at may weigh as little as 5.5 kg and are forged from a much better material. If there is potential for a small group buy we can change details like rim offset. In any discussion of wheels, tires should be addressed. The Dunlop Direzza Z2 215-40r17 seems like the best available near stock size. I think a 16" wheel and tire combo might be optimum for the ST but the tire choices don't seem to be there. 15" might be great but does not leave any room for bigger brakes which I really would like. 17s have a few good tires, rim weights are higher than I would like but they will work. For a set of four rims with tire pressure sensors and tires, I estimate around $2,500. I have no idea on delivery schedule. If anyone thinks that is something they have interest in, let me know and I'll give you the details when I get them. I know it's an expensive way to lose ~36 lbs but for people who race or just want the best, it may be worth it.
