Jeg's site is awful. I don't even go there without part numbers. That's my only complaint about them and I appreciate that the whole family races. Summit's website is much easier to use and stuff seems to get to me a day earlier for some reason. On the down side for Summit, they not only sell Chinese knockoff stuff, but they are pretty active in having stuff reverse engineered there and selling it under their own brand names. Makes for bad feelings with their vendors whom are being ripped.
