no, the calmini kit didn't come with the extension because I bought the optional Calmini track bar. However, measurement from eye to eye of the calmini bar is the same as the stock track bar - 37.5". I asked them about it and they said it was supposed to be 37.5", but when I asked them about why they use an extension for the stock ones, he said that because the bar was bent, that it didn't need to be longer - it doesn't make sense to me because the only thing that matters is the distance from eye to eye. THe bend just helps in clearance. I did talk them into overnighting me the track bar extension and 2 new UCA's since the screwed up the ball joint bolt pattern on the first set. I hope they let me keep both sets of UCA's since the first set will just take some milling to get them to fit, then I could sell the 2nd set to make up for some of the expenses that Calmini has cost me by shipping me bad parts.

Anyways, I am thinking about extending the track bar by 1/2" by cutting it and welding a sleeve over the bars. How much force do these bars take? In other words, how beefy will that sleeve and welds need to be? I am guessing that the majority of the forces that this bar sees are compression/tension forces.
