yah i talked to him at a rallyx, he wouldnt tell me anything useful. i got the feeling he knew a lot less than he seemed to think he did. for one thing, he claimed he personally revalves sealed bilstein, without using a shraeder valve... riiight.
i'm guessing the struts he uses are 50mm OD.
i dunno how much stroke you need, but I'm using 36mm 3000gt inserts up front in my car. they have ~4" travel to the internal bumpstop, but its pretty long (a lot of guys cut it in half or whatever).
