Someone posted something a while back saying that he found that the front shocks from a 350Z fit the SC with very minor modifications to the lower clevis of the shock. I think he had to open up the mounting hole and spread the clevis very slightly. The top supposedly bolts right up. It doesn't accomodate the ARC, but if true, it should open the door to a whole lot of performance options. I have no doubt the 350Z would have much more aftermarket support.
I just received a pair of OEM SC front shocks to complete a full set of 4. I plan to experiment with making them rebuildable. It'll be a while before I can get to it, but it's gonna be an interesting project. I'm going to try to make the best of all the connections I made in my racing career to make it happen. We'll see how it goes.
