[QUOTE="greg brillus, post: 64726, member: 597"] It is quite possible looking at Patrick's bike above, he has from what I can see, one of the Thornton shock's on the front, which has been threaded and a coil fitted, or else he has just installed one of the coil overs readily available for the rear, and fitted it to the front. I would say that the spring loading will be way too high. I had some springs made to suit my coil over, and opted for one rated at 180 to 190 lb.'s which as we all know, is the same loading as that of the Brampton's.
