We use the S550 front hubs on the S197 which allows more stud options rather than the direct fit ARP's. Several Customers have converted the front to 14mm for extra capacity especially with some of the 11+" wheels and tires getting stuffed up front. We have a mid-length 14mm stud that safely takes a 15mm spacer basically splits the 1/2" and 1" longer than stock S550 ARP stud.
