Does anyone here run TRC tires with your Quad12? If so, how many shims does it take to get your rear tires to 6.75"? I have the IRS rear pod plates and the IRS axle. I have the hub reversed on the left side which moves the tire out enough to clear the lower pod. At this point I am still adding 2-3 associated shims to the left side and 15-16 shims on the right side. This centers the axle perfectly (measured at the notch on the lower pod) and the tires are just under 6.75". Is it normal to need that many shims? If so, any ideas where to buy thicker shims? One shim that is .1" would be just about perfect.
Thanks
