Question? So I now have modified, and assembled the Wilwood, 12.19 T bird irs brake system as per instructions. This is the 4 piston type with the 12.19" rotor, and drum type emergency/parking brake. It was originally designed for a solid rear axle, but comes with retrofit pieces to make it work on the IRS T-Bird type of knuckles. The issue is, in order for the pressed in hub to clear the parking brake assembly it has to be shimmed outward about 1/4". This shim fits between the bearing, and the hub, and is a part of the retrofit kit. It works well as far as clearance is concerned, but my worry is that the hub is now riding on less bearing surface. So the question is, has anyone else used this system in the past? And if so, has anyone had any issues with the hub coming loose, or bearing wearing out prematurely. It's seems like it's just like installing huge offset rims to a regular unequal length control arm car. It would load up all the items on your suspension from the spindle to the ball joints. Also with the t-bird type IRS, there is only about an 1 1/4" of bearing to begin with, very similar to front wheel drive cars. Any advice would be appreciated.
Thanks in advance.
