If you do a search you will find a lot of posts advising against it, I however had gotten the Fat Man spindles before I found this site and was not happy @ all it dropped the car all right, right on the headers I had no clearance what so ever and they put extreme stress on the upper ball joints. And the bump steer was really bad... I went with the SC&C stage 2 kit and lowering springs it gives a really good stance and all most no bump steer. To really set it off I also recommend the LEE box to tighten everything up. I just did this upgrade last month and can’t stop driving the car because I just love the way it handles.
