I get a very slight rub occasionally. I noticed it once on passenger side when had the wheels turned right as I backed up into a hill of a driveway to turn around. I want to see if I can somehow shave off like a half an inch of the very corner of the delete caps. The lower spacers definitely dont feel like they have been detrimental to the ride at all. Keep in mind though that the added bit of preload probably is actually helpful for me. Between the DV8 bumper and the winch, i now have over 200lbs more weight on the nose. As far as the CV angles go, you can definitely see a downward slope of the axles and lower control arms, but it doesn't look too bad. I haven't used any mode of 4WD yet though. The snow had gone for the season and I haven't been offroad yet. Time will tell on that. I suppose it could possibly shorten the lifespan of the axles, but it doesn't look like there's a chance of any binding. The angles are not drastic. I will take some pics tomorrow if I remember and post them.
