[QUOTE="Augster, post: 1992755, member: 19867"] From my research, the most likely reason is because some positive offset (more backspacing) has the least chance of having the outer tire edge contact the lower rear portion of the fender liner near full lock to the left under articulation. Right behind it is the pinch weld between the floorboard and driver's side panel, which sticks out about an inch forward. One solution to avoid rubbing is to fold over and flatten the pinch weld with a hammer, or just cut off, then tack the portion of the fender liner straight onto the floorboard. You can't go too far deep inside (more positive offset) without the inner sidewall contacting the UCA's... Are you sure that RPG's have 1.5" uniballs? From the [URL='https://www.rpgoffroad.com/product/10-14-ford-raptor-billet-upper-control-arm-kit/']description on their website of their billet UCA's[/URL], it's 1"... [ATTACH type="full" alt="Screenshot 2024-01-23 at 5.01.16 AM.png"]441600[/ATTACH] SVC billets are 1.5" uniballs. But some have recommended the [URL='https://www.iconvehicledynamics.com/accessory/15638/icon-accessories-10-20-raptor-billet-uca-dj-kit/']Icon UCA's[/URL] because of their fully sealed and greaseable Delta upper ball joints, which is what I'm leaning towards, if not the SVC's. The GS 460's I run with both use Icon UCA's. I don't know where you're getting info stating you need -13mm offset to clear aftermarket UCA's, but SVC's UCA description specifies minimum 0 offset: [ATTACH type="full" alt="Screenshot 2024-01-23 at 5.18.33 AM.png"]441601[/ATTACH] As I mentioned in a previous post, I'm running 20x9+1mm and 35x12.5 and have no rubbing whatsover under full articulation and full lock in either direction, with plenty of clearance for an aftermarket UCA; it will definitely clear the Icons, I'm confident it will clear SVCs as I doubt 1 itty bitty millimeter will make any real-world difference with all the sidewall flexing that may occur that I'm sure SVC has allowed some generous clearance gap when determining a mimimum offset.
