BBS RIA, anyone running 18x10.5 ET25 squared?

Hi Guys,

Anyone running 18x10.5ET25 squared? I know the front will need a spacer, but I'm more concerned about the rears since the offset is pretty aggressive.

Whats the minimum negative camber for the rear? Any rubbing on the inner fender with let's say -2.0 deg?

Also I'm planning to run either 295/30/18 or 285/30/18.

Thanks,
Steve

I don't run that set up but I researched it extensively before just going with 18x10 et25 since I decided to stay with 275/35/18 tires.

There's at least one member here who has run 18x10.5 et22 with 295/30/18 who clears the rear fender with camber in that neighborhood. If you search 18x10.5 or slicer spec you should come upon that thread.

The RIA in 18x10.5 comes in et22, et25, and et37, I was very close to pulling a trigger on et22 in hopes of clearing the front inside w/o a spacer and also clearing the rear outside with camber and height. There's so many variables I felt I would be running a "compromise" fitment on both front and rear. IE, what if et22 fits but only leaves 1-2 mm of room inside front, or 1-2mm rear fender? Would it flex and rub under hard cornering? What if I wanted to try a tire that runs wider? It jus didn't leave enough room for error on either axle. Ultimately I stayed with 18x10 but if I were to go 18x10.5 squared in the future, I'd go with the et37 which ensures fitment in rear, and run a slightly larger spacer in front (easier to add spacer and reduce offset than vice versa).

Let us know how it turns out. Beautiful wheels, I like them so much I bought 2 sets lol
