Enkei has an RPF-1 in a 17x9 +45. I wanted to run that on my S13 when I was looking at 275's. It'll clear even with S14 subframe. The S14 adds 10mm width total. That is, 5mm per side. That S14 subframe is the ticket for more squat. If it's still not enough, space the front points down 3/8-1/2". I think blackwhite(?) Dan runs 275 555R's on his S13 with 9+35's. Looked like a little roll but nothing major.

Again with the wheels. Jeez. There's this thing called "engineering" that you guys are missing. Not to mention this thing called "metalurgy". Shitty material plus shitty design = failure prone. It's not just QC. You can batch test all day long, but it all does is make sure your product meets a minimum shittyness requirement. Don't assume these failures are from singular manufacturing defects. I'm asserting that the failures are due to the combination of design and manufacturing processes.
