When you select product options for a specified vehicle it shows the offsets. The 8.5s are +30, the 9.5s are +15 to +45, and the 10.5s are +45.
Odd, it didn't show that for me. Did you see the weight anywhere?
I did not. Maybe the manufacturer's web site has them.
Any wheel that's rotary forged (flow formed) should be way lighter than stock wheels.
When I went back in, I did see where the offset info was this time. Problem was I had selected the 9.5" and was hoping for more detail than -15 to -45. The manufacturers site doesn't even show that model (discontinued?) and doesn't show weights for any of the sf series wheels. To me, when it's too hard to find basic information, that's a red flag.
That's not necessarily true. Most flow formed wheels are 23-27 lbs (assuming 19x10, since that's what I've been looking at). My stock, black accent pkg 19x8.5 are 26.x lbs, so most flow formed wheels are slightly lighter, some aren't lighter at all.
Well of course size will make a difference. PP1 wheels are over 30 pounds. Moving up in size without increasing the weight is still a win.
at least 15mm. and you'd need longer studs. Otherwise you can run up to 25mm for pushing them way out. The spacers are cheap. buy a selection and slap them on and drop the car back onto the ground and see if you like the various settings. do NOT drive on them though until you've gotten the studs or bolt-on configurations correct.
