Hey bro!

I recently fitted new wheels on my G30.

I think those offsets are too aggressive for G30. I got 20x9 ET20 and 20x10.5 ET35 with 265/35R20 and 295/30R20 tires. This fitment is very aggressive and I am rubbing with large dips/bumps on the front and interestingly the rear left, but not the rear right.

You might be able to get away with a little more aggressive offset/size on the front if you roll the fenders. Unfortunately, camber isn't adjustable unless you get new upper A-arms/wishbone control arms.

For the rear, you can probably adjust for more aggressive negative camber (right now I think have around -1.7 degrees). I'm taking it in next week and am going to ask for -2.0 degrees to hopefully prevent my rear left from rubbing. Personally, I wouldn't go any more aggressive than what I did.

In hindsight, I would've gone 20x9 ET25 for front and 20x10.5 ET38 for rear to give a little more breathing room.

So my brother in law recently had a F10 535, and is looking at getting into a new G30 540...maybe 550. He still has his Forgestar's from his 535. Any idea if their fitment will work on G30?

Front: Forgestar F14 Deep Gunmetal Gloss 20x9.5 +22
Rear: Forgestar F14 Super Deep Gunmetal Gloss 20x10.5 +35
