I've looked tired to look for my answer but couldnt find it what is the lowest offset the gs300 would be able to do. I'm looking into 17x9 +15 but I'm afriad it won't fit cuz of the offset I see everyone on here around +35 and +40.

 

It'll fit but poke a bit on the front without being low and having having camber.
This is 18 x 9 +35, and I had heaps of room on the rear, but the front sat decently. You'd be looking at 20mm more aggressive.
3 deg camber on the rear, 2 on the front.

 

Yeah, it will poke a bit. Nothing a bit of camber and a 235 or 225 tire can't fix.

I'm running 18x9 +20 with 235s and no additional camber and haven't even had to roll my fenders.

 

Thanks guys I found some other wheels that are the same just with a +35 offset

 

I have 18 x 9.5 +15 in the front with a 225/40 and it sits perfect. Although I'm running like -6* of camber haha

 

The car is all stock I had a ball joint snap while I was driving and I'm currently looking for some wheels cuz I'm riding on a spare wheel
