I am gonna order a set of advan gt premiums but they are a custom order, anyone have any experience or know anyone that has used them on am LS if so what were the specs. I am going with 20x9 +47mm for the front and 20x10 +35mm in the rear. I want to make sure the spokes will clear the front caliper. Thanks

 

your offset up front is going to be way off.

 

How is the offset going to be off? my rims now are 20x8.5 +44mm and they barely clear the front caliper. I am doing this for a BBK.

 

GTs typically clear BBK with ease with their spoke design, so it should be okay. Not sure what wheels you're running now, but it's not always just about offset.

 

I have tsw mallory in 20x8.5 +44mm back spacing is 6.3 I think? Idk if that is helpful the gt's are 18lbs for 20x9 and 20lbs for 20x10 I was told by Vivid, that was my main reason for buying them.

 

That 9" wheel will be pretty tucked. Here's my 20x9 +35mm, if they do clear, your wheel will be sunk about half an inch further in than mine even. I wish mine were closer to +30 personally.

 

I understand what you are trying to do, but as stated below your wheels are going to be sucked in too far to look correct with the offset on the rear.

Good looking car, I spent a long time picking the offsets on my wheels and like you wanted, I ended up +30 front for mine.
