But that's also where the "conflicting information" comes in... The GT2 has a thinner wheel liner, AND my car is lowered... lower than GT2 height with my H&R's? I don't know. H&R's website says it lowers the rear by 1", but 02996x50 says his drop was about 1.5" with the same springs.

Unfortunately, the springs were on the car when I bought it, so I'm not entirely sure just how much of a drop in height I have vs stock. So, for my situation, if a 44 offset was better than 45, to give me more inner clearance, I'd choose that.

At this point, I'm thinking 43 could be the number, because 2muchtime is running a 43 offset with his spacers to clear a larger turbo, and 02996x50 has made it work with 40 offset, BUT fenders are rolled.

It's clear I need to err (if I do have rubbing issues) on the fender side, so I have the option to get them rolled, rather than on the strut side, where a spacer would be my only option.

I wanted to do the same thing...i went to Tire Rack, put in GT2 and it gave me the available sizes and correct offsets. I bought OZ 12x18 on rear. I have PSS10 lowered +or- inch. close fit but no rubbing.

rolling them is a non issue.. as long as you have qualified help ( if you're not a diy' r) it is less daunting than it sounds. but you're on the right track. erring on the fender side about right. also, my stance is at least 1.5, and may be closer to two inch drop.. it's pretty low, and obviously i think the 40mm frt/rear is optimum given the tires i like to run but et 45 rear should work without rubbing. again, the hammer sounds worse than it is should that become necessary. there's gotta be someone around without rolled fenders using the 12" rear absent issues?!

which i could be more certain, but i'm "pretty sure " that 40 will work, bolt on, no problems.. but.. ya know. if you're ordering f'stars, the place you order from should be able to answer this with a bit more certainty. PRE order. also, per pdrwounds suggestion, ya can't go wrong with gt2 size/offsets. i went for the extra .5 in. up front. love it.

Yeah, I definitely want 9" in front, and a 40 offset should be just fine for those. The rear... I think I'm going to get 43, that seems a good compromise if I ever want to get larger turbos (doubtful, but who knows) and having to buy GT2 inner liners, vs having to roll the fenders.

(Frankly I have no idea what is involved in rolling them, I am a pretty handy DIY guy, but I haven't researched how that is done at all.)

Looking forward to hearing what 32krazy says about his fitment as well.

Thanks for the help so far everyone, I love this forum!
