Who's making the move to STU?

Is it the steering knuckle I have to worry about? Currently, I have about 3/4" of clearance, I'm estimating. Going down an inch in diameter will move the wheel slightly closer to the knuckle. I'm guessing it'll give me another 1/2" to work with. Total guesses, though, without actually measuring.

I think I'll be taking a bit of a plunge on behalf of the current thread topic. Looks like I'll be picking up a set of 18x11 square Forgestar F14s (or Gramlight 57T, haven't decided yet).

Probably going with a 18x11 +25 all the way around, with a few different sets of spacers to give me options. Per the math, I need +21 to match my current fitment and would expect that to give me about 7.5mm clearance inside at the narrowest point to the arm, depending on how the 315 tire itself sits out from the lip. That's based on a rough measurement, so I'm trying not to get down to the millimeter on the inside.

I figure if a spacer is necessary, with a 5mm spacer I'll be only millimeter off of my current setup in the front, and even with the extra tire meet it won't be looking like a formula car. If I have to run even more spacer, well I'm already rocking #44 so maybe it'll just be another silver Mercedes.

On the rear it's obviously not as much of a concern, and 10-15mm of spacer will probably get the aesthetics handled.

Fingers crossed. I've been talking to Brendan, but if anyone else has measurements that make me crazy, speak now or forever hold your peace.
