4.56 FD Swap Parts and Labor :)
Just got back from getting the final drive swap completed by a local shop in the NW area. Got the ring/pinion and the install kit from weir performance for a little over $400
 ~ Found a shop in Portland, OR that had done SEVERAL final drive swaps on the 86 platform, and he's incredibly fair for his rates! Got the entire labor complete for around $370 $300 for labor $70 for supplies  It was done in a single day. I just need to change out the fluid in around 1000 miles after the gears have broken in. Absolutely NO whine at all from incorrect backlash. Entire car has more torque, and when this mod is paired with E85. I don't believe there is a better NA setup that you can do!!  [ame="https://www.youtube.com/watch?v=occuNSTlkIo"]UEL E85, 4.56 FD swap 0-80MPH - YouTube[/ame] Just wanted to share my experience

I think FD changes are the best way to change the driving experience of this car, be it up or down.

Backlash would make a deccel whine and pinion depth would make and accel whine.. both are very important. i just took out my gear to prep for turbo.. it feels like my gears got so long going 4.1

It's quite dramatic. First gear is still necessary/usable but second is no longer too tall for tighter switchbacks. Second-third-second transitions are a joy.
The corn juice doesn't hurt either.  Well done!

Added a quick 0-85ish video so you can see how much the shorter ratio affects car
