Thanks for taking time to share the specs. What size rear tires are you running and how flush do the front and rears sit relative to the fenders? I like it really tight, but no poke.

My fronts are not as flush as I wanted. You can do +32 in front with a 9 inch tire. Or +38 with a 9.5. You have plenty of allowance in front to be flush. My rears have a little allowance but they are flush. Please check my thread for tire sizes. Thanks

Don't think I'm going to go 11s as I can't stand the stretched look. Everyone with 11s, based on my limited search, has this exact look I personally dislike because the metal sticks out. Too hot import nights for me.

Sounds like ideal tire sizes are 245/30s + 285/25 or 295/25? 20x9 up front and 20x10.5 in the rear? Maybe I should go 20x8.5 up front to make the 245s cover the rim OEM style.

Thx.

Lol in order to stretch a 305 you'll need a 12.5" rim

Final wheel and tire specs blessed by Work. Hope this helps others who want perfect fitment. If you guys want a hook-up with an authorized dealer, lmk. They're cheaper than anyone else I've received quotes from.

What I consider to be perfect fitment: Non-stretched tires (i.e. square profile). No rubbing full lock, full compression even when lowered (i.e. OEM fitment with aftermarket flush look for that bulldog stance).

CV202, gloss black lip, matte black centers w/ matching caps, black Work lugs
20x9 ET38, 245/30 MPSS
20x10.5 ET45, 285/25 MPSS

2-3 month wait (patience tested)

For the rears, do you mean 285/25? That's a really low profile in the rear, but I know it'll work according to the specs. Patience will be tested, that's for sure. The entire wheel being black will look pretty stealth.

+45 is ok as long as you are not going to be really low. Otherwise a +50 would be better IMO with maybe a 295/25 rear. I think you should be ok maybe a slight shave on the rear if it does rub at all but nothing huge

murph man, having the darndest time nailing down offsets as calling the Work Wheel guy in Cali, though patient, wasn't too much help in finalizing the numbers for ISF fitment. They don't have any recommended sizing for 20x9, 20x10.5s with close to stock diameter tires in 245/30, 285/25. Pretty much have to lean on you guys end of day.

What's really low? I just want zero wheel gap in the rear lowered like this one:

http://www.iputinwork.com/?p=3662


So are my specs below too aggressive given my fitment requirements?

20x9 ET38, 245/30 MPSS
20x10.5 ET45, 285/25 MPSS

or should I be looking at pushing it to 43+ up front and 50+ in the rear?
