Well what I have figured out is that if you call a company about rims they will make the offsets perfect for your car... now if your trying to buy cheapo rims from ebay then I guess when more people get wheels and post there offsets we can update this with users offsets...

exactly, some of you guys had to have called manufacturers or other places about wheel offsets. If you didn't call but have wheels that fit properly in the fenders, please share what you have learned so other can make wheel decisions! these findings will most likely be different for the cars that have the sport brakes vs standard so please state that.

Thats great MaxtotheG37, maybe add if you had to run negative camber to get the offsets to work, and how much negative camber..etc...

Great idea, I hope to have my 20" Volk GT 30 from Sharif mid March. I wish this data was complete now because I'm trying to figure out how much tire I can stuff under my G and how much drop I can get away with, without hitting. I know Sharif and others have clearly stated that Front 245/35 20 and rear 275/30 20 will not hit with the S.Tech springs. Others are running Front 255/35 20 and Rear 285/30 20 without any drop and no hitting. I really want the most rubber I can get and the most drop without hitting. I’m thinking the larger sizes with maybe less of a drop?

As stated the recomended tire size for the Volk 20" GT30’s: 245/35 20 front and 275/30 20 rear with S.tech springs. I did some calculations and that size tire has a .22” smaller Outer Diameter (OD) than stock. I looked around and did some more calculating and came up with the option of running 255/35 20 Front and 285/30 20 Rear, the OD is almost identical to stock. The offset is not the same.

Stock:
225/45 19 F Larger than stock rear .26"
225x.45= 101.25mm
101.25x2= 202.5mm
202.5+482.6= 685.1mm 26.97” OD

245/40 19 R
245x.40= 98mm
98x2= 196mm
196+482.6= 678.6mm 26.71” OD

Possable opion:
Front
255/35 20 Larger than rear below .29"
255x.35= 89.25mm
89.25x2= 178.5
178.5+508= 686.5mm 27.02 OD .05

Rear
285/30 20
285x.30= 85.5mm
85.5x2= 171mm
171+508= 679mm 26.73” OD

Anyone know if 20mm spacers in the rear will work well with the OEM wheels/tires? I do have the RAS package.
