If you choose custom wheels like forgestar, you can choose the offset. Or better yet, you tell the manufacture what you want and they choose the "perfect offset" for you!
Now, tires. Staggering 17's sucks. You can't get 35 series. So you have to go bigger on the front to match. If you go 245/45 front you can go 275/40 rear for the same OD. Stock Diameter is 24.62". 245/45/17 is 25.68" or a 4.2% difference. the rule of thumb is to stay within 3% or less.
Here is a tire calculator. use it to find tires that are as close to the same OD (outside diameter) and different widths.

All of this is why I have staggered 18. Good luck! |
Ah Ha...not the 1980's band, the light bulb in my mind went off after I went to your link and put in OEM tires on one side and plugged in 275/45/r17's compared with 275/35/r18's:
The rear tires using the 17's would be traveling at 70mph when your speedometer was reading 65mph, were as using the 18's at 35 sidewall the difference is halved at only 67.5mph actual while speedometer is reading 65
and using 25's on sidewall with 17's goes the other way significantly....good call on the 18's...now I hope my custom shop will be able to make 18's in the style I want, hahaha
