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! |
Thank you! The wheels are going to be custom so any offset within reason will be available. Thank you for the wheel calculator link. So with the 4.2% difference being >greater than the "under 3% rule" is why you are going with 18's because 17's don't come in 35's but only 25's and 45's, is this correct?
Going with 9" fronts and 10" rears, what's the closest to stock drop and camber that can be run without hitting any of the break line brackets or other parts inside the wheel well if we use the offsets for the RPF1's from your example above 35 offset front and 38 offset rear?
