So if I widen the inside of the 17x7.5 +30 fronts by 1.5 inches and the rears by 2 inches, that will give me 17x9+49 in the front and 17x9.5 +55in the rear. Would this be an acceptable width at stock height and little or no fender work?

Don't forget the cost, you are looking at $1k for a full set. In some cases widening is the way to go to achieve specific results, but for a typical 9" +45ish fitment there are plenty off the shelf wheels that will work.

Holy moly.

Yes your calculations are correct. A 17x7.5 widen on the inside 1.5 inches would be a 17x9+49 and 2 inches widen would be a 17x9.5+55. But this would be point less because it cost $250 to widen a rim. Your better of selling your rims and just buying rims in the correct size that you want.

The purpose of me doing this is to fit the widest tire possible on a stock body. This would be a 295 size tire. Then no ones makes the correct size rim with the correct size off set. That's why I custom widen rims to a 17x11.5+63.

Beautiful. I'm going to go this route in the future as well with my Gram Lights 57c, also 17x9.5 +38

do you think that the structural integrity of the wheel has been compromised at all?

There is a large debate on this topic. Some people say yes others say no. The obvious concern/problem is you're heating the wheel unevenly and getting it very hot where the welding occurs which could lead to failure.

Strange that you would weigh in now. Your the cause of all my problems. If your 57c's weren't so damn good looking, i wouldn't be trying to buy some and make them fit.

As I said Junky has been running this setup for years (and a lot of miles) and weldcraft does this for numerous different applications. I am not sure what would happen it they had a serious impact but outside of that just driving hard they should be fine.

Anytime someone modifies something outside of the original manufacturing process I suppose there is always the potential of some form of failure, usually with poor craftsmanship. when I had this done originally i went with someone who has been in the business of modifying wheels for motorsports racing for decades, learned about the process and decided it was safe to pull the trigger. Ive been running my widened rpf1 on these 295 for about 6 years now in the back, they have seen a lot of road miles and several track events. I more recently had the fronts done as well to accommodate a 255/big brake offset.

No risk no reward. Cool to see some following in my footsteps and some others considering, not that widening wheels is anything new, but doing it on an S2k with the mentioned tire option, is. Just consider the mentioned reasons for doing this, there is no point if the wheel can be had off the shelf to accommodate an average sized tire that would otherwise fit by other measures. And also consider that this 295 in a 17 may or may not be available in Kuhmos new XS replacement. No other manufacture currently makes a 295/35/17 and the current XS run has been discontinued since 08 with all known replacements now gone off the shelf. The v720 will be your only potential option to run this size tire starting in spring of 2015. so if anyone is considering doing this, wait till then to insure you have a tire.

The better option I think at this point would be to just run 18"
