I was wondering, if you take a wheel and have the back of the hub ground down to add say another +6 - +10 mm of offset, how then is the structural integrity effected? For example, if you have a Weds Sport TC105N at +49, and want to make it a +55, could that be done and the wheel still be track worthy?

 

 

the 17x9 +49 wedsport is very good for the s2000, fitment wise. less aggressive than a +45 and doesn't require you to roll the fenders all too bad with 255's. i wouldn't recommend grinding down the hub area of the rim. some manufacturers are okay with it, but I believe it's only like 5mm.

 

Im not willing to roll fenders but really love those wheels :/

 

Any reason not willing to roll the fenders?

 

The thickness of the hub on the wheel will definitely effect how strong the wheel is. What would be interesting is if you could look at the design of the wheel with a higher offset and compare it to the wheel with a lower offset. Are they identical except for the shorter protrusion of the hub? If so, then grinding it down is probably fine. However if the hub material is kept roughly the same and the shape of the wheel is altered instead, then it probably isn't safe to grind anything down.

FWIW, I have a degree in mechanical engineering, though much of this is common sense.

 

^^^I hear ya. I was just thinking that because of safety tolerance levels there might be some play room in there.

looks like crap (if not done right...and I'm not willing to risk it) + devalues the car. I don't even want to relocate tabs if I can help it.

 

How about run a 245/40 and add a little bit of negative camber and call it a day?

 

How about the 17x8 up front? Stock tire sizes. Otherwise id go higher offsets.

 

I'm also very curious about this as well. I don't think offset matters b/c while the back side might look thicker/thinner what matters is how much material there is between where the lug nuts seat and the back of the hub. If you look at lower offset wheels the lugs nut usually go deeper into the hub area. I would say you might get away with 2-3mm ok but beyond that I wouldn't do it. I'd just look for a different wheel that is made in the size you want.
