wheel "experts" I need help with offset/back spacing for custom built wheels I am getting ready to order a set of iForged wheels and need help figuring out the proper dimensions.
I currently have the 17x9.5 and 17x11 TT IIs.
I am going with an 18x9.5 and an 18x11.5 with 335s on back.
If I am correct the standard back spacing on the 17x11 TT IIs is 7.75" with a 45.72 offset.
With adding the additioanl .5" to the back side of the wheel this will change the back spacing to 8.25"
With the wheel being .5" wider it changes the center line of the wheel so how do I figure out the offset?
I want the wheel to sit the same as the TT IIs do at the fender well lips edge.
I know it is going to be an extremely tight fit but with the correct measurements they will fit...I hope <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
I am not worried about the fronts because I am usng the same dimensions as the TT IIs.

Re: wheel "experts" I need help with offset/back spacing for custom built wheels I have 18x10.5" rears on my car with a 58MM offset. They are very tight on the inside. If you added an inch to the outside of mine, it would put the wheel at the very edge of the fenderlip. I dont think I could go any further on the inside without doing pretty significant modifications. My car is also lowered a little more than 1.5". Let me know what you end up doing for an offset and how it somes out. I would like to order the HRE's in the same configuration as you are doing your wheels. <img border="0" alt="[USA]" title="" src="graemlins/patriot.gif" />

put some 19/20 iforged's on that sucker! (like the HRE's you had on your WS6) <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
your past WS6 gave me inspiration for my 19/20 setup! <img border="0" alt="[worship]" title="" src="graemlins/gr_hail.gif" /> <img border="0" alt="[worship]" title="" src="graemlins/gr_hail.gif" />

Re: wheel "experts" I need help with offset/back spacing for custom built wheels TrilogyZ28, I may end up doing 19/20s next year depending on how well these wheels fit and if I think I can get about another .5" to the inside of the wheel well. I may have to mini tub the car to do it but think 20x12 HREs with a
