cost $240 per rim to cut and weld in any width band you want and the best part is they balanced out better, and had better run out than they did straight from rohana, also they give a structural warranty on the wheel for I believe 3 years garaunteeing their work.

What was the rear size and offset prior to you getting them widened?

original rear was 20x11 +10 added 1.5" to the back

and no not sluggish at all, there's no accel difference other than the fact that you can stand on the pedal right off the line and get traction MUCH faster, and with the wider fronts the turn in is twice as good as stock

I knew something wasn't right with your offsets. Your actual rear offsets are +29 and not +45. Here's how to calculate it:

Original wheels were 11" +10 offset. You widened them by 1.5" or 38.1mm. Now take that 38.1mm and divide it by 2 to get 19.05. You then add 19.05 to your +10 offset giving you a final offset of +29.

Hope that helps.

normally youd be right but in this case since the entire 1.5 inches was added to the back you do not divide anything by half because the whole additionaly 38.1mm was added all on the backside none on the front, and its only 45 not 48 because you lose 1/16th of an inch when they make the seperation cut

Nope. I'm 100% correct. I've widened wheels before. You're correct about the 1/16th part (or 1.5mm). So actually his offset is closer to +30 than +29.

1010TIRES.COM - Wheel Offset Calculator

Plug in 11 wide and +10 offset on the top
Plug in 12.5 wide and +29 on the bottom

Then try it with your numbers.

Let me know what you figured out.

This kind of stuff drives me nuts. The OP listed offsets that were completely wrong because they didn't know how to calculate the final offsets once the wheels were widened. Now people reading through this thread will come across that post and order wheels in that exact offset. When they get them and put them on, they will realize that the thousands of dollars they spent on their wheels went down the drain. Not cool in my opinion.

What the mods should do is go and edit his post for future members.

Bottom line is that if you don't know what your talking about or don't understand offsets, please don't post.
