that cant be.........because the wheels are the same width front to rear, if the offset changes so does the back set the equal amount. | |

Positive Offset A positive offset occurs when the hub mounting surface is on the street side (the side you see) of the center line of the rim. Most factory rims will have this type of offset. Zero Offset When the hub mounting surface is centered within the rim, it is known as a zero offset. Negative Offset If the hub mounting surface is on the brake side of the center line of the rim, it is considered a negative offset or "deep dish". http://www.discounttire.com/dtcs/inf...Mlw9pkpS2dvzfQ The easiest way to measure backspace is to lay the wheel face down onto the ground so the backside of the wheel is facing up. Take a straight edge and lay it diagonally across the inboard flange of the wheel. Take a tape measure and measure the distance from where the straight edge contacts the inboard flange to the hub mounting pad of the wheel. http://www.rsracing.com/tech-wheel.html#backspace I measured my Pede wheels. Overall width was 1.884". Fronts Offset = -.304" (negative offset) Backspacing = .638" Rears Offset = +.166" (positive offset) Backspacing = 1.108" I was incorrect in that the offset is not all that close. Sorry. However, can you see how 2 wheels with the same offset (one being positive offset and one being negative offset) could have very different back spacings? I was just trying to be a smart azz since you did not specify positive or negative offset in your post. | |

| Thanks Chris, I never really understood "negative vs. positive offset" 'til now! I had a salesman from American Racing try to explain it to me once, but he didn't know what he was talking about and only confused me more than I was already. Backspacing I understand, that's something I can measure with a yardstick and a tape measure. Quote:

Glad to help CSR. Most people do not understand the differences and mix up the terms (look at alot of the posts about wheels) I just saw an opportunity to post that info and thought it would be helpful, luckily Rockwerx took the bait like Fishy said. | |
