Hi Guys, my 70 Lark has Cragar Street Pro wheels on it. I have the 17x9 with 5 1/4 backspacing all around. I like the wheels but I really like a more 70's muscle car look with deep dish in the rear. Cragar sells this wheel in a 17x9 with 4 1/2 backspacing, my question is do you think it would make a visual difference worth the investment to put those on the rear? I cant find actual pictures and I wonder if less that an inch of backspacing would even be noticeable? http://www.jegs.com/p/Cragar/Cragar-Chrome-Street-Pro-Wheels/752604/10002/-1
Going with 3/4" less back spacing will move the wheel out 3/4" Do you have that much room between the tire and outer edge of the quarter panel or fender? My guess is no.
I was going to mention that too, but I assumed he realized that. I'm in the wheel business, so maybe that was assuming too much
Maybe. My pet peeve is when I see the terms offset and back spacing used interchangeably. I'm sure being in the wheel business, you see the same thing.
I do have room in the fender well. I understand what the numbers mean, that is why I was asking because 3/4 of an inch does not sound like much but maybe it is a noticeable change? sorry if I used the incorrect lingo, did not mean to irritate any wheel guru's. Just looking for any educated information or advise before I spend over $500.00. I like the wheels but I was just looking for more of a 70's style with a deeper rear. this is my only option other that replacing all four, which I may end up doing.?
I don't know how you change the depth of the wheel on the outside without changing the back spacing. Not sure how you have that much room, but you are there and would know. BTW, I wasn't irritated:grin: Just hate to see someone make a costly mistake because they used the wrong term when ordering wheels. Offset and B.S are related, but very different things.
OMG - I see & hear everything! We don't use backspacing & neither do the OE's but customers refer to it all the time as fo many aftermarket wheel companies, but except for clearance issues, it has no relevance. And then there's positive & negative offset, etc. & every manufacturer has their own convention. We've gone to using inset (rim centerline inboard of the wheel mounting surface) and outset (rim centerline outboard if the wheel mounting.surface) for single type wheels because it's more intuitive and offset (centerline to outside face) for dual wheels because that's how dual spacing is determined (I.e. 2x offset = dual spacing, which in other words is center to center of the rims) and that's what the tire manufacturers (actually the Tire & Rim Association) specifies. I could go on & on, but...
I don't think you said anything to offend - I took it that Larry was just making more of a general statement. Happy to help although for someone who doesn't understand as you seem to, I omitted a critical piece of information giving you the benefit of the doubt that you already knew how the clearance would be effeted (or is that affected?)
