Monte72Carlo Posted February 15, 2009 Posted February 15, 2009 Any one here running them? I currently have my drums all rebuilt and installed but it turns out my backspacing on my rims is about 2-2.5" wrong and was wondering if rear disks would bring them in? as rims are about as expensive as the kit. Thanks, Garrett. Quote
monte70car Posted February 15, 2009 Posted February 15, 2009 we have 4 wheel disc on everything what is the backspacing you have now Garrett? i don't see how the back spacing is rubbing the drum if anything it would rub the wheel well. i run 4.5" backspacing on a 8" wheel. Quote
Monte72Carlo Posted February 15, 2009 Author Posted February 15, 2009 I have a 10.5 inch wheel with 4.5" backspacing and I need about 6.5" to clear the quarter. Quote
Mike 57 Posted February 15, 2009 Posted February 15, 2009 A rear disk kit will not change your axle width, the drum comes off and the rotor goes on in its place. Quote
Monte72Carlo Posted February 15, 2009 Author Posted February 15, 2009 alright thanks, that was what I was looking for. Quote
Sam (Bones) Posted February 15, 2009 Posted February 15, 2009 I have a 10.5 inch wheel with 4.5" backspacing and I need about 6.5" to clear the quarter. you won't get those wheels to work unless you raise the back of the car to clear them, I have 15x9's w/ 5 1/2" of back space and it barely clears with a 275/60R15 Quote
FerrariTruck Posted February 17, 2009 Posted February 17, 2009 I think you would be better off shortening your axle. Its about $200 or less to get it done. I'm doing this to my car cause I got a great deal on moser axles with c-clip eliminators but for the shorter 12 bolt that uses 29.5" axles. If you do this then you can shorten your axle between .5" to 1" but you will have to get the axles splined to go 1". Again this is a way to do it for less, but the best way is to just get the right wheels Quote
Monte72Carlo Posted February 17, 2009 Author Posted February 17, 2009 Sam, are you sure cause I have about 2 inches left between the rim and lower shock mount as it is which allows a 6.5" backspacing. What are you concerned about them hitting? Thanks, Garrett. Quote
Sam (Bones) Posted February 17, 2009 Posted February 17, 2009 mine hit the shock bolt with 5 1/2" back spacing, and a 9" wheel, barley clears the outer lip of the quarter panel, you're saying the shock mount put the shock mounting bolt in there, I'll bet you $$$$ that a 6 1/2" or even a 6" back space won't work, even if it does, your tire will rub on the inner wheelhouse (unless you have modified it) (been here, done it) Quote
Sam (Bones) Posted February 17, 2009 Posted February 17, 2009 you might get away with 6" back space then,IF you relocate the shock bolt like I did Quote
Monte72Carlo Posted February 17, 2009 Author Posted February 17, 2009 With the centerline wheels that I have right now I DO have at least 2 inches worth until I hit the BOLT in the shock. Sorry for any confusion. It might be that I have less backspacing than I was told (4.5") but if I'm correct on the backspacing I should be able to clear with a 6.5" wheel. Garrett. Quote
502ci Posted February 17, 2009 Posted February 17, 2009 He went for nice looking tubs. Unfortunately they are "just" tubs...the frame is not modified in any way and the tire will rub on that if he goes too far in. My stock inner wheel housing on my car is massaged as far back as the frame and I know 6.5" of b.s. would not be good. Bill Quote
Monte72Carlo Posted February 17, 2009 Author Posted February 17, 2009 Here I went to the garage and took some pictures of my problem: shock mount has 21/4 inches of clearance: Frame to wheel clearance has about 3 inches: From my measurements 6.5" should work Garrett. Quote
monte70car Posted February 17, 2009 Posted February 17, 2009 Garrett you don't have 4.5" backspacing. that looks more like 3.5" to 4". it looks like you have a deep dish wheel. Quote
FerrariTruck Posted February 17, 2009 Posted February 17, 2009 yeah that looks like 3.5" of backspace. the edge of the rim pretty much lines up with the brake drum. this is what 4.5" backspace looks like Quote
Monte72Carlo Posted February 17, 2009 Author Posted February 17, 2009 Well then all the better cause I only need 5.5" backspacing but I might go 6 to tuck up nicely under the quarter. 6.5" is hard to find in common wheels anyways. It doesn't look like theirs much more space between your lower shock mount than mine. I think it's just the different angle. I'm pretty sure I have 4.5" (how would you measure?) Thanks, Garrett.

502ci Posted February 17, 2009 Posted February 17, 2009 If that link isn't enough for you try this... 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. This measurement is backspace. The above photo shows three wheels with 2",3", & 4" backspace. Bill Quote
Monte72Carlo Posted February 17, 2009 Author Posted February 17, 2009 Thanks for the site, based on how to do it on that site I got 4.5" of backspacing. so it looks as if I'm going to need a rim some where around 6-6.5" Thanks, Garrett. Quote
