Default With a 4" narrowed rear

What kind of backspacing would I use when ordering street wheels to maintain proper centering after taking 2" off each side of 9" rear? I know the rear will be narrowed, so want to get a set of wheels ordered up for it. Thanks.

I think it would be 6 inches of BS on the wheel, mine are 5 inches and my rear is narrowed 6 inches total. Its too early to do math

I was thinking the stockers are something like 7.5, or maybe thats the Weld Prostars? So wack 2" off each side of the housing, and add 2 to the wheels, 5.5? Where as 5-6 should all be goes. I'm looking at a new set of street wheels, and when I order them I want to give them the backspacing I want and dont want issues of hanging out the wells or rubbing the entire in fender. But, I think the math above is close enough.

I'm running 3" narrowed per side with 5" bs and my 10.5w's are really tucked up in the fender. If you search my posts, i put some pics up a few weeks ago.

It would be 4" of BS on a 4" narrowed axle. It would be 5" on a 3" narrow and so on. You can gain an additional inch size when you narrow an axle because stock width axles can only get the largest BS of a 7 or 7.5. There is room for an 8 on a stock size but no one makes one. So, just subtract from there. I don't know why you would necessarily want a 4" narrower axle as it might cause some issues with some of the mounting hardware.

Derty, I think he means 4 inches TOTAL, not per side.....3 inches per side is max as far as I am concerned...even at that I had to have my panhard rod mount moved over and my panhard rod shortened accordingly, but my park brake cables do work..as many said they would not.

Good point. The math lesson still applies. So a 6" BS for one narrowed 2" per side would be pretty good. Sounds like on yours the panhard rod bracket is in the wrong spot by just a tad. When you narrow the axle, the stock suspension geometry should not change and it should bolt up the same. Granted, having an adjustable one should help center everything up. But, ideally that shouldn't have changed too much.

BTW the Convo Pro's I got from you look KILLER on the car.....although I am considering a set of Holeshot wheels...but these look good, thanks.
Hey give your opinions on my other post in this section on whether or not my wheels are too far under the fender.

Derty, yep, thats 2" per side, might go and do the 2.5 or 3" but not sure yet. I do plan on racing a lot more once I get back to the mainland though, so 3 might give me more room. I am looking for a set of street wheels, something kind of light, kind of nice looking, but not super exotic like Harts, etc. Looked at some Centerline...Cruisin Customs Meteors: http://www.centerlinewheels.com/imag.../563meteor.jpg

Or some Orbital 2000- Archers: http://www.centerlinewheels.com/imag...er_451x421.jpg

I just want to make sure during ordering that I get the wheels to mount up under wells, not protruding out like some old skool ****. Wanting to go fat in the back and normal up front for the street. Of course, the same info will be used to order the Bogarts too, looking at D-10's with Gold Anodized center as of now. Thanks guys.

Found them, very nice tuck to it. Will now be considering the 3" per and 5" BS. Now to make sure the street wheels can be had in that pattern Of course on a 17" rim though. Guess I could go 17x10 rear and 17x7 front for a killer street stance. What size rim do the 315's need, 10"?

IMO none of this is needed with a 17x10 and a 315/35/17, unless you want a "dish" in the wheel offsets are easily had to tuck that under nicely.

yeah 315s fit nice on 17 x 10s. If you want some more pics of my drag rims let me know. I finally got some weight back in the car so its actually tucking the tire up in the wheel wells now insted of sitting in 4x4 mode lol.

Sorry for not posting up earlier.. I plan on running 28w's for track, but with a narrowed rear I know I wont be able to use stock wheels. Unlike many that would run an additional set of 15's ProStars or something, I want to run 17's or maybe an 18" rear and 17" front. Either way, I know a guy here running a 17x11 on his SS, but try doing that will a stock BS wheeled on a narrow rearend and scrub scrub scrub!

69vette, if you can dig some pics up feel free to email, cat3n4@gmail.com
