    hey lilcbra could you post some side pcs of the car. i want run 15x8's with 245-60's on the rear and something like what you have up front. the only problem is that mine is lowered all around. would still love to see some side shots though.:nice:

    manny-There is one side shot of it a couple posts up with the rears only, and there are a couple 3/4 side shots in the member rides section, I think on the bottom of page 8. If you are looking for something else, let me know and I will get some pics of what you are looking for...

    LiLcobra, what is the back spacing of the rear rims. BTW :nice: on the new look with the new rims. mine sits about the same up front but much lower in the rear.

    It is from a Fox body. It takes a little cutting and welding for the fill tube and the pickup (if you use a mechanical pump....for an electric pump, you might be able to use the stock location?), and there is one part of the tank that I beat for leaf spring clearance. I am planning on making a little video of what all was done and putting it on youtube, I have had quite a few questions about it. I just need to come up with the time to do it now....

    well i finally got to do it due to being lucky in getting some 17x8 and 17x9 cobra R rims from a fox body mustang. the fronts are 17x8 w/4.5 back spacing and bolt right on fine. the rear are 17x9 w/5.5 back spacing and i had to add a 1" spacer and they bolted right on. on all 4 fenders the lips have been rolled. 275x40x17 rears and 245x45x17 up front. and yes i am running the 1" lowering blocks out back and 2000 mustang GT cut coils up front, handles like a slot car now :nice:

    You can't put up a post like that without pictures. I think it's against the law...

    I bought one of those WheelRite devices that allows you to measure different backspacing/diameters/heights of wheels and tires. Based on that I ordered 15x8 wheels all around, with 3.75" backspacing in the rear and 4.25" backspacing up front. I'll be going with Granada rotors/calipers, which add 1/2" up front, bringing the wheels all to the same spacing. I'll post up pictures when I get everything installed.

    agree with needing the pics.

    i am running 15x4 up front and would like to go with a wider wheel. i have 15 x 7 on the back but they did not even come close to fitting up front. my king is lowered 2" in the front and 1" in the back.

    I can't even imagine driving a King Cobra with a 2" drop in the front. Doesn't that mean you catch your airdam if you drive over a dime?? Even with the standard ride height, I take every driveway and approach at as much of an angle as I can, and as slow as possible. Yes, overcautious, but...

    it does require some careful driving. my driveway has a pretty good uphill pitch from the road and it takes a few minutes to get the car in and out without hitting the airdam. one of the problems i have had is when turning and the spring goes into compression the tire will hit the airdam where it wraps into the wheel well. i quickly learned how to drive, so it doesn't happen but thats why i always question wider tires on the front of lowered cars. i just can't seem to come up with something that doesn't hit when turning unless i go to a shorter tire.

    i drop the rear an inch and that has seemed to help some.

    You can get 29 x 18.5 x 15 under the fenders

    You just have to use a big hammer and lots of super glue

    Can anyone tell me if this wheel/tire combo will work?

    I have a stock '78 Mach I and am considering the following changes:

    Front: Granada 11" brake swap, 15 x 7 wheels with 4.25" backspacing (6 mm offset), 225/50R15 tires

    Rear: Stock axles redrilled to 5 x 4.5 bolt circle, Ranger drums, 15 x 8 wheels w/ 4.5" backspacing (0 offset), 255/50R15 tires

    At some point in the future I would like to lower the front end 1 1/2 - 2".

    The only modifications I want to make to create more space for the tire envelope is to roll the quarter/fender lips if necessary (no mods of control arms, etc.)

    I don't know how much offset the Granada rotors add. I've seen claims of 1/4", 1/2", 3/4", and 1".:shrug:

    I appreciate any help you can provide.

    Steve

    On my 78 Cobra I am running the 225 50 15 on the front on 15 x 8.5 rims but it had it's share of problems but have located a set of 14 x 6 5 bolt slots that will get fit with 225 or 235 60 14's after the restore, now comes the fun part the rears are on a 10 x 15 deep slot sporting 295 50 15's and yes they fit, had to build fender flares to keep it legal as I disliked the idea of mudflaps and with that setup i find it launches quite nicely

    Steve seeing how you are planning on dropping the front end down a little I would suggest running a 14 inch 60 as I had rubbing problems after I stiffened the front end up and the ride sucked, cornered like a dream due to almost no body roll but the ride was very rough, I have the granada rotors and I think a 4.25 back spacing, even running a straight line with new coils up front the tires had words with the fenders till I stiffened the front end up but then it felt as I was driving with no motor as that is how stiff it became and tight corners like in a parking lot the tires will rub on inner fender but it does look sharp
