i bought the car with everything on it already and i can see it has bbk lowering springs on it...but i want to change the wheels...it has 17" cobras with 245/40/17s on both front and back and on full lock the fronts rub the lowers c/arms a little bit. i want to put 17x9 SC replicas on the front and 17x10 on the rear if possible. how do i know if they will fit my particular setup? also my exhaust dumps b4 the rear axle so its not in the way. thanks

I'm not sure how bad the fronts are going to rub, but you can clear a 17x10 in the rear. You will have to massage the inner fender with a big hammer. How much so depends on how big of a tire you plan on running.

i heard i have to remove the quad shocks and put in an aftermarket a arm or something? i just see a regular shock and springs? perhaps they removed them when the car was lowered? this is my first mustang so sorry for all the noob questions.

10 inch wide rears are more headaches than they are worth. Ya, it can be done, but there really isn't a good reason to make things so close, it's not the rim that doesn't fit, it's the tire.
And you can put the the max size tire the car can fit, on a 9 inch rim.

you can keep the 245's if you want. and go as wide as a 275. worse case is you buy 2 new rear tires and have a pair of 245's for a rainy day ( flat tire or whatever )

If you want to run a 315 on a 10in wheel. You are going to have to beat the inner fender.... "a lot" and will also have to roll the lip on the outer fender.

For what its worth - I run 275/40R17 and i rolled my fender using a fender roller. I rented it for $50 and it got the job done. I also run Steeda springs and Tockico shocks- no problems with that set up. You also need to consider off set and brand of tire. Some tire companies run wider/thinner than others. GL

Im not familiar with stock Mustang susp but Ive got 295's on a 10" Draglite and from what I can see it doesnt look like anything was beat or massaged.

As for whats different about the susp on my car vs stock I have no idea because I dont know what Im looking at lol....

it looks like the biggest you can run with little problems 275/40R17? because i was going to try and run 285/40R17 on my 88 Vert with stock suspension......maybe i should rethink that and just go with 275??

I run a 275 55 18 bfg drag radial, and they use up pretty much all available space, and hard cornering makes them rub.
