I have a '94 GT with a Maximum Motorsports K member on it.  This kit moves the wheels forward towards the bumper 3/4".  In addition, I have upgraded the front and rear brakes to Cobra from a '95 donor car.  Our slicks on Weld wheels no longer fit the back because of the brakes.  So I am looking for a nice set of wheels that will work in the front and allow for a 10.5" wheel in the back for some big tires.  Help!  I currently have the FRPP '98 style Cobra wheel on the car. From all my research it seems I need Cobra style wheels to clear the front brakes.  I need to maintain the same final diameter (currently use 255/45) to clear the bumper, and I don't want them to protrude from the wheel wells when looking at the car from the front or back.  And I need a 10.5" wide wheel in the back that will clear the brakes ther (I don't think this is hard to do).  I think my choices must be limited.  Can anyone make a recommendation? 

You can use a 15" wheel in the back with the cobra brakes.  You might have to do a little clearancing on the caliper or run a small spacer but it will work.  If you run a spacer make sure to use an aftermarket set of hardened studs like the MOR-46180 which is a safety upgrade anyway if you are running slicks. The fronts are a different story.  Yes you have to run a special wheel to clear the front brakes.  The most popular 2 right now are the Bogart wheels and the Billet Specialties Street lites.  These are pretty expensive though.  You can usually find used sets with tires for in the $1,000-$1,250 range if you hunt for them.  Another option is to find some of the ol Weld XP wheels that are the 17 in Diameter. Sometimes you can find those as well.
