Trying to figure out what wheels and tires to buy and people keep referring to fox width vs. sn95 width. What's the difference.
I think Coupe guys prefer the longer SN95 axles, other than that I think the kit is designed around Fox width axles and that makes wheel and tire selection simpler. No drawbacks that I can think of other than the actual donor type was 4 lug.Originally posted by Captain Gourley:
Any drawbacks to the Fox?
What are folks using for IRS?
Not necessarily, although some do in order to get more 'dish' in the wheel. There are a few wheel and tire combinations that will work OK without narrowing or changing axles, but you usually have to make some compromises to do it. Limited dish in the wheel itself, limited tire size (315's are a real challenge although some have managed it), and limited wheel choices are some of the reasons why most choose to swap for aftermarket 5-lug Fox width axles.Originally posted by Captain Gourley:
So you had to shorten the SN95 to make it fit to the frame and body width?
I guess you could add that SN95 refers to both 94-98 era Mustangs (3/4" per side wider than Fox width) and 99-up which is wider still. While I think the early SN95 style can be converted to Fox width by swapping axles and caliper/axle brackets, the later models cannot and require narrowing or a custom fit wheel.Originally posted by Stinson Pilot:
...SN95 width- widest of the three
True, completely different setup but the width is the same as SN95 and uses the same wheel offset.Originally posted by KC Wildcat:
Capt. IRS is completely different (axles called half shafts) They start with T-bird rear end.
