Backspacing and offset for 99 Mustang GT cobra wheels polished/painted

[1993SSP]

Anyone have the specs for the cobra wheel on the 99 Mustangs, they came in 5 spoke either polished or painted sliver. I need the backspacing and offset

 

[MikeC]

They are 17x8 with 5.75" BS, don't know offset.

I need the offset more than anything. I have the 5 lug conversion and used a 94 model rear end in my car, trying to make sure a set of wheels will work before I buy them

 

[MikeC]

They will work with the SN95 axles. Actually I think they look better with the longer SN95 axles than stock length Fox axles. They fill the wheel well out better. The M2300K Cobra brake kit recommends 17x8 wheels with 5.75 inch BS, such as any 94-04 17x8 inch Mustang wheel (Cobra and GT). FYI: The 03-04 17x9 Cobra wheels will stick out too far and hit the fender lip.

Im tryin to figure out if i will be ok with the ROH ZS 17x8.5 on my fox body with the 94 model rear end installed

 

[MikeC]

Don't know about the ROH wheels. Why are you asking about 99 Cobra wheels then?

 

[1993SSP]

I have the 99 cobra wheels, needing the offset spec so I can enter that info into a wheel offset calculator to make sure the ROH's will fit

 

[MikeC]

If you have the Cobra wheels you can measure the offset. Put a straight edge across the back of the rim from side to side. Measure down from the straight edge to the mating flange. Subtract 5.75 inch from the measurement you just got and that is the offset. If the measurement from the straight edge to the flange is larger that 5.75, its a positive offset. If it's smaller, then it's a negative offset.

Thanks, I'll get the measurement this weekend and go from there

Or just go to any website on internet and look up the offset for any FMS wheel? Tirerack, probably fordracingparts.com, etc..

Says the backspacing is 5.72. but does not give the offset

 

[Snikt89GT]

yes it does.
