Default A question about Shelby Series One wheels.

Are there new sets out there and what does a set go for and is the offset dead on for a ZR-1?

To my knowledge these wheels are long out of production but some folks are likely sitting on sets that have never been used. Basically you have to watch ebay and various forum "for sale" sections.

The offsets are close but not dead on. If you mount them as is they will stick out past the fenders a little bit. The other option is too reverse the centers and mount them with 1/4in spacers for a more tucked in look as in the photo below - note: doing so will require longer wheel studs.

Are the centers cast and if so is there enough material to machine of a touch?There alot of wheel on the market just are just too busy,got too much crap goin on but I like these.Kickin myself for no buying a set when they were dirt cheap.These wheels look just as good as some of the $5000 wheels some companies have on the market today.

Not sure if there is enough but I guess it depends how much you want to shave off

Here is what I had saved from a post somewhere on the Net, I think it was CF, but could have been here

Well I did the test fit and here are the results:

Fronts (measured from brake rotor face to outside lip of wheel)
Stock = 9cm
Shelby = 10cm
Diff = +10mm

Rear (measured same)
Stock = 14cm
Shelby = 15.9cm
Diff = +19mm

Wheels stick out too far so I tried a modification which LocoBob suggested.

I put the center sections on the outside instead of the inside of the wheel joining surface. Center section fits like a glove on either side...

Here are the results:

Fronts (measured from brake rotor face to outside lip of wheel)
Stock = 9cm
Shelby w/mod = 9.3cm
Diff = +3mm

Rear (measured same)
Stock = 14cm
Shelby w/mod = 13.5cm
Diff = -5mm

I added my 1/4 inch spacer to the back:
Stock = 14cm
Shelby w/mod + 1/4 inch spacer = 14.4cm
Diff = +4mm

I may be mistaken, but I believe the centers are magnesium.

no I don't think they are. they are quite heavy for magnesium I think

pretty sure they are aluminum, but I could be wrong

It was something I'd read about the Series 1. But it could have been some preliminary specs or something, or just a good ol' lie from Carroll...

Hell, old Texas chicken ranchers like Carroll never really lie, they're just stretching the truth a little to make their stories easier to listen to.
