Here is a 2ss with Z/28 rims on the front.

That's why it needs the ZL1 ~13mm wider front fenders...won't take it all the poke away...

Heck, even with that, look at the outward poke of the fronts with the ZL1 fenders!

Here's what I could take in terms of pictures.

Thank you Mr. Wyndham!

SuperAlloy is a very good manufacturer.

Correct - why I did not buy a set a bit ago for my 1LE since the ZL1 1LE's are going to stick out as bad. I'll go with them if I want OEM 19's to get the wider rears and do the ZL1 front fenders to lessen the visual poke.

Those will be sub-assembly PN's in the pics, which I do know we all appreciate. I show PN 84328494 for the rear and '93 for the front. Is that what you ordered under? Thanks.

Just an FYI, the ZL1 fenders will not fit a regular SS without the addition of the hood and front bumper.

Not trying to start an argument, but, how do you know for sure? From what I have looked into, you also need the wheel liners and there is a bit of difference in the attachment scheme to the fascia-to-fender.

I'll be glad to be the guinea pig. I've got access to a fender. Figured I'd pull the fascia and fender off and try one of these days.

seanblurr · 07-11-2017, 06:44 PM

If you've got access to a fender, please try it! There was a long debate about this in the 1LE section I believe and from what I remember, the answer was determined by a comment by Al O and differing part numbers between hoods.

Just to add to the searchable database...

So I was lucky enough to be able to try a set of ZL1 1LE wheels on my SS 1LE tonight to test the fitment. A few people, including myself, were very interested to find out the specs of these wheels to determine if they would fit cars with mag ride, well, we know the answer now.

The answer is two fold, and not quite as straight forward as you may think. If you are running aggressive front camber (i.e. anything more than factory) they WILL NOT fit without a spacer. I say again, they DO NOT fit if you have an aggressive front alignment without the use of a 5mm spacer. I currently have -2.6* of camber and the wheels would not bolt up. I had a 3mm spacer laying around and it allowed me to fully bolt up the wheels, however, the lip of the rim just ever so slightly rubbed the strut. I made a u-turn in the street and the metal to metal rub was very noticeable during the turn, fine when driving straight. So what does this mean?

The answer is that if you do not track your car and you maintain the factory alignment specs, these wheels will clear just fine. If you run any added negative camber to the front, you will need a spacer.

For clarification the wheel specs are:
19x11 et11
19x12 et41

As these share the same front wheel specs as the Z28 wheels, which we have seen before, just like those they poke out quite a bit on the front. Add an extra 2mm from what you see in the pictures below to imagine how it would look with a 5mm spacer. Personally , if I were going to run these they would be a track only wheel and the poke wouldn't matter. I'd be hesitant to run these as a street wheel though, as you will get quite a bit of road grime being thrown at the paint.

One solution is the addition of the C7 Z06 fender flare like a fellow member did on his SS 1LE, this would nearly cover the poke at the top of the wheel. Another, more expensive option would be to try to fit the wider ZL1 fenders. Of course, this isn't an issue if you already have a ZL1. We already know how these wheels will look on a ZL1... *cough* ZL1 1LE... *cough*. However , for you ZL1 owners keep in mind that we do share the same mag ride struts, so you too will need a 5mm spacer, thus it will probably poke a tad on your cars as well.

To reiterate, below is an SS 1LE with -2.6* F camber and a 3mm spacer.

Hey Sean, thanks for taking the time to do this research and posting the pics. A couple of questions:

1/ Is there not an aftermarket top strut mount available that would all camber to be adjusted up top rather than at the bottom attachment points ?

2/ Do you think there would still be poke on a ZL1 ?
