Well i looked a bit closer at the zl1 with the wheels off. The DSSC 1le struts up front are slightly different right above where the spindle meets shown in the photos. I would assume the shock bodies are the same size or very close, and according to what i see the to get the front wheels on the zl1 you would have to cut the mounting tabs some with and angle grinder. Oddly enought the standard ss is cut more like the red mark i have made.

Cant read my photo but there is 8mm clearance on those mounting tabs and the rim rides right where its cut, so if you was going to 19s that would have to be cut down 12mm roughtly. Its seems there is only around 8-10mm between the tire and the actual shock body, i would say only running 305 on this same rim may be very close to rubbing.




As for the Rear the shock has roughly 54mm, angle looks off in photo but its around 54mm, before you would hit it, tons of room, tightly area is at full droop and the tire is about 8mm from the fender liner, i noticed behind the liner there a wire loom and then 12mm back chassis. The 1le has hardly any droop, im guessing that is how they are getting by with it. Im no sure you would ever be at full droop unless either ramping the car or jacking it up.



Problem area in rear at full droop.


The offset codes on the wheels are the same as gm.

Front 20x10 jxis20


Rear 20x11 jxis43


For giggles put a rear wheel on the front and it would take a good 30 mm spacer to make it work, here is the photo on if 30mm out it would stick out.

SORRY TO
BUT=China Die cast Wheels @ 175+mph OMG

If you know how the Chinese currently cast their materials with high impurity levels, you will be concerned.

I really hope I'm wrong on the one.

THANK YOU lmcgrew for posting/sharing this info.

I might start thinking of some NDT'ing the wheels after X-Number of Track Days as a safety measure.

China is ripping us off in trade!

Believe it or not guys not EVERYTHING that's made in China is total shit.... With the proper management, equipment and supervision even low cost workers can make decent products, otherwise big companies wouldn't outsource to China. Hell next year (for the 2019 model year) Ford is moving all of the Fiesta production to China.

I prefer American made just as much as the next guy but in most cases it's just not cost effective anymore, because us Americans demand higher pay for simple jobs, example: the rising push for $15/hr minimum wage. It's just simple economics, no matter how much we hate it.

Not defending China but it doesnt mean they are crap, there is a reason they only cost $2600 vs $5000. That Dicastal is the name of the company, doesnt mean they are cast as that company seems to do forged wheels as well.

Yup, I worked in mfg / Mexico for 15yrs...you can make the same product anywhere on the globe to customer print. The OEM sets the specs & is up to the supplier to meet or exceed those expectations.

I did wire harnesses / electronic sub-assemblies...China could usually make the same products I could for the same cost we had in materials alone. We succeeded due to logistics alone. We could support the customer by supplying parts weekly lowering their on hand inventories, where China had a 30 day boat ride & had to have massive amount of parts in the pipeline. If there was a change to print or quality problem it could shut the OEM lines down for weeks, costing way more vs a quick corrective action or print change done in days.

The product is received for production & is evaluated by QC to determine if the part is made to print / spec...it's not rocket science as outsourcing is simply supporting OEM specs.

Problem lies when they start copying OEM parts with cheaper material & manufacturing processes not to spec, but that usually happens in aftermarket applications. It is very difficult to get bad product through the stringent QC / incoming inspection processes these fortune 500 companies have in place with all the ISO / QS certifications they need to follow before it gets to the lines.

Whether they fit or not will entirely depend on the offsets of the wheels, which is why I was trying to get that info now that cars are arriving with owners. IF the front is as rumour has it (19x11 +11), which is the same as the gen 5 Z28 wheel, they will fit, albeit they will be slightly close to the strut and if you run aggressive camber you will likely need a 3mm spacer. This is the same setup I've seen on Gen 6 cars with MRC. There was NO clearance issues when running stock camber (z28 wheel in rumoured size as ZL1 1LE wheel). The rears are an unknown at the moment, but as we know there is much more strut clearance in the the rear. Your last picture showing how close the rear tire is to the fender liner is a nonissue, remember, the 1LE wheels are 19's so you will be going down a full inch in diameter (assuming that you run 30 series sidewall like the factory 1LE does).

Sounds like you were making parts for GM....

Thanks for the great detective work guys. I'm also eager to know if the ZL1 1LE offsets will work on a simple ZL1. And yes I understand the ZL1 1LE is 19" vs simple ZL1 20"

I'm hoping to put on either 295/30R19" on a 10.5" wheel OR 305/30R19" on a 11" wheel on the front of a simple ZL1. 325/30R19" on a 12" wheel on the rear of a simple ZL1.

[Stephen12ZL1]

thanks for the info...great post!

[soceur77]

are the zl1 1le wheels lighter, or with the increased depth equal out about the same as stock ZL1 wheels?

Can you check the inside stamp for the front and rear offsets, please?
