Any idea why it can't be used on a car with a lift?
The Eibach & aFe swaybars fit all C8 Stingray (coupe & HTC, base & Z51) models. If they don't have your exact model/combo listed, its because they personally haven't test-fit them. I'd assume they'll fit the Z06 and eRay as well, but cannot confirm that yet.

You are probably correct on the Z06 and ERay, but without knowing the rates on the Z06 and ERay, you really don't know what the bars will do for you. How they might affect the front/rear balance. Being somewhat adjustable will help.

That is correct. Now we wait for Eibach and/or aFe to do that heavy lifting for us
Do know what brand end links? Going out today to finally measure and possibly just order my own hardware. Eibach still claims they don’t have any for the C8. Which is odd because their website says you can custom order any sizes. The guy on the phone really didn’t seem like he was knowledgeable. Seems he was a new employee.
No I do not know the brand. They came with the sway bar
Here are aFe's recommended settings to start working from:
Suggested Initial Settings for Street: Front: Position #3 Full Stiff (Hole furthest from end) Rear: Position #1 Full Soft (Hole closest to the end)
I have had great luck on track with AFE rear bar at full soft and the front bar at middle hole. This puts rear 100% stiffer than stock Z51 and the front 75% stiffer than stock Z51 so reduces the slight tendency of snap understeer at the limit. Car is very balanced for me at these settings. I am also running double adjustable shocks with stiffer springs so your results may vary.
I will try. The motor is getting dropped in a few weeks for it's build. After that alignment, corner balance, touch up alignment test and tune. Might be testing different sway bars also. So with all that work done not sure it will be a felt changed for myself. My setup has a lot preload and can be seen visually when standing back not to mention just removing the OEM endlinks is very tight. I do have two turns in mind where i felt there may be something going on. But could be my entry. So much to consider. Come 24 I will be getting driver mods...... coaching.
And this eliminates another rubber bushing.

Getting to this thread after my weekend at COTA. WOW! These cars need sway bars. (Z51 for me). The esses and long carousel exacerbated the weakness of the Z51. I couldn’t believe it. Sluggish and slowest of any car I have had at COTA…..and I have done everything just shy of most aggressive track alignment.
Met a guy who had the AFE sways. Said it changed the car drastically. Sign me up!
As for the Z06…..the Z07 I have access too is much stiffer. That’s probably another story. I sure hope GM didn’t leave any room to improve on the track model.
Eibachs front endlinks off the shelf won’t work with AFE bars. Due to the thickness of the mounting ends and slight offset. Will update when I get it figured out and finished. The angle of the mounting hole on the lower control arm doesn’t help much. Pretty much just need 1 10mm longer spacer on each end of each endlink to align with no bind. Found this by stacking washers. I couldn’t adjust or especially tighten down without damage. Plus 25mm longer bolts. The rears were perfect.
Working with Eibach on it. Doesn’t surprise myself They built them around their bars.

super useful info, I may buy rears now and wait to see what they come up with for fronts.

Sometimes you have to modify aftermarket or mismatch brands.
Also I feel the heim joint on the control arm side could be bigger for more range.That would solve it really. The joint doesn’t have the same range of motion as the OEM joint.
The guy at Eibach said the link will bind at full droop on the lower joint. Understandably. But a taller joint would avoid that too. Long as it’s centered under load is perfect.

I ended up needing a total of 20mm spacer to get this more even. Eibach knows others have longer spacer especially on aftermarket bars. Being Eibach develops their own bars and endlinks, you won’t need but a 5-10mm spacer/ ear that comes with the kit.
You will see in the pics how my AFE bar ends are formed more center of the bar with a thicker end. OEM and Eibach ends are flatter and more outward. The OEM endlinks have a larger range in motion than the smaller but a lot stronger Eibach hiem joint.
I was going to go with one smaller spacer on each end of the endlink. Either way I would need longer bolts. Add that to the equation you wouldn’t be able to feed the bolt in with the hardware due to the coilover tower and I didn’t want to stack washers ultimately. So as I said I needed a 20 mm spacer total. Ended up with a SS 3/4 (and 19mm) spacer and a 1” longer bolt.
It’s great now. No bind under full droop or compression. A lot stronger than OEM. Eibach said you would have a little bind under full droop with the standard kit. It is a small compressed area.
When first attempted. Full bind and won’t extend further.
I've been looking at sway bars a bit. I know there has been some discussion in this thread regarding Z06 sway bar rates. Article implies Z06 has smaller bars the Z51. Seems I saw a video where a GM engineer said the same thing. It'd be interesting to verify.
The engineers say that the tauter springing keeps the edges of the ultra-wide tires more upright in cornering and also reduces body roll enough that the Z06 can get by with slightly smaller anti-roll bars than the C8 Z51.
