The question is how much these matter in the real world; they don't seem to be a big deal at ZL1 power levels but as power is increased, they will support more.

pretty much this -- lets just appreciate both for what they are and leave it at that. I've never seen a grand sport owner pretend they have a z06

So it's different. The above you mentioned are subtle changes but they all are diff. ECU tune, exhaust tune, gearing, brakes, brake lines (?) i've heard are diff but can't confirm, fuel lines, forged internals, diff eLSD and suspension set ups. I believe the 1le does have a HPFP from factory but all other fuel components are inferior.

I do believe the fenders are different both front and rear between the ss platform and zl1.

Of course things like the heat exchangers and all components that goes into the LT4 itself are massively different but for this comparison I guess we are ignoring the engine. The overall engineering that went into the two cars are vastly different to make the components work.

And as above said, the LT1 platform requires way more up front $ to change out inferior parts to make big power where as the LT4 does not.


With all that being said; both are great cars. Not trying to be a hater but they are 2 diff cars for a reason

Yes the engine is different and so should be the fueling as the LT4 needs more fuel.

The eLSD is the exact same as well as the suspension. Only difference, like I said, with the suspension is its tuned for the lesser weight of the SS.

Cooling is slightly different as you don't need to cool the supercharger.

It's still a very track worthy car and does handle fairly close and maybe slightly better than the ZL1. Less weight and not as much weight on the front helps.

There wasn't that much more engineering that went into the SS1LE. They just took the ZL1 items, fitted them and tuned them for the SS. Whereas the ZL1 they had to design a different car compared to the SS in order to fit the more coolers, engine, eLSD, etc then tune the TCM, PTM, ECU, etc for the ZL1 so they work to how they wanted.

If someone wants a auto x or small road course car then get the SS1LE. If someone wants a car for bigger road course then get the ZL1/ZL1 1LE.

yes for sure, minor differences between the two but nonetheless still different.

but it's just weird (and impossible) to compare two cars and be like "if we take out the engine, they're the exact same" is all i am saying.

just appreciate them for what they are -- both great cars for diff purposes and diff strokes for diff folks.

same goes for all the 330m/440m cars, they aren't claiming their car is basically an m3 or m4, like its a non-existent thing

From what I understand the major differences in the cars is the different engines and the specific requirements of the two engines, the exterior being slightly different and the the way the interior is trimmed out. The LT4 requires more cooling and more fuel than the LT1 so most of those differences are related solely to the requirements of the different engines. And of course the LT4 is heavier than the LT1 due to the supercharger and related plumbing. So it needs slightly larger brakes and suspension calibrations.

As several have already said, both are great cars. The way I look at it the 1LE benefits from the trickle down of both parts and engineering from the ZL1.

saying the ss 1le is the zl1 without an lt4 is a pretty insane claim tbh

I merely pointed out similarities when it came to the suspension and powertrain, minus the engine........................."Powertrain and suspension wise, the SS 1LE is essentially a ZL1 without the LT4." Essentially, not exactly. The OP's original question:

"SS 1LE vs. ZL1 suspension/brakes, etc
Other than the engine is there a difference in the track performance part? They seem to both come with the same tires, brakes, seats, etc."


I was keeping the focus of the OP's original question. Then it was taken beyond that. Nobody is pretending their SS 1LE is a ZL1, that's utterly ridiculous.

Shared RPO codes: NV9 steering, NPP exhaust, KNR rear axle cooling, FE4 suspension, F55 MagRide, G96 eLSD, KDI trans cooling, GT4 3.73 axle (6 speed), R0G same tires, the wheel specs are the same, KC4 eingine oil cooling. All the same. Sure, there's cal and spring rate differences. The 6 speed has the same RPO but there's another RPO that calls out its different gear ratios. I also called out the (potential) brakes differences. In the end, with the essence of track performance, there are shared components other than the biggest difference, the LT4. Take the LT4 out of the ZL1, and it loses its soul, those other mentioned differences are meaningless.

you can't feasibly speak about a cars powertrain and then say "not including the engine" lmao wtf. anyway i digress. both good cars one's just better

[cdb95z28]

How did we get from an "other than engine........" discussion to "one's just better"? lol, wtf I guess we are stroking egos now.

When it comes down to it, at the road course, the ZL1 only has an advantage from center of the corner out to down the straights. I'll say it again:Since the OP asked about non-engine track component differences that engine advantage is a moot point to the discussion

Talk of different half shafts, prop shaft, eLSD tunes, ECU tune, exhaust tune, gearing, brakes, brake lines (?), fuel lines, forged internals, blah, blah, blah are all inconsequential to the original discussion.
