Finally someone is making the Z28 splitter for the ZL1! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I am so frigin excited. Black Ops is going to be making a Z28 style splitter in Carbon that will fit the ZL1.. Can't wait...

Remember, the ZL1 was "tuned" aerodynamically with its current parts. Altering that will affect its performance and maybe not in a good way.

True. However if it is actually designed like the Z/28 splitter then it will be generating front end down force and I definitely have had a couple times where I wish the front end was more planted on the track.

Yes, but it is a balanced down force between the splitter and the spoiler. You could be changing the overall balance of the car. I don't think they actually affect anything until around 130 mph or so.

Well, I have the Z28 wing on my ZL1 and logic would tell you with the Z28 wing and Splitter the down force would be greater and that would help. BUT, lets not forget the other side of this picture. The Z28 Splitter in Carbon Fiber on the ZL1 would look SICK!!!!

True, but I am sure at some point too much down force will have a negative affect.

I respectfully have to disagree with you. But like you mentioned, non of this matters until your over 130 + MPH

Only the engineers can probably answer that question. I had a discussion with Fbodfather about it a long time ago and he said he wouldn't recommend changing anything on the car aerodynamically because it was "tuned" in wind tunnel tests. That was the reason they didn't change the front end on the 14-15s.

I've got to disagree about "not changing anything." There is plenty that can be improved upon the ZL1, especially if you're going to track it (i.e. cooling). But since we're talking about aerodynamics I will keep my opinion focused on that. I recently added the Z/28 style wickerbill to my car and it felt slightly more planted in high speed turns / chicane's. My lap times on that track came down significantly, however I would also attribute some of that to increased comfort levels on the track.

Obviously if you go changing things on the car, it is going to change the behavior of the vehicle. However if you know what you're doing you can change that behavior to better benefit the track-ability. I agree that these pieces that increase down force aren't going to be realized until you are in triple digits and/or upsetting the stability of the vehicle (i.e. hitting high speed turns, chicanes, etc).

Honestly I think having the smaller splitter is more because the ZL1 isn't as low of a production volume / niche vehicle as the Z/28, and the ZL1 is more for the "masses" so-to-speak. The ZL1 could have easily had a large splitter and been "tuned" for it. The Z/28 front splitter is so large and inconvenient, it only makes sense to have that on a race vehicle. The ZL1 is a street car with track inspiration, the Z/28 is track focused.

My opinion.

Not a fan; Thanks.

I am no engineer but I would think if you increase the down force on the rear aren't you decreasing it on the front and visa versa? I would think you would need both the splitter and spoiler to balance the car.

I would say that is a good assumption, which is why I'm somewhat interested in this. However, prior to doing the wickerbill I was having more issues with the back end in high speed turns and chicane's than I was with the front end. Ultimately I decided the back end was more of an issue.

Sven59 · 11-12-2014, 02:27 PM

That would make sense, since the idea of the wicker bill is to fine tune depending on the track you are running. It would be nice to hear from one of the GM engineers.

Subaru STis and Mitsubishi Evos have gone round and round and round with this issue, as both have huge rear wings and no front splitter to speak of (front end lift at speed). Adding a front splitter did not make the rear downforce disappear. YMMV

The ZL1 is such a heavy car to begin with. Someone care to explain to me the differences between downforce and weight as it applies to coefficients of friction at the tires in a turn? In other words, does additional downforce add to the weight problem? The car transfers its weight pretty well, but I was wondering at the science of it. Because I don't know.
