Kind of a weird question, I plan on tracking my non 1LE ZL1 @ Willow Springs etc and have been looking into getting a GM 1LE rear spoiler, if my NON 1LE zl1 doesn’t have the front canards can i still benefit from just getting the rear 1LE spoiler? And I’ve also read that the 1LE spoiler will affect top speed or straight line type racing, will I sacrifice that if going to the 1LE spoiler? Thanks for any help!

Yes. Increasing downforce lowers your top speed and acceleration.

Thank you for the response, anyone with some input on not running the front canards and using the rear 1LE spoiler? Pros or Cons?

Although the wing hurts your top speed, it should help in the turns. There aren't many tracks where the straight aways are long enough to hurt with the wing. Most tracks you aren't getting anywhere near top speed before getting to the next turn where the downforce is going to help you not break the rear loose.

Obviously without the front canards you are going to experience some lift in the front but the car is naturally front heavy with a 52% to 48% front to rear weight balance.

Only because no one else is answering... This is more of an opinion than fact or personal experience.
Depends on how fast you are going. The faster you go the more impact it will have. But it seems like a horrible idea to increase the downforce on the rear while leaving the front untouched. You are essentially putting a large amount of weight in the rear of the car and nothing in the front. The balance of your car will be thrown off and the front of your car will break lose far more easily, a very bad thing.
The faster you are going, the larger the impact you will notice. At auto x speeds you won't notice any difference. At nurburg speeds the difference will be substantial.
The stock ZLE is 54/46 and at full downforce without the canards it would change to 50/50 with just the wing... That is a really big difference. 50/50 might sound good, but the suspension isn't set up to function with maximum efficiency are those numbers.

I wouldn’t if you’re plan is to run it at Willow Springs... that track has long straights and a long sweeping radius turn (Turn 9 I believe)before it hits another straight. Speeds of 150 mph are not uncommon on Willow Springs. At 150 mph, that rear wing presses 300# of downforce on the rear end of the car. With no front splitter, cannards, and side winglets helping balance the front end with downforce, it could very well make the car unstable and definitely unbalanced when entering the fast approaching turn. That might make a trip off course very likely... GM design engineers built the front end with purpose, at great expense, in the wind tunnel. If they felt it was unnecessary , they certainly would have saved the money in development and manufacturing cost. That’s how they operate.

You can do the whole ZL1 1LE front conversion for about $800. The front spoiler, dive planes, and lower grill work together.

The normal ZL1 is fine as-is. I would track without the aero a few times and then add it all.

The other option is to make the car have Active Aero for the rear end. If you want to have the aero flatten out at top speed it's not that hard to do. It will give you back your top speed if that's a concern for you. I have been toying with the concept on paper for my other car. It would be really easy to do on the Gen 6 Camaro. You wouldn't do it with the OEM spoiler thoough you would need to use one like the GTC wing https://wildhammermotorsports.com/16...r-performance/



Small servo or pneumatic cylinder to make it work. If someone knows Raspberry Pi well it would be pretty easy to automate it based on speed. Would even function as an airbrake under hard braking.



Aeromotion makes an amazing setup. They just don't have it for our cars. Yet...



with enough interest they would make it. At the cost is about the same for their dynamic wing as it is for the OEM spoiler on sale.

Wow the S2 dynamic wing is amazing, it's a great concept for downforce on a turn and also the straight aways.

It's pretty awesome.



The snap braking is crazy too. Next level tech that's in use by the hyper-cars.



I figured out some more simple ways to make my own on paper but it's no where near as refined as they have made it.



Pressurized struts would also act as a self limiting setup. The aero would relax once certain amounts of airflow hits it and it wouldn't go over a specific amount of down force. It could be done to limit drag to no more than a few hundred lbs of down force. As speed increases the wing would flatten. As it flattens the small air struts would pressurize and create a curve of down-force. As the speed increases it would remove and de-curve what was a linear graph and make it tunable. Not sure if I am describing it correctly. I enjoy researching this stuff. I've considered making conversion kits for other companies aero setups. Variable forward spoilers are where things get sporty.

big difference for sure but definitely drags on long straightaways. The rear stability is night and day in turns. In conjunction with the front canards, it is a winning combination.

[clg82]

Great info in this thread everyone thanks for your input!!! Looks like I’ll track it as is and if i find i want more help in the corners a full upgrade to the 1LE canards and rear spoiler are in order...

[TheRealJA105]

I tracked a supercharged SS with ZLE rear wing and no canards. It was fine, check my laptimes in the laptime thread...

But if I had a ZL1 i would have definitely modded the bumper to accept the factory canards.

[Jinso]

There are plenty of modded non Camaro cars with an aftermarket wing and without canards they still saw improvements.
