C7 zr1 big rear spoiler removal/delete
 

Hello all. I am about to remove the BIG-BIG OEM rear spoiler off a 2019 ZR1 - all the OEM parts will be bubble wrapped and put into storage - HA - or - (probably more likely) mounted on the office wall as some 'WALL ART' - HA. Where the stanchions where mounted, once they are removed, there will be two rectangular holes in the horizontal surface of the third brake light lip. Has anyone seen a readymade plug that will fit into those holes?

My other thought is to scan the area of the holes in the OEM ZR1 third brake light lip and 3D print a couple of plastic plugs. The top surface of the plug would be slightly larger than the hole, and with rounded edges (the photo is a 'rough' example of the type of plug I am envisaging), and then prep and paint the two plugs and set them in place with silicone. Yes - slightly visible - as the two white painted plugs against the white OEM third brake light lip will sit slightly proud (but with the rounded edges to help blend in a bit) - HA - but still somewhat less visible that the BIG spoiler sticking up at the rear.

My final thought (HA - so far) - is to purchase a new OEM ZR1 third brake light lip - then have the stanchion holes properly plastic welded - then with minimal filler - prep and paint the replacement ZR1 third brake light lip in white to match the body, and this way we also have the original OEM ZR1 third brake light lip with the stanchion holes carefully wrapped in bubble wrap and in storage if the next owner in '50-years' time wants to revert back to the BIG spoiler - HA.

Has anyone undertaken a ZR1 rear spoiler delete - and still left the ZR1 OEM third brake light lip?

Thanks.

IDEA EXAMPLE ONLY

Can’t say I have ever heard of anyone wanting to de-wing a ZR1. So you’d probably be the first to have a need for such plugs.

Are you going to remove the front splitter as well? If not…then in before the aero police chime in and say that you’re going to make your car dangerously unstable by altering the downforce balance.

If it were me and if I couldn't live with the BAW, I would just locate a low wing off a non-ZTK car and go that route. The back end will be a lot less pronounced and the entire process will be a heck of a lot easier.. Just my opinion. Good luck with it. :thumbs:

That wing is part of the ZR1 ZTK mystique but to each his own.

As you noted, you could use rectangular plugs painted body color but if you really don’t want the high wing your best bet is to replace the little spoiler with the third brake light. You will need to make the plugs excessively tall and they will look ugly.

Notice how the wing brackets sit proud of the smaller lip. Your plugs will look bad as they will stick up a bit.

You should replace the small spoiler with the built in brake light to do it correctly.

I don't have a solution for you but I thought I would share this picture. My wing was removed for PPF and this is one of the pictures I took, enlarged to show the mounting location. I didn't look at them too closely but I remember that there were plates that were close to flush with the surface. I thought I remembered them having 4 threaded holes. They are covered with PPF in this picture. The wing is back on now so I can't examine it any closer. Hope this helps.

You're gonna remove the rear wing all together?

Just don't drive into a turn going fast.

Interested in selling the wing?

Blasphemy.

Thanks - that is what it will look like with the wing off - I will probably have to remove the inner mounts as well. Thanks

I think I am going to get another OEM third brake light lip and plastic weld the holes up - then prep and paint it white (after removing the inner mount plates - thanks to pictures from George_L. I will post up pictures when doing//done. Thanks.

Yes - as you mention - the plugs will probably look 'FUGLY' (HA - it was just an 'easy way out' option that I thought of 'on the spot') - hence I am going to go down the route of getting another OEM third brake light lip and plastic welding - prep and paint it white. George_L's pictures did the 'trick' for me. Thanks.

Selling it - sorry - no - it will probably be mounted up on the shed wall so we can all have a laugh at it - HA. As mentioned - this is a everyday road car and it will never see the track. Just like a badly damaged 69 ZL1 Camaro project we have and that will get finished one day (HA - hopefully) - the original parts were long ago used in other race cars and I have no intention of piecing together a so-called 'numbers matching car' - it is a 'bitza' - albeit with some rather rare VIN - it has a late model circa 650 HP BIG BLOCK engine running on G70 15 redline COKER//FIRESTONE bias look radials - HA - totally inadequate for the HP. But just like some of my motorcycles with high bars - no mufflers - etc etc - they are 'form over function' builds. One has a circa 160 HP V-twin engine - HA - with a 2.75 x 21 on the front - it will never be a 'knee dragger' - it is what it is - 'ART ON WHEELS' that I enjoy building and making NOISE with - HA - and tyre smoke. Thanks.

650-hp BBC in a '69 ZL1 and a 160-hp H-D?!

Ok. I admit. You're way more bitchin' than me.

If you change your mind, I'd still buy that wing.

I think this thread is a "simon says" thing Hib............for a sentence to count, it has to end with a HA!?!?!

That made me HA, and shoot milk out of my nose HA HA

Now off to bead, tomorrow morning is a scheduled colonoscopy...........which is a far more appealing prospect than reading another one of your replies HA

Seems like you have all the answers, why do you bother asking the gold chain crowd for an opinion, Huh?

Hmm I’ve always wondered what Asperger’s Syndrome looked like if was in written form. I think I may have finally spotted it.

OP, this one has gone off the rails it seems. Can’t believe you’ve been on this forum for 15 years with barely a couple dozen posts only recently. Might be time to go back to lurking only.

I love my BAW❤️

Why not sell it and buy a Z06, I will trade you.....

Anyone know the part number for the third brake light cap? Will have a "big wang" but it will come out the back of the bumper. Could easily fill in the squares.

This thread should be deleted. :hide:
