CT4-V 4 BW Front Spoiler

[RDATLTE]

Do any of our fine members have access to the GM Parts Database? If so, does any inventory show anywhere for # 85563054? It's on back order and can't even be ordered until 12/30/25 - 01/13/26.

It looks like there are a few of the 3rd party parts sites that tap into dealer networks showing the part as available. For things that are on constraint/you know they are hard to find, I typically email/chat with their CS first to verify they have the part in stock. Sometimes they do, sometimes they don't. Given the amount of money here, I would definitely contact them first.

Wow, the price on those has really skyrocketed. This is what I purchased it for in 2023:

That has to be the black painted one and not the CF one the OP is looking for.

Thanks but, I don't see anything regarding availability on the first link and the 2nd link states Currently Unavailable.

Nope. It's the same part but the part number has changed.

MSRP is currently $3,436.34!

No luck there either.

I would image buying CF bits are like getting a BW in '22-'23; it takes a lot of work/effort to track down someone that has what you need.

 

[rubberduck]

Go to the dealer that the car was purchased from and attempt to negotiate price. That worked for me. It did take me 1 year to get the splitter for a 5BW in 2023, but my price was locked in. Keep in mind that many of the online shops add $300 for shipping and dealer does not.

I'm concerned about theirs not matching the OEM.

Thread 'Tapout Tuning CT4-V Blackwing Carbon Fiber Front Splitter'

Oct 28, 2025

Has anyone purchased Tapout's carbon fiber front splitter for the CT4-V Blackwing? If so, how did the carbon fiber match to the OEM carbon fiber?

PSA: they're currently on sale for 35% off.

I found one in stock in Ontario, CA but unfortunately, they won't ship it.

Extreme On Line Store has an aftermarket carbon fiber front splitter for the 4BW that's 1/3 of Tap Out's with free shipping. Has anyone pulled the trigger?

 

[ngoni]

Tap Out's is a better design. Not sure it's 3x the design. I went with the one Street Driven Performance sells. Likely from the same place EoS gets theirs.

Interested to see how this goes. My front splitter had a crack in it when I bought the car. I've ordered a replacement along with the IMSA decals, but they are on backorder, so I'm not sure how long I'll have to wait. Just went with my local dealership.

Interesting as I haven't even been able to place an order due to the back order. I still have 1 IMSA decal as they come in a set. If you have the part number handy for the decal, please post it.

This was all I was provided, but if this doesn’t include the part number, I could ask the parts rep for it.
