    OEM 4BW Graphite replacement wheel - part numbers?

    And the TPMS nuts ($5 ea, 84413358 for TPMS 84977020, paid $132 for 4) . There could be third party alternatives to the TPMS others have mentioned.

    OEM 4BW Graphite replacement wheel - part numbers?

    Your numbers match my notes from last Fall when I was trying to order some. Unless they changed since then, they should all be correct, polished and satin.

    CT4-V FLOOR JACK LIFT GUIDE - 4BW

    Hoping not to create another one of those jacking debates, but the service manual does not list the pinch weld to be used for the rear on the 4BW. I've just used my jack with a large rubber cover to contact the suspension bracket with no problems.

    Help me fix my aftermarket carbon spoiler

    I checked that number 85561509 on a couple sites and it successfully added to the cart. Do they take the order but then respond it isn't available? gmpartswarehouse warns there is a 7-day factory lead time.

    Apex Wheels for CT4-V Blackwing

    No, the holes are larger than OEM so the clips won't grip. The overall diameter of the cap is about the same though. I fabricated what are essentially adapters as described here: Questions from an overthinking/over prepared engineer impatiently waiting his Ct4-V B.W.

    Help me fix my aftermarket carbon spoiler

    At one time Tapout listed reproductions of the support brackets but I don't see them listed anymore. But really the price was pretty close to the factory bumper cover so that should still be a viable option if you have the means to get that huge box home. Then you either keep the cover as a...

    Help me fix my aftermarket carbon spoiler

    I installed the Tapout rear spoiler on my car over a year ago and I haven't seen any evidence of leakage. But, it did concern me because the standard OEM spoiler had that adhesive bond along the front edge, and the rear gasket completely encircled the screws and holes through the deck lid. I...

    Carbon Fibre parts.

    gmpartswarehouse.com lists it, but says it's a 7 day factory wait. Pretty pricey even discounted, and shipping across the US will likely be a killer too. You have a typo on the second part number. Image is from Cadillac.com - parts and msrp is $2597.42 GMpartsgiant and GMpartsdirect also popped...

    Apex Wheels for CT4-V Blackwing

    I'm happy with the satin black. I also considered the anthracite but thought it might be too close to the Shadow Metallic color and wanted some contrast, plus it matched the black trim. And we have bl4ck_wng with Shadow Metallic with silver for the trifecta.

    Manual Transmission in cold temps

    Maybe someone attending Spring Mountain soon can ask them what they are using. Similar environment to Phoenix, but maybe a little different for those of us in winter states, and not tracking 100% of the time.

    What did you do to your Blackwing today?

    It's from the recommended list, but I kept the stock rim width which gives offsets 30 front and 35 rear. The front is almost identical (28 stock) but the rear pushes out about 1/2 inch. Essentially the sidewall now protrudes from the fender. Probably messes up the aerodynamics and it's going to...

    What are the differences between the 4BW Carbon Fiber rear wings?

    It is a PITA to remove. there are other threads discussing it. If you look at mine closely you'll see the effect of teh sticky tape. Use fishing line, don't pry EVER, and good luck with that outer stud that slides into a clip that doesn't release and impossible to get to. Here are some other...
