Jacking up your Blackwing

[CT4-Villain]

Don't understand the fuss. Manufacturers have been using pinch weld locations for jack points for a very long time.

Have you tried jacking up a car on a vertical pinch weld ? Metal bending and distorting under the weight of the car. This is the only vehicle I've had with this dumb design.

Yes, all my recent cars and no problems, ever.

My Mazdas all had them and jacking up the car with them using a normal jack caused them to bend and crack the paint off and eventually rust when I lived in Ohio.
My Audi also has them, so I bought slotted pads for my jacks, and the pinch weld holders for my jack stands, but the rubber holders still rubbed the paint off the pinch welds. Thankfully, rust is not an issue in Texas.
I would love to know the secret to having no problems ever with pinch welds.

I use a floor jack with slotted jack pads like ZL1 addons sells or similar. No issues. Not worried about paint on the pinch welds. They are barely painted anyway.

ZL1 addons said their ct5 jack lift pads work on the ct4s. I was surprised by this, but also not surprised. I'm more surprised they wouldn't list them on their site as working with ct4s

Cadillac 20-24 CT5 & CT5-V Stealth Lift Pads

The original bolt-on lift points made in the USA for the 2020-2024 Cadillac CT5 & CT5-V. Machined from American billet aluminum and designed to be left on the car. The stealth design also incorporates weight savings and a custom design to catch the attention of the mechanic or shop preparing to...

Did you cut out the plastic from the rocker like some owners on here have done, or did you just let the pad push on the plastic?

There is no real interference on my 5V non BW.

Well the secret to having no problems with a dumb design is to have a better design, the manufacturer should be the one to fix that, not the consumer.

You shouldn't have to modify the plastic underneath a sixty thousand dollar car so you don't damage it while doing something as simple as jacking up the vehicle. Maybe GM could hire a competent engineer to correct this ? Just a thought.

It's a user issue, not an engineering issue. I was thinking about this thread a week ago when I swapped to my winter wheels with nothing but a harbor freight jack and a regular slotted pad. I stand by my comment from two years ago:

I honestly didn't think it was that complicated, at least for a 4BW. I used a regular grooved hockey puck pad when I swapped my wheels and had no issues. I fit the groove on the rear chassis brace, and I used it as a regular pad on the front flat. This thread had me worried I missed something, but I really think some of you are overthinking it. Just avoid the carbon and you'll be fine.

I put the ZL1 Jack pads on my 4BW (link below). I had to cut a little of the plastic, but it wasn't a big deal.

I'm not concerned about myself jacking up the car to do work on it. I take the time to do things carefully. My concern is more with tire shops, etc where my trust that someone will take the adequate care is lacking. By having some bright red block attached to the car I am much more relaxed about bad things not happening.

I've had dealerships crank down on my jeep's airbox cracking it. That is someone I would expect to know not to go full send on an impact or powered ratchet. While there are plenty of good techs are discount tire, I know there are inexperienced/careless ones too.
