Hey everyone

I was always curious about these because it's always been a pain to jack up my CT4BW.

I ended up getting a set of Amazon for about $30 and found some longer M6 bolts in my bolt bin and managed to get these fitted without any issues.

The front spot requires a little bit of trimming to fit. Quick job with a sharp razor blade.

The rear pads really don't fit next to the "Designated" spot because of what I would assume is some rear brace. The frame rail is just as thick 6 inches closer to the front so I attached them there. No trimming required.

Overall they work. I added a crap ton of Blue Lock Tite, hopefully they don't vibrate off.

Hoping this helps everyone.

Can you link exactly what you purchased?

Thanks for posting
 
Do you have CF2 with the carbon fiber side splitters? There's a big thread about jacking these cars up, and the ZL1 style fit the CT5 but not the CT4's with the CF splitters.

Hey there. I do have the CF2 splitters from th factory.

As you can see in the photos, they fit. No issues here.

Thanks! What length M6 bolts did you use by chance? Gonna order everything right now lol.
 
I followed the larger thread (here) and ended up ordering a few things to support easier lifting especially when using QuickJacks. I was hoping ZL1 AddOns would get the memo and machine a set for 4BWs but they don't seem to be doing that, so this might be next best thing.

Two questions:
  1. Have you tried lifting with QuickJacks? Does your modified rear pad placement line up with them?
  2. Where did you place a jack and jack stand(s) to support the car while you were installing these?

1. I don't have a quickjack, sorry so I can't answer that question.

2. I ended up using ramps to install the pads. I jacked up one side at a time and placed ramps underneath the front and rear wheels to keep the car supported. I jacked the car up using the front pinch weld with a low profile jack and a hockey puck.

Honestly that was my solution to jack up the car for a while, but since I'm planning on getting a set of Apex wheels in the future, I needed a no brainer solution so that the tire shop goons know where to jack up my car without damaging anything.

Thanks for following up!

Totally hear ya... I was changing wheels on my Mustang for track duty for 5 weekends a year. That's 10x jacking the car up just to support those changes, and many more for maintenance upgrades. I got really good at it, and the Mustang made it so easy. Jackpad in the middle, plenty of room front and rear for jack stands.
 
Interesting approach. Thanks for the pictures! I have a few questions:
1. Do the top of the blocks rest against the car, or is there a gap on top? Looks like there is a small gap.
2. If there is a gap, how do you keep the load from transferring from the block to the bolt to the hole in the pinch weld? Do you remove the bolts prior to jacking?

I feel like the blocks rest on both the top and the pinch weld. I don't recall there being a gap on the frame of the car. I would feel the top of the blocks drag along the car.

I lined up the blocks on the pinchweld and tightened the bolts just enough so they wouldn't slide off. I then used my jack on the block to unload the suspension and apply weight only the block. I then cranked them down with my ratchet.

I jack the car up with the bolts in place. I did a trial lift on every corner with no issues.
 
I knocked this out yesterday and had great results. My Lowes didn't have the correct length M6x1.0 so I had to go with 30mm, which is fine.

I selected almost the exact same positions as OP, with a few cm further rearward for the back placements. All 4 corners required trimming of rocker plastic but it took just a minute or two with a sharp utility knife.

The front position has an existing cutout of the body colored plastic, but you'll need to trim the black plastic that's 'higher' up towards the floor. See PIc 4.

The rear position will require you to trim the body colored plastic. I went a few cm further rearward for these than OP, so I could make use of an existing cut where a tab was. See Pic 1&2.

The best part for me is that these positions are now perfect for use with my QuickJack 5000SLX and the tall lifting blocks that came with them. I'm less sure at this point how I'll lift the car with floor jack and jack stands with these pad positionings, but I don't anticipate needing to do that very often.

Really appreciate this thread. I finally got a weekend to tackle this with some Race Ramps. Those with CF1/2, the ramps did rub on the front splitter a little, luckily mine is PPF'd. Ended up using some towels right before the lip touched the ramp on the way down. Luckily not too much dmg to the PPF underneath and at the very tip on the front.

I only did the fronts. Trimmed in the same area, but ended up going all the way to the outside of the black trim. Also put the front ones as close to the front as possible to match up where the usual lift point is. I figure as long as you're in the general area, it's fine.

I'll tackle the rears and an oil change another weekend.

I bought these months ago and I need to put them on. If it wasnt so damn hot as hades in my damn garage, I would have done these already.

I did mine outside in the Texas heat lol. You got it big dawg.

Dumb question, but is this not the purpose of the jack pads? To lift them with a jack at that point?

Yeah, i worded that poorly. I meant to say that it wasn't immediately obvious where the jack stand would go if you used the lifting block for the jack. Or where the jack would go if you intended to use the lifting block for a jack stand.

I have since figured it out it works great for both the jackstands and quickjack application.
