spent $10-12 and made five of my own... One for the jack and 4 for the jackstands; found I had to bolt 2 together for each one just to get some clearence and I didn't like how much I cut through the 'top' puck, so the 'bottom' puck was piece of mind.

My car doesn't move on these at all... Notched the bottoms to sit nicely on my non-flat jack stands.

Not a great pic... I could take another if anyone is curious

I've seen yours in a few other threads and do like them. I wasn't aware that you notched the bottom though for the jack stands. Do you have any photos of the bottom or of them being used on the jack stands? The notching of the bottom isn't a bad idea to use them with jack stands.

Well, my pinch weld for the rear driver side is slightly bent as well :(

Wonder if the dealership can fix it.. heat it, bend it back etc.. If not I'll take it elsewhere probably a body shop

AWESOME idea! Yes, photos of the bottom of the puck would be GREAT!

This one will work better with our cars and other sports cars. It's the same jack, just a little shorter.

I saw those but they weren't available for same day delivery and I needed them that day. 11" vs 13" wasn't a big deal for me.

I currently have mine up on 4 jack stands for the Winter. It REALLY makes me nervous, as each of the pinch welds are sitting on the metal "V" on the jack stands. I did use my ZL1Addons magnetic jack pad with my floor jack to initially lift the car in order to place the jack stands down. It worked well for me.

Having read your thread, I just ordered a set of 4 Race Ramps FlatStoppers, to start using for my Winter storage months.

Again, sorry to hear of this and will be watching this thread to see if someone can chime in and give you some recommendations to possibly repair the pinch weld.

Mike, how did you get the rear on a jack stand at the pinch weld. I thought the cross brace on verts took over that space on the rear?

Man, you guys are really overcomplicating this. I don't like using the pinch welds due to obvious reasons.

What I do is use the cross member up front with a 4x4 block of wood and the frame area behind and inboard of the front wheels.

For the back, I use a piece of wood on the rear cradle to body bushing point just inboard of the rear wheels where the rear subframe to rear cradle bushing sits.

I've lifted my car at these location points several times already with not so much as a scratch or mark done to the car. Of course, you may need some ramps in the front to raise it high enough to get the floor jack under the engine cradle with the piece of 4x4.

I've had no problems using this method on my 5th gen so the 6th gen should be very similar if not almost the same.

The 6th gen is not the same, unfortunately. The front cross-member is covered by the aluminum shear panel on SS and ZL1 models, so it's not practical to remove the aluminum shear panel each time. Inboard of the front wheels, there's a lift point that suitable for a 4pt lift, but not for jacking up one side at a time (several on the forum tried and posted pictures of damage afterwards). I'm going to have a closer look, but it appears that the pinch weld is the least risky jacking point in front (when jacking one side at at time) and is the only place recommended by GM. The rear is easy since the crossmember behind the diff can be used.

The LT models have it easier up front, since they don't have the aluminum sheer panel and the front crossmember is accessible.

im going to use 2 jacks up front to lift both sides at the same time.
