Lightest k member - confused!!
I've been searching and reading for days and still don't know what's lighter pa racing or BMR. Some posts say BMR and some say pa. What is the final weights including engine stands etc?
Thank you
Thank you

If its a drag only car then by all means go for the lightest one you can find, but if you drive it on the street or do auto-x events I would look at something safer with a proven history like the UMI piece. They have a standard version and a reinforced road race version that sacrifices weight for strength and rigidity.

Add around 8 lbs due to the stock stands and your going to be about the same as the BMR with integrated stands.
PA Racing does make an LT1 k-member with integrated stands as well. Mine (CM) weighed 21.2 lbs in the box on a bathroom scale. Just give Jason a call.

Jason already confirmed I can get both power and pinto rack mounts, I'll ask him about the weights to...

I've ran Spohn and BMR full k-memeber/a-arm setups. The Spohn pieces sucked and the lower a-arms bent at the shock mounts, terrible customer service and shitty products. The BMR setup \ first sent to me was jigged wrong and had a ton of scratches on all of the pieces. They offered me 10% off or a new one if I sent it back. I told them the motor mount was half an inch off so they sent out a completely new set. I had their upper a-arms bend on me, once with stock shocks and another time with brand new coil overs. They replaced them for free.
Bottom line, don't go with anything Spohn.
Don't buy the upper a-arms from anywhere.
Make sure the new k-member comes with the proper frame bolts as some of them require shorter lengths.
See how they secure the brake lines near the a-arm mounts. (the Spohn k-members mounts for the hard lines was terrible)
I've found that many of these companies that still make products are really just going thru the motions. You need to do QC on all of these parts since most companies aren't.

BMR and the PA Racing k-member I have both have fully integrated LT1 motor mounts so you don't use the stock stuff and you save the 8 lbs. Look at the BMR k-member versus pictures of the Spohn or Racecraft and you'll see what I mean.
So in the end, going with Spohn, Racecraft, or the standard PA Racing (CM) k-member will weigh around the same as the BMR (mild steel), but Jason can build you a k-member with integrated mounts like mine which weighs less than either of those options.
Based on pictures of the UMI k-member, it looks in between in that it looks like you don't use the stock driver side stand but you still use the passenger side motor mount. But as mentioned, the UMI k-member is very stout.
I have Burkhart spindles and Strange brakes about to go on the car as well.

Jason at PA says the one with built in stands is 8-12 lbs lighter
I don't know if I can afford it now I am waiting on him for a price, I might have to sell some more stuff first before ordering. I still need wheels and tires, that's a bit more important right now then a lighter k memeber or I'll just have a lighter paper weight come spring if I buy stuff out of order
