What K-Member to use
So far, I think it's give and take.
The BMR is heavier, but fitment is great and its strong.
The PA is a hair lighter, but fitment seems to suck and I'm not sure it can hold up to road racing...
The UMI is supposed to be kind of heavy, also, but definitely strong enough and I've heard good fitment quality.
I only have personal experience with the BMR, but don't be fooled by those crazy weight savings numbers...they're a "little" exaggerated.

Hello Members,
We also offer a very nice K-member set-up. I will agree it is not the lightest one on the market however during the build and design lightest as not our goal. We designed a item that is considered "multi" use, we recommend it for both drag racing and street use including daily driven vehicles. We also offer a step up for road race applications where additional pressure is applied to the front end.
If anyone has any questions regarding our set-up please feel free to contact us. We currently have this item with built in motor mount stands for the LT1 and LS1 or for $50 less we have them with no motor mounts to be used with motor plates.
For additional pictures please visit out site.
Thank you!

What does your LT1 K-member look like? This picture looks like it has mounts for a LS1, and I believe you have these same pictures listed under the LT1 item description on your site.
The only difference is the motor mounts... the rest of the K-member is the same. So we do use some of the same pictures but the main picture in the above link is a LT1 specific K-member.
Hope that helps!

Mildsteel vs Moly John, it all depends on what thickness your comparing. I think Mildsteel is better for all out street use. I tend to lean towards the moly for limited street use and all out racing.
I have the PA Racing K member upper & lower control arms... The fit was perfect and i daily drive the car in the nice weather ... I have 5k miles on the complete set up so far no probelms just came back from the Maryland car cruise in Oct i drove the car up & back its a TRUE STREET CAR 
Ok, ic. Per your description this K-member is supposed to eliminate the cast iron engine mounts. This K-member would eliminate one of them, but the cast iron mount that bolts to the block on the passanger side would still be used with your K-member. I realy want to get rid of both of the cast iron mounts.
Let me know if I can help anymore. Thanks!
Ryan
The factory LT1 K-member only has ONE cast iron motor mount stand. The passenger side motor mount bolts directly to the K-member, this is why our design looks as it does. All you do is bolt your factory rubber motor mounts to our K-member. Take a second and look under your hood and you will see
Let me know if I can help anymore. Thanks!

Im sorry, but the passenger side motor mount is 2pc just like the drives side. On the drivers side the cast iron portion of the mount bolts to the K-member and the rubber portion of the mount bolts to the block. On the passenger side the rubber mount bolts to the K-member and the cast iron portion of the mount bolts to the the motor. Here are some pictures I found doing a quick search.
This is a picture from the front of the motor. The cast iron portions of the mounts are red, and clearly on both sides.
Passenger side mount, with cast iron portion bolted to the motor.

This is what ive been looking for, but know one offers them.
I just ordered a PA k-member with LT1 motor mount pads built in and Madman solid LT1 motor mounts. Hopefully these parts will all work together. 
On what model Kmember, with what mount mounts. For that weight diffrence?
A GM LS1 Kmember with the cast iron engine stands weights 56-57Lbs.
The current normal BMR steel Kmembers with LS1 stands weighs 25lbs FYI. How did you only get 27lb savings with LCAs also? Was that an older one without the egine stands, and you had to reuse the heavy cast iron ones?
Dose anyone else, have weights of there parts they can list.
