best k- member

Just look closely at the pictures. If strength and alignment range are concerns along with lighter weight, the UMI is the best one. The only K-member that uses two main tubes which gives twice the lateral support, and it's still 25 pounds lighter than a stock k-member. Add the fact the alignment slots are larger, you can get more negative camber if you like to run corners, or take more out if you do a lot of drag racing. You also can gain more caster too.
There are also different versions. The standard one for LS1's: http://www.stranoparts.com/partdetai...D=18&ModelID=7 The standard for LT1: http://www.stranoparts.com/partdetai...D=10&ModelID=2
And there are the road-race versions with gussets and extra supports added to reduce flex further: LS1: http://www.stranoparts.com/partdetai...D=18&ModelID=7

Drag racing isn't hard on k-members. Skinny tires severely limit the amount of lateral grip and thereby force going into the k-member, and any forces generated from landing a wheel-stand are put through the springs and into the shock towers.
Strength has to be put in context. I don't really care what a 7 second drag car has on for a street car that has plans for daily driving or handling. YMMV.

Duh, I have a UMI K member and bought it for the twin tube extra strength. I've not been to the track with my HKE 408, but have been somewhat concerned about effects after the front end comes off the ground. Maybe Sam Strano would like to offer more insight since his last post was diffficult for me to understand.

What didn't you understand? A K-member doesn't take vertical loads, only lateral ones.
Vertical loads, like a car putting front wheels on the ground after they've been in the air are tranmitted into the shock towers, not the k-member.
Lateral loads, like when you are turning are put into the k-member as that is what the lower control arms bolt into.
As for fitting turbo's. The stock K-member is bigger and bulkier. UMI worked hard to try and make sure that there was as much room as possible and little to no loss of space with thier unit vs. stock. The pictures you see on their site are off the RR version which has some gussets that cut into the available room. If you just think of the part wihtout those, that's the standard unit. I can't see how any kit that would fit with a stock k-member wouldn't with the UMI.

Same kind of single tube design. I don't think the workmanship on either sucks. It's the design I have an issue with, and that's the same with any single tube k-member.

I have a BMR K-member and it's a drag car so so side load is not a concern of mine but the way I see it the motor mounts on my K-member are on an outward angle at the bottom kind of forming a "wedge" with the motor. This "wedge" is going to make motor an active part of absorbing the side loads. As far as I have ever seen no has bent the front tube of a single tube K-member. Not saying the twin tube is a bad idea just that it's not needed.
