Default k-member

is a k-member really worth 500? is the only purpose to save 24 or so pounds?
i have most all the other umi goodies except the k-member. i'm very happy with all the other upgrades, but it's hard to justify 500 just to lose 24 pounds.

am i missing something else?

Depends on what your goals are and what you use the car for.. There are more effective things to do to your car before the K, but its your car your $$.

For me I want the weight loss and it is better for weight transfer since it is more loose up front with the hem joints but yet it feels tighter up front..

I just got one, but haven't put it in yet, but my buddy ramairws6 has put a UMI one in when he put his LS7 in which I have drove so that is my thoughts on the K.

Most people don't buy the uppers cause the stockers actually weigh less. I did get the uppers arms just cause I wanted the full deal.


Good luck in your choice.

k-frames make ALL work on the engine easier. There is more room to work, and things fit in easier.

i've also heard the opposite......maybe umi will chime in. anyone know for sure if the umi k-member has any fitment issues with american racing headers?

There are more effective things to do to your car before the K, but its your car your $$.
actually, there's not much left to do (engine or suspension). the car won't be auto x. it won't be track drag raced much. just really wondering if the only bonus is to save 24lbs? i've got a big brake kit by brembo, so it's not like i haven't destroyed the weight saving thing anyway.

thanks for any help,
rob

Hello Rob,

We have not tried our K-Member with those headers yet. However I see no reason why they would not. Any header designed to clear with the stock K-Member will clear with ours. We had issues with one header over a year ago and we corrected it quickly.

Hope that helps!
Ryan

I know of one setup that is worse with (another brand) K
member - the Random Tech high-flow catted Y, the one for
stock manifolds, would not fit with my BMR K because the
rear mouny "boxes" were too fat. Stock K tapers in tighter
at the rear mounts. It was the cats that interfered, I don't
think a header collector / primary would be close in that spot.
Point is, nobody knows until somebody tries....

buy spohn. same strenght. same warrenty. "will handle any road." less weight. unless you are road racing use spohn. and if you are road racing. UMI is more then 500 and less weight loss. so spohn is great. and they are only about 7 days out on shipping. got mine. looks great. works great.

Actually, we have LS1 K-Members in stock and our K-Member with motor mounts is $6.00 less expensive. Over $500 is for a road race version... designed for road racing and not just street racing/drag racing.

lol

everything except shocks and springs under the car is umi, i would have to have a huge reason NOT to go with them on a k-member.

thanks for info on the bmr and sphoon though.

ryan you miss under stood me. sorry i was saying the road racing one is more than $500, so if he was road racing buy yours is what i meant

second yours(UMI) and spohn anre the same warrenty. so if that is the case why not buy the one that ways the least.

UMI makes good Stuff

Spohn Makes good stuff

so Ryan i didn't mean anything negitive.

Don't do anything then. Make your car a better daily driver or show car with the money you spend on it. Weight savings isn't much of an issue for people who don't race. If you really wanted to be nitpicky, you could say that weight reduction helps gas mileage.

I have to argue with the notion they are the same strength. I helped Ryan with his, idea wise. And UMI's uses two cross tubes, nobody else does. Also, UMI's k-member has greater adjustment which making aligning the car easier, and gives you more ability to compensate either direction with regards to camber and caster.

So, if you really think they are the same that's fine. But I think you think they are the same because you haven't really compared them both in detail.

idk. if they both say they can take the same road. idk how you can say strength is different.
ok so they can adjust easier. well as long as you have new low front controll arms you can adjust just fine.

and still back to what i said first. SAME WARRENTY so money vs wieght. spohn is the way to go.

I'm not really in the mood to play "what if" games today, so I'll just lay my cards on the table and let the bickering continue.

What exactly do you mean by "take the same road". I assume you are saying you can drive down the road and neither will break, and that makes them of equal quality. Well, I can go buy tires @ PepBoys that are black and round and hold air and are size 275/40-17, but they ain't exactly BFG KD's, or Eagle F1D3's are they?

Do you have first hand experience with both K-members? I do, as well as others. So does Ryan, which is why we did something different than follow the norm like everyone else does. They seem to be content to all copy each other, we weren't. You don't address the strength, or that the addition of a whole other tube (which carries two of the A-arm pick up points) will indeed make the part stronger. On the alignment you answer is "just run adjustable A-arms". Ok, because they are cheap and everyone should be forced into them. What's more is that because adjsutable A-arms are they way they are, you have to remove them to adjust the length which not an easy task.

Instead, I get the distinct feeling you feel as you do for other reasons. What they are, I don't know. But I'd guess pricing or something, because it's sure not for technical detail.

ok so i saved money and wieght. and under the odd time that my spohn might break on the street. steve will repalce it.
no i bet ryan would repalce it to if it broke.
But now i am saving money and wieght And covered for and breakage problem

Well I guess you have it all figured out then. Of course, breaking isn't something I'm ok with since it only mounts my suspension control arms in place. And even if it doesn't break, flex isn't something I want there. I bet you don't want flex either, but I could be wrong.

Good, you're happy with your decision, and we now know what the criteria for your decision was. Money and replacement.
