Default Aftermarket K-members - up to street abuse?

What are peoples' experiences with the aftermarket
lightweight K-members, as far as their ability to
stand up to the street - potholes, the occasional
bit of curb surfing, etc.? With the lighter weight
I'm suspicious they might be more easily bent at
the A-arm mounts, but I'm highly tempted by this
BMR K-member GP that Speed Engineering has going.
This is probably my best chance at front end weight
reduction.

What's the word on reliability-under-casual-abuse?

Mine is doing fine and I have almost 10K miles on it. You will feel alot more on the road. DO NOT HIT POT-HOLES. Little ones feel extremely bad. Other than that I like mine.

I've been very happy with my BMR setup. Have a little over 10K miles on it, which includes 2 trips to Florida.

After seeing/owning a couple other brand K members, IMO the BMR is the best for a mostly street car.

I looked on there the other day, and nothing but Mustangs.
If you have a seller handle or a handy search tag, PM me?

I dont' believe you will find any that are truely "street legal". Though doubtful, you could be sited for not using proper equipment on the street, or not pass inspection...this is more then unlikely going to happen. I would say the only time this would ever come into play is if you were in a fatal accident (i.e. other party died). If they examined your car, especially if the malfunction was a direct result of your aftermarket non street legal component, you potentially could be in some trouble. This would be for almost all aftermarket suspension component, not limited to a k-member.

This is the same scenerio for our Bogart rims.

This doesn't mean it may not be strong enough for street use, it only means from a legal standpoint, they are considered a drag racing, offroad use item.

Less weight doesn't necessily mean weaker. The construction and material properties of the pieces effects the output of strength to weight ratio.

Many of the K-member designs out there are very nice. Choosing ones that replace motor mounts is going to save you a bit more weight. I've seen comments stating that this design can be "weaker", I will strongly disagree.

Steve10,

You raised a point that I had been wondering about.
What about SFC, STB, or a full cage? They change the crash characteristics of the car.

Sorry JimmyBlue, I dont mean to hijack your thread.

Unless the manufacture can provide proper documentation w/numbers, they more then likely won't be street legal. I'm an engineer, not a lawyer, so this area isn't my expertise...but it is something that we do have do take into consideration as a consumer.

All the components that your considering are RACING parts. Even though they can strengthen a car, they do change certain aspects of how it will perform. This is why you can't even take your STOCK seat belts out and use a 5 point harness...it is NOT certified to run on the street, you can and WILL get a ticket for that one...

I see this come up regarding our rims...for obvious legal issues, our drag rims as well as others are to be used for drag racing purposes only.

Some of the points I've brought up may be far fetched from some folks perspectives, BUT it is something that we have to take in consideration as a manufacturer.

I figured that would be your answer. I just dont want the insurance company to blame an accident/damage on an aftermarket suspension part.

I could see it happen though. They try to weasel out of paying a claim because you've installed urethane suspension bushings, which obviously made your car dangerously unstable and caused the accident
That would be like a dealership voiding your warranty for dubious reasons, like a completely unrelated modification you made to the car

Face it, if you are involved in a fatal crash, even if you are running aftermarket parts or not, you are going to be sued anyway. And, more than likely, it is not going to make any difference if you are at fault or not, there is almost always lawsuits in fatals.

Well, I ordered up a BMR one since they at least
claim theirs is up to the job and nobody's had any
bad experiences with that one to tell. As to the
legal implications... I guess with the poly bushings,
lowering springs and other accumulating non-stock
gear, I'm a ripe little apple on the bough anyhow.

I am not talking about a fatal accident. Thats a whole different story. Im just talking about one where your car gets messed up and no-one is hurt or just minor injuries.
