I am in the market for a K member. How is the quality of the PA ones? My friend has one on his turbo car, but it doesnt see too much street time. From what i could see it was made well and the finish has stood up to a few years of abuse to far. I usually follow the maxim of "get what you pay for" but i am interested in this.... Can anyone give me some opinions on these? thanks.

Are you doing a turbo build also? Also how much is he asking for it?

Do you have any pics of it off his car?

Im not buying his, its still on his car.. i was going to get a new one (if i go with a PA). I want one for weight saving purposes, i am doing an NA build.

Are you set in stone with the PA K-member????? Or are you up for different opinions?

I went with UMI K-member.. I love the double support that it give you over the single.

Yes i was thinking on a UMI or similar pending what people have to say about street driven PA K members

i street drive my PA k member too, and have had no problems for 700miles it's been on my car, i bought it used though, so there's no telling how many miles are on it.

I know the older style ones break. Dunno if they fixed the issues.

UMI's have broke too.. I am going with PA Racing and I am a fan of UMI stuff

We have never had a K-member break on the street or under any road use. We have had a few minor issues, like a motor mount bolt being forced through a hole applying pressure to the motor mount bending the mount and cracking it eventually. To prevent this we gusset the motor mount and solved this from happening again. Other than that I am not aware of anything?

From what i have seen UMI is one of the best on the market and i run UMI parts on my 4th gen but to be honest i have been running a a PA k member on my 3rd gen since they came out and I have never had any issues. So I'd say go with the best price.

Think of it like this:
which puts more stress on the kmember? A pot hole at 35mph, or landing a hard launch where the wheels were 3ft in the air?

A buddy has a 3rd gen with a PA frontend kit. It drags the back bumper during the launch, and has seen in excess of 500 1/8mile passes just like this with no issues yet. But zero street miles.

I'm going to guess that landing a Massive wheel stand is going to be harder on a front end, than your average pot hole or expansion joint at road speed.

I'm not a k member stress analysis expert by any means. From what I've read in the past, the lateral side to side force that the wheels/lower A-arms exert on the k-member is harder on the assembly than the up and down motion absorbed by the shocks and springs. The lateral shock gets fully absorbed by the k member.

There was a recent thread about a PA racing k member that broke. For all I know it might have been 1 in mil.. but I'm not positive.

BMR Tech2

2000+ BMR K-members on the road and track with only two documented failures. Both failures were material failures due to fatigue in the front A-arm mounting boxes. They were not weld failures. These instances happened over 6 years ago prompting a re-design that eliminated the fatigue points by structurally integrating the A-arm mounts into the horizontal and upright tubing structures.

Our K-members are and always have been strong due to the design itself. Tying multiple points together in a structural fashion and/or triangulating and gussetting only the necessary high-load bearing points can keep the end product light and strong without resorting to using extra tubing where it's not needed or using fatigue-prone 4130 tubing...

The PA ones are hit and miss some fit better then others. You can see it with the rack mounted. They all don't fit like stock and crooked a little. But some the boot actually hits the front control arm bolt, so you have to grind the bolt down.. or it rubs thu the rack boot Some are fine, but there is defiantly alot more broken PA Kmembers and A arms then others, and I've seen some some some crappy looking welds for sure. And they dont have any brake line tabs.

I'm happy with my BMR, fits great, there strong, and light, the stock brake line brakets bolt right on really nice.
Jolster got the UMI one with arms on sale. And its not much lighter then what just the bmr Kmember saves with stock arms.
My BMR Kmember was 24.5 pounds.
the UMI one is 32.7
I think the PA one is 22.5 but thats without LS1 motor mounts, the BMR and UMI comes with.
I've looked into this alot the BMR one is hard to beat for weight, price, strength.

so you should sell me your BMR one, with the ABS delete lines

UMI and BMR are neck an neck quality wise imo. Design wise I would feel more comfortable corner carving with a UMI k-member. On the other hand for drag use and normal street use BMR is probly better.

You're an idiot and I hope no one here is reading your posts. Don't bash companies that obvious don't deserve it.

I'll do that if I go motorplate, get some drag brakes, and no powerboster
LL,no abs, all the lines and everything all bolt up nice.
