K member and A-arm advice?

I am looking to go with a new tubular k-member and new a-arms and would like to know if any of the 3rd gen guru's can give me any help in this dept. I am looking between BMR, UMI, PA Racing, and Spohn.
I will not be running coil overs, I just received my ground control weight jacks, and have brand new suspension all of the way around.
So, please give me your honest opinion on these products. Also, if you are a manufacturer of these products please let me know why your parts are better than the others.
Thank you!

Re: K member and A-arm advice?

Speaking for UMI i can tell you our products are made in Philipsburg,Pennsylvania out of "USA" material.

We design, test, and race all of our products and refuse to sell anything we aren't comfortable with putting on our own vehicles.

We Manufacture most every thing we offer including powdercoat in house!Nothing outsourced to any other machine shops.

If you need any info or pricing please feel free to call me here at the shop.

UMI makes some really nice pieces. I can say their k member fits beautifully and their a arms are very nice, stout pieces. If you go this route they are the way to go for sure.

If stock wont' work for you, UMI RR K-member. I read Weight Jacks, so I assume you are looking towards Road Course duty.

Stock unit is stronger than anything else out there, but if you have to have a Tubular K-member due to clearance issues, then the UMI RR is the way to go.

Re: K member and A-arm advice?

I guess I might just go with a set of A-arms for this winter. I don't really meed the k-member at this point. And knowing that the stock K-member will be stronger than anything else. I already have my turbo system built and installed. I was just looking for a cleaner look with a little more room for all of the turbo pluming under the hood.
Thanks for the input guys! And I think I will be ordering a set of the UMI arms, we will see what the black Friday deals bring.

Re: K member and A-arm advice?

I just installed UMI A-arms and camber plates this past weekend. I haven't driven the car but the pieces are well made as are the rest of the UMI suspension pieces I have installed. HOWEVER, installing the springs was a ****!! Seating the coil in the UMI coil pocket is not easy like it is with the factory A-arms.
