I have UMI rear lowers on my ride. They work and look good. Make sure you get a set with roto joints on one end.

Most of the front upper control arms on the market are overpriced IMO. I went with tubular UB machine and would highly recommend them. UB machine is the manufacturer. Speedway markets them for the circle track guys and they are very reasonably priced. I bought mine from Speedway motors and have been very happy with them. When you order, make sure you tell the sales guy you are not running your car on a circle track. The LH arm has a funky camber angle designed specifically for circle track racing. With that said, you need to buy (2) RH control arms and you just flip one upside down for the LH side. They are symmetrically opposite so flipping one upside down works fine. They are quality pieces, they look good, fit great and take weight off your front end.

I have to admit, before I bought them I was concerned with their strength. When you compare the bulk and weight of a stock, stamped steel control arm it makes you wonder. I posted on turbobuick.com looking for input and got a lot of positive feedback from the GN guys. Some of them responded saying they have been catching air on launch and bouncing the front end with no issues. Others said they were in front end collisions with no issues.

This may help.....

Do you mean upper and lower A-Arms?
Really? They are know as both, people call them A-arms, technically they are control arms. Some guys call them a-frames. If they aren't the shape of an A, some people call them wishbones.
 
UMI designs, manufactures and tests their products so why not ask them in detail what the advantages are of using their front control arms. I use their rear control arms and had the lower one custom made for no more than the cost of the extra part. I like their products and their customer service
 
I have not heard much about the UMI arms but I can say that the SPC a-arms are impressive. Only brand of front control arms i've found to be adjustable and heard tons of great reviews. give mark at SC&C a call and he will educate you more then you may want but he really is the man when it comes to suspension knowledge. i'm currently trying to budget in the sc&c stage 2+ package. basically fixes all of GM's huge mistakes with the front end geometry.
