Default Which uca/lca combo

Sup all, SO the noise coming from the non-existent bushings in both my lower and upper control arms has gotten loud enough for me to look into replacing...
I dont have a big budget as I'm saving for a wedding and home.. Ive narrowed it down to two Combo's

first is the bbk upper and lower for 309 from AM

Second is pro street upr's

Which of the two is a better design, And is there something better I should look at in this price range? Thanks..

Personally I'd go with the UPR's over the BBK's, but I'm not a big fan of either of these arms. If you're racing alot like I try to, these bushings tend to get torn up pretty quick. Because I'm at the track often I went with the UPR spherical bushing arms. If you don't want that kind of harshness, I'd look into a poly arm like Steeda or Maximum Motorsports, they have a better bushing design so you won't eat them up as fast.

The link to the BBK's does not work for me, but the UCA's in the UPR set are a BAD IDEA due to the poly bushing on the body end, as spherical is MUCH better way to go.

Are the BBK's these...

If so...... NO, DON'T GET THEM as they are horrible for the corners and very hard on torque boxes. I like the UPR Pro Series UCA's to go with the LCA's in your second link. I don't know why they don't sell them together.
