If you had to buy one before the other, which is more important, LCA's or UCA?
LCA's tend to be cheaper and are a do-it-yourself install.

UCA's are moderately more difficult.

Out of convenience, I did the UCA first and it stopped the hopping.

Get both if you can, but If you have to choose one or the other I would go with LCA's hands down- get some relocation brackets with them. UMI sells them in a kit, LCAs and relo. brackets for around $200 I think. Makes a world of difference and a pretty easy install

lowers for sure, non adjustable and greaseable.

I think that all depends on what your doing with the car.

OP, why are you doing control arms and what are you trying to accomplish? Are you lowered? What are your mods?

true, but the only way i would figure you would do an upper first is to adjust pinion angle

if he was planning to lift it or slam it then i could see the UCA being a more pertinent mod, but 9 times out of 10, people are looking performance. the stock LCAs flex bad, and unfortunately, flexing LCAs hurt performance more so than a shitty UCA.

i'd say the LCAs are a no-brainer. the only reason people even buy an aftermarket upper is to correct pinion angle.

How so out of convince? Installing LCAs is much easier than installing the UCA. Much easier..

I agree. Although I will add that the UCA does make the car feel a little "tighter" during hard launches considering it's got a lot stronger bushing than the OEM bushings.

I generally recommend LCA's first, for a few different reasons.

The main reason, they are the most effective way to rid wheel hop, and help with traction.

Both the UCA and LCA's in factory form, are less than stellar, by design. Upgrading either will yield better performance. In our testing, the Lower Control arms have proven to be more effective.

Also, as mentioned....the Lower Control Arms are indeed an easier, and quicker modification to perform.

If you have any other questions, feel free to ask!

Andthat is why I asked. If he has a one piece ds and is lowered the I was gonna tell him do the upper first. I agree that lowers are easier and I did the first but now im looking to tackle the upper

Sorry for the delay was working all day and no chance to check the thread. Why im looking into this is because my car wheel hops really bad and has spin on launch. So im basicly trying to eliminate the wheel hop issue the most.

If you want to eliminate wheel hop, get yourself a quality set of lower control arms.

Check out these bad boys
