Which one will provide the best suspension upgrade - LCA or UCA?

Or does it make sense to do them both at the same time?

Do one piece lca's and an adjustable uca both at the same time IMO.

I went with both at the same time also. All adjustable from Steeda. Contact Gus and he will discount it for you.

I personaly went with the roush aluminum ones with stock bushings. They are nice units but if your looking for dragracing they are not what your looking for. They are compliant for day to day, but stiffer on the twisties, also for the price they were unbeatable and fit what I was looking for down to the letter. I got mine for 165shiped if im not mistaken directly from roush. I then did the watts link with helped the car quite a bit. I also did the steeda adjustable UCA, with street bushings. It helps on launch quite a bit actualy but still within reason for NHV, although NVH is a relative thing but for comparison I find the stock exhaust on my gt loud enough, tetering on too loud.

To me anytime you replace stamped factory steel parts with parts that are built to higher tolerances its a good thing.

My car had a considerable wheel hop problem (magnified by the stock Goodyears going to crap under 40 deg f) I installed the UMI LCAs and LCA relocators and it solved the problem really well. So I'm inclined to think LCAs (easy to install as well) are probably the better of the two if your choosing between LCAs and UCA.

I did Steeda adjustable LCA's last year and it really did the job, but the increase NVH is pretty bad. I got used to it, but there should a happy medium. If I ever do it again, I'd use softer bushings.

I'm thinking of getting J&M LCA and maybe the adjustable UCA

Here the link for the LCA

Is it really going to be that much harsher as the previous poster stated?

I'm not sure about UCA's but I love my LCA's.. Really helped with wheel hop

bob

Even going to urethane will increase NVH and it takes some gettig used too.

UMI makes some neat stuff with thier rotojoint equipped UCA's, LCA's and Panhard Rods. Its essentially a bushed and sealed sphereical rod end (Edelbrock uses the same or similar on thier LCAs)

I went with:

I am very pleased with this combination.

Are they installed yet?

That LCA looks really interesting.
It's sort of expensive.
How do you compare it to the J&M LCA that has a "polyball" joint.

bob

Roto-joint, Johnny Joint, Poly Ball bushings - they all attempt to solve the same problem, it just depends on what your preference is. I'd say the Poly Ball bushings give the best NVH performance, but it seems like they might suffer from deflection more than the roto-joint (the roto-joint is a steel ball set in delrin bushings). The poly ball also looks like its more susceptible to intrusion by contaminants (but probably no more so than a regular urethane bushing - easiest solution would be to use a marine grade grease that repels water as a lubricant).

i have been running J+M poly ball LCAs and a spohn upper with a rod end...been very happy for 3 years...also a j+m adj panhard and relocation brackets... the rod end UCA does send some nvh out but its not bad.
