Default Adjustable lower control arms

Ok, I have been doing research on ALCA's
Who has them, what kind are they and how do you like them?

I have the front 6GT3 LCA's and no complaints. You don't need to change the rears. The RSS units looks prettier though. I'm running -2.5F/-2.2R.

I'm running the RSS LCA's. The RSS are monoball, but I honestly don't think there's a difference between running GT3 LCAs and RSS LCAs. I went with RSS because it was little bit cheaper and they looked sexier (which means nothing since you never see them). RSS did have an issue with a faulty part in the LCA which was prone to breaking, and my LCA was part of the recall. I give them props for owning up to it, providing the replacement part, and paying for the labor to have it fixed.

Ben and Joe,
Thanks for your responce.
Ben, did you get yours thru Suncoast?
Joe, I do like the way the RSS units look and it seems as if the bearing is replaceable if it becomes worn.
Replacing a bearing is better then having to replace the whole arm.
It looks like Renline has something to offer but I am not sure if it is what i am looking for.

I have RSS LCAs as well (fronts only). Very pretty, monoball, relatively cheap. Current camber = -2.5(f)/-2.0(r). I believe GT3 LCAs need new trailing arms.

Very happy with RSS LCAs... until I heard that there had been failure(s) on the track. Was kind of disturbed but Joe put my mind at ease - it must've been the reason for the recall. Gonna try to get little more negative camber in the rear next year.

BTW, there are 3 choices. GT3, RSS, and Elephant racing. The last one sounds promising but I've only heard of 1 person with them installed.

I had a local shop source and install. They got them from Tarett Engineering. I believe the bushings on the GT3 LCA's are also replaceable because there is an option of getting the monoball vs. factory rubber bushing and you can change them out after the fact (at least that was what I was told). http://www.tarett.com/items/boxster~...-arms/list.htm

I called Rennline and what they have is a camber plate.
It mounts on top of the strut and gives you -1.25deg camber combined with the -1deg of the stock control arms you can get a max -2.25deg.
From everyones feedback that, -2.25deg might not be enough.

I have RSS front and rear on my CR. I bought them from and had them installed by Sharkwerks.
The RS has RSS monoballs pressed into the factory pieces. If I ever have to do it again, the RS would get RSS Tarmacs, too. It's actually cheaper to buy the whole arm than buy the individual pieces and pay an alignment shop to do the work.. plus you get the camber shims on the front that way, too.
It's also a lot easier to change the monoballs in the RSS links if they fail.

And they are very cool looking.

Roger that and you can configure them with either adjustable thrust arms bushings, solid inner monoballs... plus they come with plenty of shims (extra usually) so they work out pretty well for us:

I've been running the GT3 LCA on my Cayman for 5 years with no issues. I did replace the trailing arms but this can be avoided with shimming. At the time, the GT3 LCA was the only choice. Today, I'd go for the RSS. The final camber setting is dependent on tires and other suspension mods. I'm running - 3.0 F and -2.5 R. You might consider adjustable rear toe links in your package as these will replace the easily knocked about eccentric screw used to adjust toe.

I am looking at the elephantracing lca.
I like how it has no spacers.
It uses a single threaded connector, easy to adjust.

It looks like a nice piece, but the adjustable connector worries me slightly in terms of reliabilty over a shim. The shims are bit a of a hassle during installation, but once they're in, they're not going to break/move/slide. Let us know what you think if you end up getting the elephant.

I decided to call Elephant Racing.
I talked to Chuck Moreland. He explained to me the design advantages of there LCAs.
Using a mechanism with right and left handed threads is a standard industrial solution to adjusting anything that needs adjustment.
Elephant racing has taken an industrial approach to there design making it very strong, easily adjustable and very reliable.
I was very impressed.
After considering all the options, I ordered The Elephant racing LCAs!
I received them the other day.
The picture of them on the web site does not do them justice!
They are very well made. I would use the term rugged.
Now to get them on the car.
