eccentric bushings

anyone have any experience with eccentric bushings? might be a good way to get more negative camber with the oem lcas?

found this, but oddly only for the rear toe arms, nothing for the control arms ...

at $390 a pair, it's not a cheap mod.

And they only fit Porsche/TRW arms, or aftermarket with the exact bushing diameters, Meyle has slightly larger and so these won't work with them.

I think powerflex makes an eccentric poly bushing... Much better pricing...

Not much better pricing

still $150 less - thanks for that find. i guess i was not aware of this because everybody says that the gt3 arms are the way to go. but for a street/track application all you really need is a little bit more, so something like this should do the trick. i'm currently around -2.8 at the front at m030 ride height, eccentrics full out and camber plates full in - how much more negative camber do you think 6mm will get me?

I heard 10mm of shims on a GT3 arm gives an extra -1 degree of camber so I would guess that same ratio, if it is truly offset 6mm, then an extra -.6.

I have GT3 arms I got them used, but nowhere near $250, if it works for you it would be a good $$$ saver and a good alternate solution.

I'm at USA M030 height and running -3 front/-2.5 back and plan to stay there for a while, it seems to be a good match with the Hankook R-S4 I've been running.

i have to pay more attention. first, no eccentric bolts on the front, just the rear. and the 6mm i was quoting was for the toe arms. elephant says to expect .39 increase in negative camber in the front.

For that money, you could buy the elephant monoball camber plates that give an extra -2 and sell the ones you have now (Tarett? That give an extra -1) and make back most of the money?

It looks like a tough process to retrofit those bushings...

i have the camber plates that come w the ksport coilovers. figure i get -1 from oem and -2 from the camber plates. elephant has a little tool to press the monoballs out - install can be done with control arms still on car (no messing w ball joints). another $75 however.

I think The tool doesn't work on our LCA, I think rennline has a better video/instructions for LCA bushing replacement, you have to chisel.the two sides out after heating it up, it did not look like fun I had been emailing Chuck from elephant a while back about them when I needed more neg camber in back and was looking at those eccentric monoballs. Ultimately I ended up with adjustable control arms to get my extra -.6 of camber in back.

Ksports, those plates, I can see you getting -2 extra with them, they have quite a range.

If you dropped 5mm all the way around I bet you could get some extra neg camber from that, but if you have the car setup good otherwise I could understand if you didn't want to do that. When I had Ksports I had them way too low (it looked really good ) but handling took a hit. If I ever get adjustable coilovers again I would probably lower to row m030 height but no lower.

I have regular monoballs on my front LCA, I love it, especially when I do any suspension work because the arms drop right down and are not bound by the rubber bushing.

hey - here's another foolish question - do they make a bushing or monoball or whatever for the chassis end of the thrust arm?

I think EPS does one with a supposedly stiffer bushing or whatever there. reviews are inconsistent
