yes they will bolt on. would be a good idea to get new ball joints and bushes as these cars are old now. the sigma bushes also need to be ground down to fit into the ke70 LCA mounts.

dont forget to use the "press on ball joint arms" and not the "bolt on ball joint" ones. they are approx 330mm long.

[egg_83]

you will also need to change tierod ends to ra40/t18 style with the adjuster tubes

[scott_22]

thanks boys

[scott_22]

just about to order the parts so all i need is the sigma arms them selves, new sigma ball joints and ra40 tie rod ends?

[Sam-Q]

you know that this is more for looks than any sort of upgrade usually right?

[marvis]

Agreed. I would go Rona arms. Sigma arms give way too much camber... You will be under steering everywhere.

marvis

[bigm]

agree with marivs
i used to run them and when i was spotted at skidpan, marvis refered to me as the "yellow understeering ke70" LOL
now running ke55 (same as corona)

[Hokey]

aren't you running s13 lcas in ur car mavis? which is bigger track than sigmas i thought

[resol]

i ran rona arms, then i changed to sigma. they ARE an upgrade. IMO.

the car hooks into turns more. even in the wet my car does not understeer that bad (compared to dry). a good pair of tyres and a good wheel alignment will help more then camber anyway.

also if you run lots of camber, dont forget to wind the castor off. i have found that lots of castor and lots of camber=understeer. while more of one then the other gives good results.

I would say that sigmas give WAY too much camber for the wet. if your planning on using it mostly in the dry it may be an upgrade.

i have corona arms in my ae71, gives about 1.5 degrees. and as of yet i have not experienced understeer in the wet AT ALL.

granted sigma arms make rollas look hektic.

[FAST EDDIE]

ke55 hey same as ke30??

[Clinton]

they are good if your running like 245s

i dont understand where this new "popular" opinion is coming from.

you dont put longer arms in for more camber. you put them in for more track.

30mm a side is a lot, but its not too much. you want to have adjustable tops already if you plan to run sigma arms, cos you want to be able to adjust them positive to neutralize the camber somewhat. which you easily can within the normal range of adjustment with adjustable tops.

for a drift car with not much power, a much wider front track than rear is a plus.

set your camber to -3* and youll be smiling. as mentioned you need the ra40 tie rods. not just the replacement end piece though, you need the turnbuckle tube as well. youll have to get this 2nd hand from the wreckers.

i dont like the sigma arms, cos they dont really fit properly. the ball joint taper is not the same (though it is all but proven to work safely) and the bush and crush tube needs grinding down. but in all practicality, its a good upgrade for a low power drift corolla.

[Sam-Q]

yeah thats why I said usually, because from what I have seen people just normally chuck them in for the "hectik" camber. I know some people jusy do it for the tract increase by putting the adjustable campter tops all the way out to counteract but that doesnt seem every common to me. But I could be wrong as I dont pay that much attention to the members rides.

[Hokey]

gotta be the oldest argument ever haha

[Sam-Q]

whats that, the whole mega camber is good or bad?

[scott_22]

going ronas now. was talking to someone with experience.
thanks ppl

[Sam-Q]

just to double check xt130 is the same as ra40 right?

[FAST EDDIE]

have rona arms in my street car gd3's understeers, havd to go up to -4 degreese in my drift car to overcome understeer so massive camber can only be better!!!

whats the deal with the press in ball joints vs the bolt in ones, why cant i use bolt on ones?? only reason i ask cos theres about 10 siggys at upullit and all ahve bolt in balljoints?? if no good what model did the press in ball joint lcas come in???

[marvis]

I have a RA65 Celica.

I'm well aware. But if you set your camber to where it should be (~-3deg) Running decent wheels it will be sticking out ridiculously, hence needing to run crazy camber for good fitment due to the track increase.

[scott_22]

marvis your my hero. your like an encyclopedia

[driftke70]

i ran sigmas for a while, i found the for turn in they were pretty much the same as lower camber, but mid slide you have much more traction, my car never really understeered that bad, if anything it got worse when i made it more positive on the camber tops, which i had to do when i put my 14 x 8 - 16 on the front, mucked around with my guards, put more camber in and bobs your transexual aunty.

hardly anyone on this forum has decent wheels. most people who are considering running a sigma lca will be luck to have a 0 offset wheel.

i can say from direct experience.

i ran 14x6.5 +10ish wheels with sigma lca on my ke. NO guard mods. normal camber setting.

http://www.ae86drivingclub.com.au/dcimages/1/8/8311.jpg

i ran 15x7.5 -5 with sigma arms on my 86 normal flared guard.

http://www.ae86drivingclub.com.au/dcimages/1/8/13051.jpg

its a good set up for a low powered car. its simple suspension tuning fact.

if you have a lot of power, and need more stability, run more rear track. if you want the car to turn in better and be more twitchy, run more front track.

[marvis]

How much camber were you running on that 86? Looks like a fair bit? or is it just the slope of the road?

And the stupid thing is.. People throw them in without camber tops so they have the track increase but they can't change the amount of camber it's running, so it's just useless as it's running show camber (Sigmas give you like what Negitive 5 Degress with stock strut tops?). That's what I was trying to get at before.

[slydar]

the cars parked on the shoulder. look at the roof :) it had 3.5 degrees. its the exact same setup in both cars, took it out of one and put in in the other.

when you put sigma arms in, you actually end up with a lot of castor too, the bolt holes for the tension arm is further out, so you have to pull the lca forward to reach.

i dunno, ive run the set up, i find it good. that ke had a stock 4age in it, and it was a fucking weapon. just a lot of fun to drive, heaps of fun to bash around in on the street. did lots of street drifting in that car.. by far one of my favourite cars ive owned.

can anyone shed light??

[resol]

FAST EDDIE: bolt on sigma arms are 360mm long, which is EPICALLY long for a XE7X and the like.

i run sigma arms for the camber AND the track, not just one of the other. i also have xt130 strust which ad track but reduce camber. and stock struts tops

i think i have around -4 camber. with stock guards and ma61 rims the wheels sit outside the gaurds. as i said the car drive better in my opinion with this setup then with rona arms. i also run toe out and us much castor as stock guards allow.

edit: i dont think people should mod their car because they read it on the net that lots of people do it. i think you should take other peoples opinions into account and figure it out for yourself. im sick of seeing cars that all have the same mods in them and you talk to the owners and the just speel off all they crap they read off the net.

Sigma's are wak.




:oh:

if you want control arms for the extra track, then i would say invest in some adjustable control arms, that way, combined with camber tops, you can fine tune the setup to suit yourself/engine/power

[Ramcam]

Hi there people,I have a AE71 with RA60 struts and im experiencing positive camber.I want to fit Sigma control arms(press in ones) would this be my best bet.I only use the car for cruising,not drifting(yet).Your help is appreciated

[thepunisher]

Im pretty sure the gh sigmas have a press in ball joint (80-82?)

How much camber do sigma lca's give you?
Just wondering how silly it is.

[Ramcam]

Hi, I am not sure how much camber it will give me,I just want to get rid of my positive camber.Having a bit of negative camber wont hurt.

[Sam-Q]

matt= negative roll center adjusters make your scrub radius even worse, if you can get normal spacers and a longer arm

[Ramcam]

OK guys,what i really need to know is has anyone done this conversion(AE71 with RA60 struts and sigma control arms)if so how much negative camber will it give me?Your help is appreciated
