MA61 – GH Sigma LCA Upgrade - Negative Camber + Extra Track - GUIDE

[Gilly]

GH sigma arms are slowly becoming a less popular option for AE86ers now. only due to the fact that with camber tops set all the way positive!! we still end up with 3 to 3.5* neg camber which is hardly streetable and causes a fair few tyre to guard clearance issues.

found the Corona XT130, RT132 and RA40 celica LCA's to be a good alternative. they are from memory just over 10mm longer than stock, which according to the measurements provided above are pretty much the same as our 86 arms.

best part being no mods required everything bolts up, normally ending up with around 2* neg camber and slight track increase.

not as extreme as GH arms, but still an option.

i would still choose sigma arms though!!! massif camber FTW!!!!!

there is the next set up you could use the later model simga lcas
the ones i am runing are 360mm i think it's gk not sure but this give you a massive track and camber if i recall at one stage i had something like 6.5neg degs then with the adjustable sturt tops its soming like 4.3 neg degs although i have never seen how much camber i can dial in with the adjustable sturt tops hmm

Gilly, I can relate to the tyre to guard clearance problems however some new smaller tyres and a smaller spacer should fix that. Good to know though as i didn't know you still get such massive camber with the adj strut tops all the way in!

I might have a look into the XT130, RT132 and RA40 LCA's one day and see what they are like.

Sam, 360mm GK arms... Thats insane! Heh, i might run them if i was looking at a custom race setup with really really flared gaurds. Heck i think 6.5 degrees of camber might be too much even for the track though. Good to know though still. Cheers!

also worth mentioning that the arms are a bitch to pull out of sigma's too!!!

he he, thats exactlly the mod I did to my GH sigma (scorpion) to give some neg camber, GJ LCAs.
So the sigma mod works on sigmas too

no harder than any other car afaik, and Ive done a few.

^^^ i remember them being a pain, from memory the LCA bolt to crossmember wouldn't come all the way out as it fouled on something. could be wrong, often am.....

I had a set of these in a KE35 IP car - with adjustable tops I had anything up to 7 degrees negative and from memory about 75mm increased track. That turned in quite well

damn sam, you are quite the weapon are'nt you!! Thats a very handy mod for me, when can i come take the said items for my beast its exactly what i have been wondering about for ages, which arms to give more camber and lock with quicker steering. You are a genius mate + rep x 100,000 Also your cars lookin hott too!

[Negative Boost]

Haha, cheers mate. We'll i'll be coming up north around the 20th of january and i'll be swapping my stock LCA's back in for the trip up the highway. So i'll bring them up then for you. Also check out suprawes's write-up on the AE86 T3 strut rods. They might be near $300aus landed but i reckon they'd be well worth it.

And guess what, i put a dam crack in my front bar tonight. About 10cm long, not happy dammit.

Tisk tisk for back street drifting, you know better

[Negative Boost]

I refute that acusation. It wasnt back street, it was in my drive-way. Drive-way drifting, its a new thing

I was rolling my car back off some ramps and the front corner hooked on the top of the ramp and tore as i rolled down. Silly mistake.

[RObErT_RaTh]

Ouchies Yeah I know how much ramps can suck, they look easy in principle but I was nervous the first time I used mine for the fuel pump. So afraid of crusing off the end

Driveway drifting aint new It used to be one of my daily joys in the ra60

[RObErT_RaTh]

You guys are teh crazy, but I suppose all that front neg camber comes in handy for this 'driveway-drifting'

[ViPeR_NiPPleX]

im actually thinking about doing my neg camber upgrade tomorrow... car needs a new tie rod, so why not
