Corona/Peugot/Hilux into AE86 HELP!

[ONCE-NA]

I've searched everywhere, maybe i'm not typing the right things.

I've put (sorta) the Corona/Peugot/Hilux setup from my TA22 i'm parting in my AE86 but the rotor fouls the LCA right near the balljoint.
How do people get around this?
I know AE86 guys use the XT130 LCA's but I assumed it was for drift camber yo! Does the XT130 LCA have a small balljoint or something?

yep i had the same problem, funnily enough the solution for me was using ta22 steering arms!

[ONCE-NA]

So the AE86 LCA and TA22 steering arm? Does it mess with your steering geometry or are the imporant holes etc in the right places?

[SeptemberSquall]

iirc I experienced the same problem with the same setup in my ke70 (similar suspension to ae86. rotor fouled on lower control arm.

I found the only place it fouled was on a pressed lip which protruded from the end of the arm, I radiused this part off on the bench grinder and had no more problems. advantage of this arangement is you can retain the original steering arm and hence the original steering geometry, rather than change the steering arm to a non-standard one as suggested above

[cri_ag]

Yes that's right. From memory everything bolted back on no problems. No geometry issues that I am aware of.

Aparently there is a fix with an NRCA, but that would give +25mm track each side and a few deg camber. I'm gonna grab a spare TA22 and RA40 steering arms and LCA's tommorrow and see what I can do. I don't mind taking a bit off the lca with the grinder but I'm worried it will weaken it and then I still would't be able to run a standard RCA and the car is pretty low so I really want to

[cri_ag]

i started to grind a set down but after i realized how much had to come off to allow even the smallest amount of clearance, i decided it was not the best idea.
my setup runs xt130 struts, 40mm RCA, ta22 arms, stock ae86 LCA

[ONCE-NA]

Awesome! I have clearance with the TA22 steering arms and they are the right length etc, and the hole for the ball joint is central on the arm whereas the AE86 one is offset to the outside bringing the strut in and too close to the LCA. So I will have at a guess 5mm more track each side and a bit of camber obviously.
I still cant run the RCA's, I was going to try an RA40 LCA which is apparently the same as XT130 (10mm longer than AE86) Which may give enough clearance to run my RCA's. Or failing that get some NCRCA's.
Anyways I ran out of time to fiddle with timgs today, maybe tomorrow.

Shit I accidently gave you negative rep! Sorry mate

I have them on a ke70, no problems with fouling, do you have the caliper on the front or the back?

[ONCE-NA]

I had to swap the struts left to right to get the calliper at the front to clear the steering arm originally, I havent tried swapping them back, (its a bit of a job having to swap the strut tops too) I wouldn't of thought that would make a difference to the rotor hitting the lca

[old_school_jap1]

have you got the different-sized piston hilux calipers or the equal-sized ones?
AFAIK ra40 lcas are 300mm and they have the same balljoint as xt130, ta22 and ae86

[cri_ag]

equal piston sizes work best on the ae86 with hilux brakes, otherwise your pads will wear uneven.

[old_school_jap1]

Quite the opposite Craig, the different-sized ones will give better pad wear as that is the whole reason they were designed with different pistons, the trailing piston is bigger and evens out the pad wear, this is only if they are used on the rear of the rotor as they were originally intended. Put them on the front of the rotor and they will eat your pads quicker though. This is why most high end calipers have different sized pistons.

[3jcelica]

Aplogies I read it a caliper fouling.

What hubs are you using? Pretty sure mine are all rt132, there is some difference in the hubs between rt132 and xt130 but from memory I think it was only a few mm
