I just measured again to triple check. Looks like there's a 1/8" difference in the lower control arms, and a 1/8" in the upper.

Is this a factory discrepancy?

 

Are the discrepancies on oposite sides??? So 1/8 on the driver swing arm and 1/8 on the passenger control arm?

That might be exactly what the problem is.

 

Right. There is a 1/8" difference between the passenger and driver side RUCA's.

There is also a 1/8" difference in the lower control arm between the two sides.

 

Figures, way to go Scion/Toyota quality control. They need there ISO certification stripped if they have it to begin with.

 

could this be to compensate for driver's weight?

My rear camber passenger side looks off (and i'm not even dropped). took it to the dealer and they put it on the alignment machine and said it was "within spec", but it LOOKS visibly off. It really does drive me crazy.

 

I really don't know. I'm waiting for someone more knowledgeable to give an answer. If I had to speculate I'd say maybe one side of the car is heavier than the other so this design was to compensate, but I'm probably wrong.

Maybe there was a discrepancy in the arms but since the stock suspension could be made to reach within spec they decided it was fine. When we lower the suspension this difference is exacerbated to the point where the alignment can no longer be made to meet specifications.

I'd be interested to hear if anyone has a lowered suspension and does not have this issue.

 

Well knowing that we are off by 1/8" on each side, then we can add some washers to the correct locations of the knuckle and be able to "fix" the camber.

 

I just talked to my friend at a Toyota parts department and he told me that all tC's built between 08/2010 to 11/2011 use a lower control arm with the part numbers:
48730-75010 (right)
48740-75010 (left)

All tC's built after 12/2011 use the part number 48730-21120, for both sides. No pricing was available yet. Perhaps to fix the camber issue, in an indirect way. I don't know.

He also mentioned that the upper control arm part number has not changed from 2011 to 2012 models, so I was wondering has anybody tried the adjustable upper control arms by Hotchkis ?

 

Link to said hotchkis part?

 

Oh boy, big mistake on my part. Sorry. I see now that the upper camber arms are for the 1st gen, ie. upto 2010. Must do more research before posting.

 

^^^ LOL, NBD

 

S tech springs for 7 months now. Camber problem is visibly noticeable . Among a slew of other complaints.

IMO, this scion was thrown together with little thought, due the fact the fr-s will overshadow every scion to date. Enjoy the after market support while it last.
They did the same thing with the 05 si (ugly hatch), then released the cleaner 8th Gen civic.

 

UH OH GEORGE!! where's 1stONE with his chime in???

 

i've talked to many companies...from presidents to r&d to salesmen...yes, almost all of them will definitely do the FR-S/BRZ, BUT...many are also VERY interested in the tC2 and the xB2/2.5

anything older than those are pretty much dead to them (meaning the xA, xD, tC1, xB1

so just wait for all the FR-S stuff to die down (probably a few months after the first batch is release sinced most companies want their stuff out around the same time - May)

 

Did anyone try this?

 

If it's 1/8 difference then i wonder is the driver side longer than the passenger side? if so, then why not try using the driver side upper part on the passenger side?

Also, who here had their car lowered with TRD's at the dealer? And what was their explanation from dealer tech's about it? Just a thought. This issue is really bugging me. I had my '09 Tc sitting nice on S-tech's and loved the ride with factory struts. Buyer's remorse i guess.

 

Every 2011 Tc I have looked at has this problem from the factory. Even at stock height you can spot it a mile away. I have not seen the 2012's yet, not up close anyways. if the suspension arms are shorter which makes total sense, Scion should replace them all with the proper length arms.

 

I don't know if this is BS but someone from my dealer told me that some springs for Toyota are not only biased by front to rear but also Left to Right. They said that it's a safety feature that if a driver falls asleep that the vehicle will slowly veer to the right over time. I don't know if this is true, but was just curious if anyone thinks that it's even a possibility. This is the explanation that I got from the dealer for the camber being more aggressive that the other on the rear. Sounds BS to me.

 

I second BS

 

I third BS

That might be one of the dumbest things i've ever heard a dealership say
