is the alignment on the FRS/BRZ adjustable? - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Subaru OEM eccentric bolt has tick marks on the lip. I see none on that pic. To be fair - that pic above is the first semi-legible pic of the proper side of the bolt and all previous claims of 'no camber adjustment' weren't backed by anything other than words.

Be careful, Andrew, you don't want to give away too much information too soon.

IIRC MotoIQ confirmed eccentric bolts were not used on the preproduction FR-S either a few months ago.

Hopefully they throw the usual adjustable bolt in for the production car. I'm with you...I'm really surprised it wasn't in there already since they've used an eccentric on every car I've seen up to now. It would be a pretty weak area to save on costs for a performance car and I'd think they know better, so I'm hopeful but it's speculation right now.

Yes, w/o a supporting picture.

Ah, good to know...don't think I've ever seen the top of one of the eccentric bolts from Subaru before.

Yup...and I even posted the original story here when it came out...

Bizarre indeed. I hope they do the right thing too! Thanks for the insight.

It's not the distance from the bolt to the tophat that matters, it's the distance between the bolts. Think about it.

Ah , of course...

Heres hoping these cars get some front camber adjustability.

You can see a Scion Tc factory service manual at scionlife.com - it specifies an array of bolt sizes you can use in various combinations to achieve camber adjustment.

Perhaps to ease assembly/save costs, the cars will come without subaru style cammed bolts and all adjustments will be made with toyota/scion style 'crash' bolts.

I'm eagerly waiting for a look at the FSM's!

Jeff Lange · 03-21-2012, 05:20 PM

There are no multiple sized bolts like on most Toyota applications.

Most Toyotas have slotted struts and the smaller bolts are only for when you reach the max adjustability of the original bolts. Subaru uses cam-shaped bolts normally.

Looking at the parts diagrams for the FR-S, the upper bolt is definitely different than the lower, but it is hard to tell from the diagram whether it is a cam shape or not.

Looking at the diagram posted in the other thread: http://www.ft86club.com/forums/showp...11&postcount=7
it does look pictorially like the bolts are a bit different but the PNC numbers for the top and bottom bolts are the same.

What are the part numbers called for by PNCs 43211K(RH) and 43212D(LH)?

Any chance that additional part numbers will be added for a particular PNC with a later release/update of the EPC?

neveronlinefrs · 03-22-2012, 02:07 PM

Good info! I figured they would use something allowing for a reasonable amount of adjustability, but have not seen anything concrete thansk for the info!

PNC's are the same, but you can see that they have "No.1" and "No.2" listed as well, which typically means they are different, in some cases they may share the same PNC but they could be listed as "LOWER" and "UPPER" once you get the actual translation as well. In this case, they are different:

No.1 (RH and LH Upper) are part number SU003-02805.
No.2 (RH and LH Lower) are part number SU003-02818.
