2013 Scion FR-S Information Posted to TIS

[Jeff Lange]

If anyone has a TIS account, you can now read the repair manuals, new car features book, etc.

It's all loaded.

Neat.

You know what to do.

So what does the alignment proceedure look like? Any info on the range of adjustment that can be obtained?

[Jeff Lange]

I checked earlier, I'll look again.

The front is adjustable, you can gain adjustment by ordering lower bolts and using them to replace the top bolts. I'll check the exact specs.

There were a couple other pieces of interesting information that I came across during looking as well. I don't really have the time to upload all of it, but I'm sure someone will at some point (perhaps me, later, if nobody else has).

Jeff - thanks for the info. I have a standing request with my scion sales guy to get me a peek at the manual when available, but who knows when that might happen!

"(0°+/- 0.75°)" - Not sounding very good for scca stock autocross performance or tire life.

So that adjustment requires replacing the OEM bolts....that doesn't sound stock class legal?

For everyone else it's a must do ultra cheap modification IMO but it sounds like stock class autocrossers may be unlucky.

someone PLEASE get a PDF

You are replacing one OEM bolt with another OEM bolt. As long as the bolt you are using is 'offered' by the OEM, it is scca stock legal, and it will not be questionable at all with the procedure called out in the FSM.

[Racecomp Engineering]

It's OEM but for a different car (Impreza) is my understanding. Available from the dealership but not included with the car from the factory.

I'm admittedly far from being on top of these kinds of details on classing.

[Jeff Lange]

It's from the FR-S. It's the same as the lower bolt, and is intended to be used by Toyota/Subaru to adjust the camber if required (stock or not).

[Racecomp Engineering]

Ahhh so the replacement bolt is not a cam bolt, just a different size?

[Jeff Lange]

Seems to be, yeah.

The rules: http://www.scca.com/assets/2012_Solo_Rules_March.pdf
Specifically section 13.8 on pages 77 and 78.

"If offered by the manufacturer for a particular model and year, the use of shims, special bolts, removal of material to enlarge mounting holes, and similar methods are allowed and the resulting alignment settings are permitted even if outside the normal specification or range of specifications recommended by the manufacturer."


So as long as the OEM offers specific parts to be used to adjust alignment on a specific model/year, it is legal. That it is apparently called out in the FSM makes it even more clear.

Note that I'm not defending the rule as sensible, just pointing out the way it is.

I'm trying to get my head around this one...

If the additional bolt is offered by Scion as an alternative part for the 2013 FR-S, then it (and its resulting alignment change) IS legal for SCCA stock autocross for the FR-S.

HOWEVER.... if Subaru does NOT offer the same part within its part catalog for the 2013 BRZ, then the part IS NOT legal for SCCA stock autocross for the BRZ, even though it's a form/fit/function replacement?

For those of us wanting to autocross in a stock class, this is an interesting situation. These are the sorts of gotchas you wouldn't want to learn AFTER you'd bought your car.

I got caught in an analogous gotcha with an NC MX-5. Got the car to do some track days, only to find that the factory roll bar wouldn't qualify as roll protection... and it was quite some time before the aftermarket figured out how to do a qualified bolt-in replacement for the factory unit.
