Alignment Specs Question

[CoryM]

Probably not much help but I'm running in HS so set camber to the maximum legal spec (-0.92° iirc). Tire's are wearing reasonably well from autoX so it probably doesn't need much more for a mild car. I haven't fiddled with toe at all.

Someone must make a camber/caster plate? If not they aren't hard to make. Some measurements and a local machine shop should get you sorted. I love lots of caster in RWD cars but have never played with a FWD before.

Is .92 all you could get out of the Toyota crash bolts? The rules limit the method and parts you use to gain camber, but the stock class rules do not limit you to max factory spec.

Well, I asked and was told to keep it w/i the stock specs. The 2012 rulebooks reads:

" Both the front and rear suspension may be adjusted through their
designed range of adjustment by use of factory adjustment arrangements
or by taking advantage of inherent manufacturing tolerances.
This encompasses both alignment and ride height parameters if such
adjustments are provided by the stock components and specified by
the factory as normal methods of adjustment. However, no suspension
part may be modified for the purpose of adjustment unless such modification is specifically authorized by the factory shop manual for
non-competition purposes.

Unless I am missing something, the bold part means in stock class one needs to stay with in the stock specifications.

Doesn't really matter as I think I only have one more event in HS. After that it's STF.

Cheers.

You should have kept reading :
13.8.E. 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. If enlarging
mounting holes is specifically authorized but no material removal
limits are specified, material removal is restricted to the amount necessary
to achieve the maximum factory alignment specification.

Order the smallest set of Toyota bolts for the Yaris and max it.

Not sure how I missed that... besides being tired and stupid. Thanks.
I didn't really look too hard at the Stock rules last night to be honest. Was more interested in STF rules. Trying to not spend money on the Yaris (daily driver) and get the project car done instead. Not sure what I would throw at the Yaris besides tires and align. Maybe a seat so I can left foot brake (instead of using my left leg to brace myself against the door). And lighter wheels... and.... arg!

Cheers.
