First off awesome writeup!!!!!!!!!!!

I have one question though, for those looking to stay in HS what shocks/struts work well with stock springs? Any side affects with that combination?

Most are designed to be paired with lowering springs so it seems like this would affect their range of motion (I need something that can go over potholes). Of course if anyone knows of reasonably priced adjustable ones let me know.

i would imagine that the TRD shocks would fair well with stock suspension, since TRD is for their mild 1"ish drop.

R comps will take you a lot further than shocks in HS though IMO

also, keep in mind, if you run a "shorter" shock with stock spring, you'll be compressing the stock spring beyond its original setting, thereby raising your static spring rate :D which isn't bad, but may get you kicked out of HS in a nationals environment. (not that an HS mini is gonna be scared of a yaris.......... )

Hmmm... in SCCA stock class, you can't change the springs or alter the ride height. Dampers are otherwise unlimited... Hmmm...

Seems to me that you could get a generic race shock to replace the rear shocks on the Yaris pretty easily. It's just an eye at the bottom and pin at the top, very common configuration. Get something that you can dial in really some really stiff compression damping for autocrossing and it should do a world of good for reducing understeer.

That, plus maxing out the front camber, and the tires mentioned above... that should do a pretty good job of challenging the competition.

footnote: One of the caveats of the "shocks are free" rule is that you can't alter the spring perch height. Since the spring perches aren't part of the Yaris rear shocks... you should be free to replace those rear shocks with ANYTHING.

..... and getting the yaris to rotate is by far the most important thing in stock class :D

it's a shame you won't get any real camber out of the front though :(

I hadn't thought about that, sounds like I have some measuring to do before May.

I've looked at the rear shocks and it does seem pretty easy get a shock that fits, Radflo makes a GREAT race shock and they'll make shocks to your dimensions (collapsed and extended lengths) I've ran several sets of their shocks on my previous trucks. The front would be more of a task considering the mount from the strut to the knuckle would have to be figured out. 2.5 inch diameter race shocks on all 4 corners of a Yaris would be fun (well maybe 2.0's would be more reasonable haha)An External reservoir or internal floating piston shock would be nice.

Question: How would 10mm rear hub spacers affect handling?

Wider track usually means more grip (for various reasons). So, widening the track in the rear would make the rear stick better. Not really what most of us are fighting for, with a FWD car, you want more grip in the front.

The rear hub spacers are purely a cosmetic mod. (not to be confused with alignment shims)

ah, thats right... i remember a friend of mine use to use them on the front when he would autox (SE-R, fwd).

im still working on this shocks thing, i have to turn in a research proposal this week and its consuming all my time! :(
