alignment

[mustangtomiata]

I am getting an alignment soon, what is a good street setup that works well at the track and autox? from experience, I get really bad camber wear in the rear...discuss and give me the advice from experience.

I ended up with a slightly more aggressive version of the Lanny's alignment from m.net. I'll try and find the print out and get it up here. Or actually, I think I ended up with a less extreme version of what Matthew said he used in the autocross alignment thread.

you probably ended up with toe wear in the rear, not camber. 1.5* all around (or 1.5 front, 1- 1.25* rear) works well. For a street setup, get about 1/16" toe out front and 0 toe rear.

You go for more camber in the front than rear Andrew?

I do too. -1.3 R and -1.8 F with 0* toe all the way around.

I think have -1.75 rear and -1.5 front

absolutely

you guys should all considering dialing in a half-turn of toe-out on 1 of your tie rods before events. It makes such a huge difference in turn in response.

I'm also running 1/16" toe IN in the rear. Really helps keep it stable. The car slaloms like woah.

I think have -1.75 rear and -1.5 front

You generally want to have a lot of rear contact patch as you want the tires to be able to push you out of a corner, not spin. The fronts obviously do the cornering, so they'll need a little more.

Makes sense. Now I really wanna see what I've got going on.

ive always wanted to do it myself, i used to be able to eyeball my old trucks suspension back into spec when swapping out parts

We're going to be building a few stands to do it on the miata early next year, along with ghetto fabbed slide plates

I run around -1.25 up front, and -2.2 in the rear, with toe zeroed out (or as close as it can) all around and as much caster as I can run without detracting from camber. Seems to do alright, no abnormal wear.

what's your suspension set up? That seems like it may be less than ideal...

[thx712517]

Your normal C-Stock setup. Stock springs, Koni off the shelf shocks, Racing Beat front swaybar with the Mazdaspeed mounts and adjustable end links. If there's more grip to be found in the setup please let me know, I've gotta put an end to Sam Mobley's domination of C-Stock in 2009. All I wanna do is crack into the top three....

what is the car doing? Different setups work for different drivers lol

[thx712517]

Car seems to be doing just fine. I got my best times (when running very old V710s) with 24 psi up front and 18 in the rear, with all shocks at full stiff. It'll understeer bad if I push it too hard, but just about any car will if you screw up your braking point. On the street with all shocks at full soft on my RE-01Rs it'll haul balls, but the front end will start to wash out a bit if you push it too fast in tight corners.
