Recommended Alignment Specs
 

Only mods are..
Racing Beat 1.125" hollow adjustable front swaybar
5x Racing 14mm adjustable rear swaybar
205/50/15 POTENZA RE-71R tires
15x8 Enkei RP-F1

The alignment settings offered at 949racing.com for a street miata are as follows...

>=5.25" front pinch weld height

Front camber: -1.4°

Caster: >4.5°
Front total toe: 1/16"

Rear camber : -1°
Rear total toe: 1/8"

However, they stated that a 100% stock miata would be too "loose"

I drive aggressively, and have a lot of tight turns on the mountain roads around me. I would like a mostly neutral feel, and feeling "loose" doesn't sound like something I'm into.

Could anyone comment on what, if anything, they would change on these alignment specs?

Thanks,
Marcello

What 18 psi means to say is that this isn't the first time this question has been asked. As a member of MiataTurbo.net, you are expected to have read and memorized every single post which has ever been made here prior to asking a question, including the thousands which were lost when Philip massively fucked up the database during an attempted server migration back in 2008 and was discovered to have been too damned lazy and apathetic to have kept regular backups.

That said, the recommended specs for an alignment change depending upon who you ask.

Emilio (owner of 949) has alignment preferences which differ considerably from what was once accepted as common knowledge, in that he prefers to run more negative camber in the front than in the rear. For years, we all "knew" that Miatas handled best with more negative camber in the rear. That said, Emilio's recommendations reflect "serious" track applications and the use of relatively spendy coilover systems.

Personally, I like to run equal camber on all four wheels for street applications. On my last Miata, which was sort of stock-ish, I had good results on the street with -1° front and rear, as much positive caster as possible (usually around 4-5°, although this isn't critical) and zero toe. With sticky street rubber (Bridgestone RE-11 and Toyo R1R), this gave fairly even tire wear and well-composed handling without being too jittery on the highway.

Except if you actually search you'll see there are at least 3 pages of threads in which at least a handful discuss this very thing, all from 14/15.

I think OP just likes making new threads. Whatever.

run -1.5 all around if you want it "less loose" but still better than stock

I'm just dumb, when I search, I don't seem to find the answers I'm looking for, sorry I make so many threads.

just my opinion, but I'd prefer it more "loose" on the street than have it plow.

Believe it or not, but it is possible to get these cars to understeer, and it's terrible.

I was just about to say "the forum search kind of sucks, I find more stuff searching google for miataturbo.net results"

^Yup. What everyone else said.

Basically hop into a google search and do site:miataturbo.net "keyword"

You're running race tires with the stock suspension? Fix that before you fret over alignment too much.

RA-1 or R1R. No such thing as an RA1R

Updated first post.

I'll be waiting for the KBO 2.0 to get the FCM coilovers, so that's in the future

Off topic but don't use the stiff setting on the 5X (ST/KW) rear bar. We tested one years ago, binds and doesn't allow full droop in the stiff setting. Middle setting same rate as Mazda 14mm we use, soft setting a bit stiffer than OEM 12mm.

Again, I wouldn't obsess over alignment with your current hardware. It's not going to be balanced or predictable at the limit with that much grip on stock shocks. Max out front camber, run OEM toe, caster and call it a day until you can get some proper dampers and springs on there.

^ah ok,

Will do, thanks a lot!

LOL, I had this same question last week. I used google to search MT.net, M.net, CR.net and ended up taking notes from the 949 racing page. I trust emilio and he really took the time to write up some good information about which setup to pick. Google is your friend. The nice thing about the Miata, is someone has already asked the question and the information is out there. You just need to put in the leg work to find the good info.

Or you could get Xidas now

abso-freaking-lutely.
I wish I could +prop this post

Thanks, I do something right every once in a while.


I have to say that I love the Miata Google Database vs coming from the Subie world. It is fantastic how much information is out there.
