My son is autocrossing a stock 2005 Mazdaspeed Miata in E Street. Looking for suggestions on alignment numbers for autocrossing and the street. His track tires are RE71R 205/45R16 on 16x7 wheels. We also plan on installing a Eibach 27mm front sway bar.

Thank you,

Thank you,

Instead of specific numbers which may not pertain to your particular car, let me provide a link in the miata.net site, which IME contains the most information:
https://forum.miata.net/vb/search.php?searchid=16465831
As you process the information, you can get more specific and drill down to more pertinent data.

You can also get a copy of Keith Tanner's Mazda Miata MX-5 Performance Projects, which has a section on alignment and specific settings.

Finally, be aware that not all specs may be attainable in a stock NB, but one has to start somewhere and an 05 Mazdaspeed is a good choice.

Come back for further Qs.

Good luck and have fun!

Flying Miata Specs..... https://www.flyinmiata.com/tech/alignment.php

ôLanny's" Specs......... http://www.hummingbirds.net/alignment.html

Both highly respected.

I favor these specs from Brian Goodwin. An "NC" Miata is different than earlier models to some degree. ND's even more so. Be aware.

The link to Miata.net didn't work. What search terms did you use?

Josh Smith at Mazda Motorsports suggested the following;

Max front caster (6-7 degrees)
front camber -2 degrees
1/16" front toe out (total)
rear camber -2 degrees
rear toe in 1/16" (total)

What do you think?

Thank you

OK, try this thread. Many pages and opinions on setup from current ES champions, which may be good for perspective.

https://forum.miata.net/vb/showthread.php?t=541008

Above specs are usually effective for autocross. Toe-out can make front end "darty" over road surface irregularities.
Also, most NBs (1999 - 2005) will NOT be able to attain -2* camber, unless lowered or fitted with extended ball joints/offset bushings, both of which are illegal for Street entries. I'm happy to get ~ -1* in mine.
Caster usually being whatever the value is after equalizing whatever maximum camber is available on both front corners.

Are you planning to attend the Arizona Border Region (AZBR) event tomorrow? Find me (or avatar) if you're there.

The dual duty alignment has worked well for me. Not sure you'll be able to meet all the recommended parameters with Street-class parts limitations.

That said, my tire wear indicates that I still need more camber. Test, investigate, and make changes accordingly. The car will tell you what it needs.
