Need some quick sway bar measurements
 

I'm making a spreadsheet to calculate load transfers for each individual wheel at a given lateral acceleration. I got most of the values from the Mazda press kit (CG height, roll center heights, and random other specs). However, I'm still at college right now so I won't have the chance to take any measurements from my car for the next few weeks.

Can anybody take the following measurement for me?

I need:

Front and rear sway bar arm lengths (perpendicular distance from the center axis of the bar to the hole where the actuator attaches). Doesn't need to be perfect, lol.

Distance from the pivot axis of the lower control arm (on the chassis side) to the point where the sway bar endlink attaches to the control arm. Need front and rear.

If somebody happens to have the wheels off of their car right now or happens to have the stock sway bars laying around and can get these measurements, I would really appreciate it.

Also, I'm using motion ratios (damper travel/wheel travel) of 0.752 front and 0.855 rear, which I got here: https://www.rx8club.com/showpost.php...1&postcount=42
Can anybody confirm these motion ratios?

Thanks.

they're in a thread here somewhere, I'm not posting them again

Is there a location for important data. Like spring rates, sway bar diameter and wall thickness or am I expected to read the 1500+ sway bar posts.

I have a NC Miata and want to upgrade the sway bars. The Miata site indicates that there are 2 sets- 1 marked with Red and the other with yellow. I would like to confirm that these are the only stock bars and that the softer bars are only used on the models with auto transmission.

Thanks.

PS. Your search is no worse then ours.

^Really? All ya gotta do is type in

Sway Bar Measurements...

BAM!

I will stick with this from miata.net

Now for the RX-8 "standard suspension, automatic transmission" bars, the fronts are 25.4 mm with a wall of 3.5 mm. The rears are 16 mm, but I have no information on the wall thickness. I just know that it is thinner than that of the RX-8 "sports suspension" bar. The color code markings on these bars is red or reddish orange.

The RX-8 manual transmission or "sports suspension" bars are 27 mm with a wall thickness of 3.4 up front. At the rear, like the Eibach/Mazdaspeed bars the diameter is 16 mm. The wall for the rear "sports suspension" bar is 2.6 mm. Color code marking for the "sports suspension" bars are yellow.

Anyone have bars -red mark- for sale?

I just found out that the Series II R3 rear bar is different than the Series II non R3 rear bar. Couldn't find any more information though. Just the part numbers are different. The front bars have the same part number. I'm not sure if it's the same part number as Series I front bars.


Just a side note...maybe we should start calling them zenki & kouki like the 2nd Gen RX7's.
