I've always wondered how much play there is in the ND1 Miata suspension bushings - which turns out to be quite a bit. Recorded at the Houston SCCA event - come race with us! ontheledgeracing
I was also surprised at how much it moved, could it be worn? I wonder if you fitted polybushes and did the same video to see how much movement there is with them. Great video thanks
The deflection that keeps other parts and tires last longer. Rubber bushes meant for road use not meant for precision use / track performance. Do not change to harder material.
This is really valuable information. Thank you. Really highlights how much it is a shame that Mazda doesn't have a performance division. This is the type of stuff that typically gets tightened up on Type R's, M's, AMG's, GR's, etc.
@@fakename287 no, because they need to keep the noise and vibrations down, for comfort. but for example, bmw m4, m2, m3, m5 (the new ones) have the rear subframe bolted directly to the floor, without any bushings.

The bushing deflects more than I expected. Cool video.

time to replace them with delrin and poly ;)

Especially considering that the pivot bolt of the rear bushing is used for camber adjustment (since there is an eccentric washer).
props to the cameraman for being so brave!

for a second I was like where is the drive shaft...
that's when I knew, I f*cked up.
finally understood how anti-roll bar actually works! thank you :)
Looks to me like a totally independent front suspension, without anti-roll bar
@@tomasnokechtesledger1786 The anit-roll bar is right there beside the shock.
@@ian3166 Well, Looks to me that's a multilink on a McPherson strut, isn't it?
@@tomasnokechtesledger1786 The ND is double wishbone, not a strut. That anti roll bar isn't attached to the shock.
@@ian3166 Are you sure? AFAIK Double wishbones are used at rear suspensions, I'm affraid. What's ND?
WOW I congratulate you for this well thought out video
Very interesting to see the interaction of parts...
Love the video, thank you for sharing.
damn havent seen bushings move like that before, pretty cool
That is insane howuch movement there is in tyre bush everything
What is steering the tyers. Man i am loosing my mind.
Most satisfying video
Lastik, süspansiyon, salıncak ve yol reaksiyonları; interesting, interessante, enteresan. Slalom ve yol kavrama test. Otomobilin altından🤔🤔🤔🤔
It's some what satisfying
rear wheel drive?
Yup
What is the tire size? Thanks
245/40R17 on a 17x9 +45 wheel
you need poly bushings
stiffer is not always bettter
@@Alniemi when it comes to spring rates, yes. But soft bushings dont keep the alignment correct when under load
@@freedomlifemake2579 then manufacturers (especially high-end ones) would be using poly, no?
@@fakename287 no, because they need to keep the noise and vibrations down, for comfort. but for example, bmw m4, m2, m3, m5 (the new ones) have the rear subframe bolted directly to the floor, without any bushings.
покрышки не в ту сторону обуты!
Всё там правильно. это зеркальный эффект
