Interesting to see how much the diff moves on shifts. Lots of sidewall flex too, but as expected.

very cool, thanks for posting that

I’m glad you guys enjoyed the video! I welcome your comments and suggestions on my blog. Do you have an idea for a cool video experiment? We have other videos we have shot that are in the pipe to be posted, and we have other experiments we want to try. Stay tuned!

ive been thinking of doing something similar, but to diagnose a problem. ive got what seems to be a ront suspension binding problem as im getting a lot of inside wheel life unlike any of the other racers at the same corners and so i was going to put my gopro in the airdamn looking back at the front suspension, also itd look cool if i got sideways to see how fast i can move the front tires around haha.

Also, very cool and surprising video, i had no idea the diff moved so much, what kind of bushings do you have back there?

Yup! We have a video just like that (a camera under the air dam looking at the front suspension) that we’ll release soon.

That rear suepsnsion has an OE rubber diff mount, Ireland subframe mounts and Ireland RTAB. We’ll be making some changes to the bushings and repeat the test.

wtg Carlo. Vy nice.

Nice video. It will be interesting to see the movement differences after the new diff bushing is installed.

Thanks for sharing.
