I always wonder about the price to do these modifications/repairs in y’all’s videos. Would be super cool for the non-car-expert viewers if you included an estimation of the prices.

[@GearsandGasoline]

I meant to say it in the video: Used RX7 Case/RX8 Diff/Seals - $6-700 w/ shipping from eBay/Racing Beat ATS Super Silent - $1600 w/ shipping RP Diff Brace - $425 w/ 2 day shipping So like $2700 all told. I don't know about Jon and Aaron's pricing for services like these.

Let us all just take a moment and appreciate the craftsmanship here. When someone asks “why is that so expensive?” Many times it’s because there are men who have put in the time, sweat, and blood and know for a fact what they are doing through and through. This gives me a weird sense of comfort and appreciation. And I’m the weird guy who watches every Sunday and knows little to nothing about cars. Great content guys. One day I’ll have something besides my 2003 CRV lol

Dang! You properly destroyed that diff. When mine went in my 02' WRX I was on the freeway. I was doing some "testing" against a Charger. I guess the diff just overheated and bang! Sounded like a 12 gage went off in my car. The broken gear teeth exited through a large hole in the case.

@7:28 - just how much blood did he get all over this diff?! This video was well worth the wait - extremely informative for me as I don't have any differential experience (from a rebuild perspective)

[@ericmueser]

This G&G video had it all. ASMR, educational content, carnage, and christening new parts with donuts.

[@rotaryperfection]

The secret to not grenade an FD diff is PRELOAD the drivetrain before launching. The inner torsens have a bit of slack which allows too much play with the drive shaft. When launching without loading, you're basically impact/jack hammering the internal torsen gears as the driveshaft will free spin a little bit before the gears engaged internally. Preloading seats all the gears.

[@dack981]

I’m relieved to know I’m not the only one with an ATS “super silent” that isn’t exactly what I would consider quiet, let alone silent haha. It’s held up to some pretty hard abuse in my FD, launching at the track on drag radials, so I think you’ll be pleased!

[@54M0HT]

An excellent vid, albeit one that might *perhaps* give viewers the impression that FD diffs are fragile. Having had mine for nine years and done a few trackdays, I've not encountered any diff problems nor heard of it being an issue outside of big-power drag cars. It's important to remember that the RX-7 is a quarter-tonne lighter than most 276hp-class rivals, without using any exotic materials. You don't shave that kind of weight by making anything thicker, stronger or heavier than it needs to be. As a piece of precision engineering, most parts of the FD are strong enough for normal enthusiastic use; however they don't have the extra margin for "abuse" in the way that a Mustang or Camaro might. That's part of the tradeoff for a lighter car. Don't worry, I understand this is KZbin not real life. You made an amusing video breaking the diff, and now you've made a really informative and enthralling technical one replacing it with an upgraded part that'll stand up to burning out sticky tyres. So yeah, not a complaint at all, love the channel - just want to put the 'weak' diff aspect into context for other viewers 🙂

[@ScootLanguage]
