I see that corrosion too but, according to my 200+ bushing dissembly experience, that corrosion isn't happening on every bushing. I'd say, 30% of them. and those are with cars that do outings in the rain/snow. I have a 360 that never goes into the rain and the insert (I called it the metal part) is like new inside! I am no pro, so I think I might benefit from your expertise, can we just clean corrosions and keep using them?
I’m happy to be talking with someone with experience and not just “keyboard knowledge!” By cleaning you introduce two major issues: 1. You’d reduce the diameter and as a result you’d induce slop. That would either make the suspension terrible, such as my current situation with worn Sphericals. The slop will also wear out the “bushing” much faster. 2. You might affect the circularity and cylindricity, which would also affect suspension in negative ways as well. 3. Lastly, one lesson I learned when I used to restore beetles and build rock crawlers.. when you remove rust or caked on dirt, grease, etc. sometimes you expose issues that were covered up. For example I cleaned 50 years worth of dirt and grease off a beetle suspension and when I reassembled it things were a bit off and I had a few leaks that the grease caked on was preventing. Counter intuitive but it’s happened to me often. Removing rust brings out pits. Those pits will now rust again and grow deeper and weaken the part more.
make sense. I understand that the polyurethane will last longer than OEM, but isn't it going to introduce some squeeking noise I installed some polyurethane bushing onto my 300zx and it squeaks sometimes
Correct. Poly will squeak. There’s a special grease used. That’s why I use a Teflon sleeve in my bushings so that there’s no Poly to metal contact. No noise or wear.
So do you use a grease or teflon sleeve or both? I hear the grease is a nightmare after a few track sessions picking up dirt.
Damn. I’m a bit late to this thread and video. Chris Harris made my day with two bold statements: “I’ll take the SCUD over the CS, Speciale, and Pista” “The world has gone bonkers. We need another Lotus Elise moment... a bit of power, get back to what driving’s all about” Been sayin’ this for years.

That's the issue I'm encountering currently while Developing high quality Spherical bushings. I think the issue is because Poly grease is so thick, it retains whatever sticks to it. Aside from Diffrential oil for Rock Crawlers, its the next worst lubricant I've dealt with. My parts have a tight fit, which helps prevent most debris. Aside from that, I dont use excessive grease. I wonder if there's a boot i can design for track users.
I'm totally with him on the "singular tone" of the Speciale's engine and on the speed/gearbox deficiencies of the CS. And to me the Speciale looks like a 458 with plastic surgery gone wrong while the CS is beautiful but the front end is a tad Hot Wheel-ish. Scud is the one. There is also something very special about the side profile of a Rosso Corsa Scuderia Coupe.
Interesting debate. Personally love the rawness, drive and sound of the CS. It’s the more visceral, Wild, seat of your pants experience. And yes, driven them all, except the Pista. All personal opinion at the end of the day regardless.
It's great to see them all together like that. What a collection! I noted the lack of confidence in the 430 Scuderia's brakes which made me raise an eyebrow. They should actually be around 20% better so I'm sure something wasn't right. This feeling of lack of stopping power can be caused by numerous issues not to mention poor running in of new ccm pads or not enough high speed stops to remove glazing. Maybe too much driving around at low speeds. I've also heard of quite a few different Scuderias which suffered from poor braking and they had to have replacement ccm master cylinders. Maybe a faulty batch? One of my friends experienced exactly same issues. In any case the braking performance should be more than excellent on the Scuderia if its performing as it should. I also found the RS19 and RS29 pagid compounds work really well on those stoppers. Not to mention using good fluid like Castrol SRF. He may also be feeling weight differential between the two sample cars too, again varying specs can make a huge difference here. And then further from that the condition of the tires too. Endless variables make comparing so damn difficult! The performance is definitely quite a bit quicker but not as much as some on here think. I would again estimate around 20% differential which makes its presence felt more above 100mph so again in give or take driving with friends in convoy you may not appreciate diffence quite so much. Obviously you could argue both ways that it's a big difference or not such important however it's performance is totally eclipsed by modern post 2012 Turbocharged era cars anyway by significantly more than 20%. Is that important? Not really. They are still plenty quick enough out on the road. If your jumping in and out of different much higher performance cars you concentrate on the experience too, not just outright grunt on straights. I felt a very good point came out too with regards to overall lasting impression of driving both cars. That is the Scud feels more like a polished road car that's been made to feel sportier. The CS feels more akin to an old challenge race car with stiffer setup, noise, angrier, snarlier and much less polished overall. Drive a real challenge race car and you'll appreciate it's actually on a whole different level again but it's certainly up there as an road car experience.
Lost all credibility when he complained of the brakes in a scuderia. That’s much improved over the CS Sent from my iPad using Tapatalk
