Could you talk about performance fluids in general? It would be cool to know what fluids might be worthwhile to invest in, and why, for a street car. There is so much more science behind the options available today.
When its cold enough that your tires partially freeze with a flat spot on them (from parking, road feels real bumpy for no apperant reason), it's probably a good idea to take it easier on the vehicle. One bump and you can tell whether or not the suspension is functioning properly. Heck, if you dont sink down in your seat the same way, assume the rest of the vehicle is just as cold. Engine temp is just one piece of the puzzle, and one of the only parts of your car that has a built in, automatic, self heating function. (Idling for half an hour does didly squat for diffs and shock temps)
This makes way too much sense. We MTB race currently but use to Dirt Bike race and Road Road years back. Colder days we rarely hit the bump stop under braking. Warm days we would stiffen up front forks (bike stuff) and never realized it was the oil viscosity due to temps. Thanks for the video.
Hey thanks for watching! It's one of those things we didn't really grasp either, until talking to the shock engineers and now it's OHHHH SO SIMPLE of course
Great video! Really timely explanation for me on why both of my cheapo front struts blew when I took my car ice racing a couple of weeks ago. The ice was pretty choppy in places and it was very cold.
@@Teamoneilrally actually AWD car (helical front LSD and Torsen rear) with snow in winter feathering brake without lift throttle brings the rear out which IDK why and in all condition highspeed cornering with playing with the brake make the car more planted (this could be fake as it is only a feeling) I am not sure which LSD is triggered by left foot braking; hence the question above
Is this an Audi? Very interesting. One thing that happens when you LFB while on the gas in an AWD car like that is that it slows the front tires down more than the rears, because of the bigger brakes in the front and the brake proportioning. This allows you to make an AWD car feel more like a RWD car when you're on the gas and brake at the same time, it doesn't work in all cars but some Audis do it really well.
Superb video. I remember I heard in one place "dampers boiling", but not much more. This time I have learned so much about dampers temperature effects, thank you.
Suspension oils are usually rated, among the other ways, with a viscosity index: the higher the index, the less the viscosity will change as the temperature changes. Tipically, it seems to me that, for dirtbikes, the ones having a higher V. I. are the most expensive.
This reminds me of something i heard/read somewhere about some f1 car, think it was a Haas. Basically the rear shocks would heat up from the engine and significantly change the dampening characteristics, making finding a good setup for the car near impossible.
I think it was this years Ferrari that suffered that. It's the reason the sBinalla was that strong, a driver that prefers planted rears using an unpredictable setup.
Konis are a twin tube low pressure damper. Upgrade to hi pressure monotube bilsteins. They are even better when hot, after an hour in the hills konis stop damping
That would definitely depend what your application is The normal street bilsteins are great but not adjustable at all, are they? You're kinda stuck with whatever the compression and rebound are set at from the factory Which is never exactly right for your exact vehicle setup, tires, springs, ride height, surface, temperatures... You can send the Bilsteins in to get re-valved at the factory but that takes a while With Konis you can adjust for road conditions, temps, tires, weight, swap springs... Or just your own mood and driving style
Look at a graph of konis on a dyno, the adjusters are linear and don't do much. Use a temp gun on them, then drive for an hour and retemp them. They cavitate too quickly for me. Sure they are comfy and nice for an old MG or Alfa though
Would you guys ever consider testing the newish Koni Active shocks that supersede the FSD? It would be sick to know how well they do vs the Sport on the dirt.
How are JVAB's with regards to oil temperature in the cold, he always speaks of clubbie racers in scandinavia, is his stuff built for that or it for xratties in the PNW where dipping below 20F is rare.
What do you recommend for shocks living in Canada with very low temperatures over a few month. Just trimming to very soft or changing the oil inside? Is there something available like an engine block heater for shocks?
The motocross guys have some solutions for heating their shocks, but I haven't seen anything for cars. Basically the best bet is to adjust them and let them warm up as much as possible
If it is a big deal, you could get yourself a separate set of shocks for winter. Change your shocks when you change your tires? There are shops that do custom valving, and they could change both the oil and valving to perform properly in cold temps. And there are ice racing series--those cars may have custom shocks...
Are the shocks with orange springs the Bilstein Motorsport 46mm? Do you guys still fabricate them to fit Subarus, (specifically the gc models)? If so is the damping adjustable? Thanks, looking to buy some rally suspension thats not upwards of 7k and I only see Streetwise Motorsports make them but I'd like to support you guys!
They are the 46mm Bilsteins, we made a big batch a few years ago but not any more. They're pretty good, but not adjustable. You have to send them out and get the valving adjusted. I wish there were more affordable options for Subaru rally suspension. We run the Konis on everything at the rally school and they're great, but we keep it pretty smooth here.
If I knew this was gonna be the last video with Wyatt I would’ve savored it a bit more
What ever happened to Wyatt? Does he have his own channel now?
@@powderrida I dunno, and I never checked, but he does have an Instagram atleast
@@powderrida He runs his own small business now, he has some pretty cool stuff for sale

Can you guys do a video on left foot braking and whether it really helps load up Torsen diff at the corner exit?
In a FWD or RWD car?

Great video! I always notice A bit more of a "crashy" feel when it's real cold out. Make sense!
Superb video. I remember I heard in one place "dampers boiling", but not much more. This time I have learned so much about dampers temperature effects, thank you.
Glad it was helpful!
I never knew. Thanks for sharing Wyatt!
Thanks for the video, one less thing to worry about.
I love how you take the bull out of the fads and the industry!

MTB bikes it is very noticeable when cold/hot. Even big elevation changes are noticeable (lift access bike parks for example) are bad. Nice video!
Dirt bikes are downright dangerous when it's cold too

Can you make a video about vehicles that do almost everything? I would listen to you more than anyone else on youtube
Would you guys ever consider testing the newish Koni Active shocks that supersede the FSD? It would be sick to know how well they do vs the Sport on the dirt.
I dropped some in my E46 with springs from a 330Xi and it gave it substantial lift.
We need to try out a set of those, no experience yet but they look very interesting
Looking forward to it! I’ve watched all of your videos more than once haha, always excited for new content.
Awesome, thanks Cameron!
I would love to see a will it rally on a crown vic lmao, feel like it’d be pretty cool to see

That would explain why my shock top mount is seizing up on one side making it squeak when turning right 🤔
last Wyatt video ????? sad suspension noises

Trade ya a 56 f100 for one of those Fiestas 😅
the oil is thicker than a snicker in cold temps
