I have a 2019 370z sport 6MT that had 19" Bridgestone Potenza S007 tires as the OEM fitment. I put the Hotchkis anti-roll bars and a set of Michelin Pilot Sport Cup 2(240) tires on the car and immediately noticed a big improvement in the handling, with a moderate increase in ride harshness.
How does changing the sway bar increase ride harshness? I was looking at upgrading my 2013 G37, and it has the 18" Michelin Pilot ZR tires on it as well, but I don't want to decrease ride quality. I wonder if there's a difference in ride quality between a lowered one and stock height springs/shocks. I use to have a 96 Integra with a +2" drop, 17's, and that significantly increased harshness.
@@ptinker106 With no sway bar, each of the wheels on an axle are independently controlled by that wheel's spring and the stiffness of the spring is constant, with ride harshness governed by how stiff the spring is. Adding a sway bar, a torsion bar, to an axle links the two wheels so that the bar acts as an additional spring in parallel to the wheel's spring. This is if there is a difference in deflection between the wheels on the axle. If one wheel hits a bump but the other remains fixed then the bar twists and resists the deflection, adding to the spring that's resisting the deflection and effectively increasing how stiff the wheel is, transmitting more of the impulse of the force through the suspension and the rest of the car, what you feel. If both wheels experience the same displacement then the bar just rotates, not exerting any force on the wheels. Putting a thicker, stiffer, sway bar increases the amount of additional force a wheel experiences when there is a differential displacement on the wheels on an axle.
looking to get lowering springs and sway bars on 2016 q50 3.0 awd. With my 20" wheels and stock suspension the ride seems on the stiffer side-- will sway bars and or lower springs make it to stiff? And do you know the average shop installation cost? looking to improve handling and have lower stance.
Sway bars won’t impact ride stiffness but lowering springs will. If it’s already stiff for you, then it’ll just be worse with springs and much worse with Coilovers
There is no reason that you couldn't mix and match if you wanted to. To me, the difference in stiffness for the rear sway bar is so minimal that id prefer to keep it the same brand front and back, but yeah definitely can mix and match.
@@akashchahal5894 I mentioned that in the video. 2016+ Q50 for aFe sway bars. You’d have to ask them if they fit the older Q. I don’t know why they wouldn’t but I can’t be certain.
im sad that you didnt address the roll bars acting together as a set. you cant base your opinion of how well a set is just because the front is stiffer. a stiffer front bar DOES NOT MEAN it will turn in better. you mentioned the Q50 being nose heavy (as are most cars). you denigrated the AFE roll bar because it wasnt as stiff up front but failed to understand the the rear bar, with its adjustability, can be stiffer out back. this actually means the AFE roll bars would actually allow a Q50 to dial out understeer BETTER than the hotchkis roll bars. lastly, you never even touched on how the car actually handles on the different settings. perhaps if you did, youd better understand WHY the front roll bar on the AFE set isnt quite as stiff as the hotchkis bar. for a front engine, rwd car, the closer the rear bar is in stiffness in relation to the front, the more it will trend from understeer to oversteer. the is the same reason fwd cars have HUGE rear roll bars, to get the rear to turn.
Obviously most cars are nose heavy-the point being that the Q50 acts as if it is significantly unbalanced with a major forward bias. This is not my first sway bar video-it was not a full review of the hotchkis sway bar, so no I did not go through how the car feels with every setting. I’d agree that stiffer in the front does not “always” mean better turn in. However, I would say that the Q50 could stand to have an even stiffer setting in the front. With the factory front sway the car wanted to push through the front tires on tight turn ins. The stuff hotchkis cleaned that up significantly. I have seen some Z cars in track move back to the factory rear sway bar but they have their car nearly 50/50 balance with significant weight reduction and redistribution. None of this changes the fact that you’re putting an aFe sway bar against a hotchkis. I don’t think hotchkis blindly came up with a random number for the front.
@@SpeedCultureStudios going too stiff up front in relation to the rear will show up as understeer (duh) but also shows up as reduced wheel articulation and finally as uneven tire temps and wear. too stiff front and rear will show up as a twitchy mess of a car that hikes the inside rear tire (on an irs car) or unloads to inside rear tire and needlessly wears the lsd in a stick axle car. its a balancing act thats full of compromises to be sure. thanks for the reply, i do enjoy your content and ive closely followed the Z1 diff brace install. imo, its such a huge step up in quality and engineering over other designs.

I'm glad I went with Hotchkiss sway bars and spl end links. Easy to get on and definitely feel the difference.
Why did you add the Spl end links ? How has it handled over the year?
Best brand you can buy for durability. To answer your question, after having them on for 3 years. They're doing fine. No issues.
I have Stillen front and rear sway bars and yes they’re adjustable

I love your content for upgrade components on the Nissan Q,G and Z cars.
Thanks!
Would you still pick the hotchkis set over afe for the q60? And spl end links? Thanks
Yes. Sway bars are hotchkis’s specialty.
I'm going Hotchkiss. Still on back-order though. Been waiting almost six months!
That’s a long wait! Where did you purchase from?
@@SpeedCultureStudios Jeggs
@@tykedogtyke did you try concept z? They’ve been great about having hotchkis in stock
Have you made a video comparing stillen to hotchkis?
I don’t think so-not specifically comparing them, but I did talk about their differences in one of my sway bar videos I believe

If you were to do either the front or rear sway bar only on the 14 q50 awd…which one or don’t bother unless doing both? Thanks 😎
Rear. The awd already has a pretty solid front sway bar
Thanks just need to find a reasonably priced one in Canada... 🤔
What brand and tire size you have ?
what about hotchkis on the front and afe on the rear

Do u think a muffler delete and test pipes sound ok on the 3.7 I may get that bc it’s cheap and can’t rlly afford a 1k exhaust like ark
No it sounds terrible. Very raspy. Check out my exhaust videos!
