How loud do you think it would be with the stock sub frame bushings and solid diff bushings? I’m debating going solids for the best performance over polyurethane but if they are too loud like this they may not be the right choice for a daily.
It wouldn't be too bad. Full rear poly bushings and a diff cover brace (Royalty Performance makes a great one) would work perfectly. I don't recommend solid diff bushings with stock or even poly subframe bushings due to the inability of the rear diff bushing to flex with solid as the subframe moves. You'll end up shearing the diff cover stud off in no time. So my recommendation for daily\heavy street use is the poly diff\subframe & Royalty Performance diff brace :)
I purchased the isr solid bushing kit subframe/transmount/diff do you recommend using all the solid bushings? Or should I change the diff to poly. Also worried that I won't like sound transferring through the chassis from the diff whine. Not sure what to do need opinions. Daily drifter.
Anthony Civito for a daily I would still recommend the solid diff\subframe bushings. If you use the silicone washers provided in the kit you shouldn't experience this aggressive diff whine. I was an idiot and went without, now I'll be dropping the subframe to add the washers later down the road.
Yes 29 to i26 haha. Yes go for it! Feels so much better than stock or with poly. I recommend powered by max solid bushings. They are slip fit and way easier than the press in kind.
@@Blyatarina thanks my man 😎👍. How is the powered max solid bushing sound tolerance? If you still around or still have the Z and go to meets like cars and coffee and autoworks hopefully I'll see you around. I have a black 291 nismo Z
This is exactly how mine sounds with solid diff and subframe bushings and I DONT recommend anyone do solid for a street/daily car. Track only should be solid bushings
@@tony_5156 they say polyurethane bushings are best for a street car where you just want to increase the driver input . I’ve never tried them though because I went with all solid mounts. Which is definitely full race car and everything is really loud.
@@Blyatarina yes that part I do know but let us just say rear subframe and differential polyurethane bushings from either Z1 Motorsports or Energy Suspension would they need to be greased you think, some say yes but many say no???
@@DragoMusivini personally I wouldn't unless they included a packet of grease. I put ES in before and they were grooved on the inside where the metal sleeve rests inside the bushings to hold grease in them. But I don't recall Z1 needing grease when I did those a year or so later. None should require it on the outside at least
@@ab15891 lol sitting at a stop light after our track day at road atlanta gave me a headache from just sitting, but that may have contributed from the little sleep we had. im more amazed by him being able to shift quickly and smoothly now without any jerking motions, i want to copy his car
Dang.. that whine is mad loud though, but in a sense it sounds good to me, like you're supercharged. Lol. I'm pretty sure you get so use to it that you don't even notice it anymore huh? I've noticed my rear diff bushing done leaked out and I have the hop and it tends to sway left and right at times at lower speeds.
bman409 definitely sounds awesome but the noise is nearly as loud as my exhaust system! I'm more used to it now, however it's still not something that I'd recommend for a daily driver. As far as the hop\sway, the subframe bushings cause the sway, & of course a lot of the hop as well
// // I was just looking at my rear tires and they do look a bit worn, so I was thinking that it could be my tires causing the sway too. It's only at low speeds.
bman409 I'm still gonna call it your subframe bushings causing it mainly, but it could very well be tires. Stock transmission mount let's the trans swing a lot as well, I'd suggest looking into a Z1 mount there
// // I'ma double check my alignment as well. Would an alignment rack tell me if it's my subframe bushings? The car is an '08 and I just hit 81k miles.
So the solid sub frame and differential bushings cause the diff to transmit the whine into the cabin. It gets very loud as the car gets faster. I definitely wouldn't recommend for a street car.

Those gears sound crazzyyyyy
Mine doesn't whine like yours. Did you put the little rubber thing back between two little bushing and the car?

That turbo veloster moves!
I couldn't actually accelerate at all, otherwise it wouldn't have looked like that even when I had a stock engine
It moves when not going around a corner and when no one else is accelerating :D
Will that cause accelerated wear on the diff?
I don't see why it would, the bushes just keep the diff from moving
Is that whining noise coming from the diff? Idk if I should run poly or solid bushings..
yep from the ring/pinion gear. I would definitely recommend solid just use the rubber/silicone washer on the subframe to lessen the whine
Poly for daily car for sure. I heard that noise is annoying asf after a while in your daily

Ppl saying not to go solid bushings for street use... but i rly like the raw sound? Should i go for it?
F it your car if anything just go back to how it used to be if u don’t like it😂😂
A little late to the party but is this just the 3 diff bushings or do you also have the subframe bushings
All good this is with all solid bushings in the rear end. Subframe, diff, and the shock mount bushings at this time
Hey what brand gauges are those?! This things sounds sick!!!
gauges are Revel VLS, thanks, I have to agree!
//// it's fine. I installed my solid bushings and it's nowhere near this bad and I have no interior
Wow I'm pretty late but those road looks like Westgate area 🤣( Im from around the burg area). Awesome video I'm planning to do all bushing soon too

@@willharris2607 is the ride quality similar with solid mounts vs poly?
Wow all that whine is coming from the diff??? Sounds just like a straight cut gearbox.
Haha i thought the same thing until i found out about solid diff bushings. Imagine solid diff bushings and straight cut gears gearbox
What gauges are those
They are Revel VLS oled oil temp, water temp, and oil pressure
Do you have to grease the polyurethane subframe and differential bushings before install?
Depends on the manufacturer for poly bushings. Solid bushings don't require any lube

From personal experience in that car... Holy shit
does it sound godly good?

clu-clunk clu-clunk, I thought I messed up my solid bushing install because it clunked afterwards. It sounds just like yours, I guess that's normal?
Wannabe180sx yes its normal
@@MICVHmusic same here, been 3 years and it didn't move yet so...
hella annoying on roundabouts
thank u

It’s like a sequential gearbox whine
What gauges do you have speed oil temp and...?
It's oil temp, oil pressure and water temp from left to right :)
What differential bushings did u use
ISR subframe and diff
@@Blyatarina thanks for the reply bro
@@Blyatarina still have the whine or did you install the rubber washer??
@@datboi8140 sorrry for the late reply, but yes even with the rubber washer it whines
//// //// it's fine. I installed my solid bushings and it's nowhere near this bad and I have no interior
Did the upgrade cause the transmission to whine? It sounds sick.
So the solid sub frame and differential bushings cause the diff to transmit the whine into the cabin. It gets very loud as the car gets faster. I definitely wouldn't recommend for a street car.
@@Blyatarina it is the sound I yearn for!
The whine is bc the solid bushings in the diff or the subframe?
@@tonobicicleta6054 combo of both, one or the other wouldn't have the same affect
what gauges are those?
Oil temp, oil pressure and water pressure from Revel VLS
// // how did you install them?? Any tutorials??
