WhiteLine or PowerFlex bushings?

Well...
Its important to know what position on the car the bushing is going to be used in. Bushings mostly go in control arms (duh).
One company's bushing design may work better on a certain position in the car.
For example: I think powerflex makes a compliance bushing that uses a polyurethane ball. That design will work better than other poly types. That design doesn't carry into the other two front LCA bushing spots. Maybe whiteline has a better design for the other two spots....maybe not.
People often replace only the bushings that need replacement.
Worth noting....poly bushings are mostly junk....
But...I do like that powerflex bonds the bushing to the sleeve. Not sure how resilient poly is to tearing/stretching/seperating in comparison to rubber.
The Honda factory bushings are very well made. I am hoping you're making this swap because yours are worn out. If they're not worn out...I would suggest neither brand.
Another company to consider is hardrace. They make decent rubber bushings for cheap.
I have bought (but not yet fitted or driven) their pillowball compliance bushing. Their pillowball stuff seems nicely made, they all have protective boots...and they're also fairly inexpensive.
A metal/ptfe spherical (pillowball) bearing is probably the best overall choice for many of the bushings on the car.

uhh... I never noted any red bushings i was going to use, the only ones i can think of are energy suspension and i hear they are like 95A, Powerflex is 80A and whiteline is 75. Spherical will be extremely harsh, probably worse than ES 95A. Not looking to track every weekend but enough to where i can possibly take it there so i believe i'll go WL. I do not need race, i do need something better than OE. I felt Whiteline is best since i hear great stuff about them and their different design of bushings. They are also cheaper from what I've glanced over. Powerflex is just a tad stiffer i guess you would call it? I would never go ES, not planning to race and PF also makes a 95 durometer.

New addition for Whiteline apparently. Previously, they only had stabilizer bar bushings. They need to sort their offerings out though. They list the same part number for the rear upper between both the AP1 and AP2 and those are different sizes. That alone would make me hesitant to go with Whiteline since you can't verify which set of arms it is for. My money is on it being sized for AP1 rear arms.
PowerFlex has different part numbers for AP1 and AP2 rear uppers.

that's not true if you're buying the right parts....
Well made sphericals last quite a while. Your ball joints last a long time, don't they?
If you're worried about NVH and lifespan and street use, why are you considering poly at all? They're the least steerable bushing joint.
Think about this...
OEM's use either rubber bushings or spherical bearings in control arms. Nobody uses polyurethane.
To answer your question, I'd use a compliance bushing that acts more as a bearing. For the other control arm bushings, I'd (semi reluctantly) buy the brand that uses a bonded type rather than a floating type.

Whiteline Suspension Bushings suitable for HONDA S2000 AP1, AP2 (8/1999-2009)

Let me know if you confirm as i am interested but i have a feeling these would only be for AP1. Australia like the UK only got the AP1 chassis.

I'm kidding, I talked to Whiteline and they confirmed the rear's are different but couldn't tell me which year so i went on PowerFlex's site and look up their notes for S2000 bushings and found that 2004+ used the 42mm and -2004 used 35mm OD bushings. All the bushings they listed are available for Ap1's, Problem is only for AP2's, they did not list on their site for the rears but gave me the P/N: and i looked it up on their site and its W63444 is the 42mm OD and W63443 is the 35mm OD. Everything else is fine. If you need compliance bushings, I'd probably go with Powerflex since they don't list any on their site and shock bushings and so on. So to conclude so nobody gets confused after reading this. Whiteline lists the AP1's on their site but if you search for W63444 its for the AP2, just replace the W63443 you find with that and you should be good.

Really? Are you sure? For street and casual (not competition) track, stock bushings work great.
So at what point do you need 'better' than stock bushings? Lets assume for this conversation better means less deflection. Until you are generating cornering (or braking and acceleration) forces that cause significant deflection of the stock bushings, the stock bushings will work perfectly fine.
If you are on street tires, or your springs are less than say, ?700 in/lb range, you can't be generating such forces. Replacing bushings is only going to have an affect on nvh, and not give any appreciable performance enhancement.
The stock bushings will also outlast anything else you can choose.

They have engineered their bushings alot better than PowerFlex. PowerFlex is just a bushing thats either purple or black w/ higher or lower durometer rating. Doesn't have the special characteristics of WL's. I do care about deflection, that'll make it handle alot better than oem. From what i heard, as long as you keep them lubricated the noise should not be a problem. Vibration and harshness cannot be said though. The bushings should literally lubricate themselves from what i've read too. I really don't agree with you on the last comment, OE will last couple years, Poly bushings should last the life of the vehicle. I feel its going to be worth it. Also can't beat lifetime that lifetime warranty. I do appreciate your opinion though. Thanks. Always willing to have a conversation.

Poly eventually degrades, then deforms, then degrades much faster. This is especially true if its not kept well lubed. The lube is very sticky, so if used in a dusty environment, will attract grit which will act like sandpaper, abraiding the bushing.
Rubber bushings have proven to last over time.
But you're set on trying it. Which is fine. I wish you luck with it!
