So, any reviews on the poly bushings now that some time has passed?

 

Yes, I got all the powerflex bushings on my car now. What a bitch to put in, but in a way it was fun. I absolutely LOVE them. The car is very responsive, and firm. Got rid of my cracking noise i heard to when i got on the brakes hard. Keep in mind my old bushings had 140k miles on them. I probably have about 9 track days on the car since the powerflex and love it. Worth the price compared to the rest out there.

 

powerflex adds up over $700 a set!
imo, id rather pay a little more for the mono ball joints from Asura...

Your definition of "a little" may need calibration.

Besides, the applications are not the same: powerflex is street-able, monoballs are not - at least not in any practical sense.

 

Sounds like a good option. Did you do the work yourself (how bad was it)?

 

why arn't monoballs streetable?

 

I am not 100% sure of this yet but I will be having Delrin bushings made for my car this winter. The guy said he would be interested in putting together a kit for our cars that he would sell. I will post more information if this becomes a reality.

I have the Asura monoball control-arm bushings and KW V3's on my daily, and it's not harsh at all. You feel each bump a bit more than usual, but it's not like the harsh feeling you get from going over bumps with really stiff springs. It's not jarring at all. I guess you could call it a more direct feeling.
I think the harshness has alot more to due with coil-over setting/choice than with the bushings. At idle there isn't any additional vibration like when you install stiffer motor mounts.

Mine are holding up great I'm getting close to the 10,000 mile mark, part of which was a roadtrip to Seattle from Salt Lake City, a couple of track sessions, and everything in between as it's my only car.

Asura warranties them even if they're street driven. I don't know how much the replacement bushings are once these ones wear down after the warranties up. I'm sure I'll find out in a few years.

Hope this helps.

Monoballs should be ok for street use, main issue would be wear.
10k is pretty good, more than I would think, and it sounds like you have many more to go.

I have Delrin bushings in an RX7, ride is great.

 

I was talking about maintenance intervals, not comfort. I drive 15k miles a year - that's just commute, any road trips or track days are extra. I'd be replacing/rebuilding these at least every year.
