I've just ordered a set of these Whiteline bushes over the Powerflex ones as i have heard too many bad reviews of the latter.

If anyone is willing to cover shipping to the USA then you're free to have them. Perfect for a track car or use with softer diff bushes.

I recalled this in regards to NVH but haven't really heard of any other complaints from anybody replacing bushings other than using the inserts. After removing the stock ones and looking them over...I personally wouldn't waste my time with those as the 2 piece ones are just about as easy to do...you're only saving maybe 10% of the work/time...pointless IMO.

In regards to my car....I wouldn't say the bushings added any...I do think they may have broken in a bit after a few hundred miles...really hard to be subjective and conclusive on this. The car handles fine..still happy with it.

My biggest issues have been with power management...LSD is supposed to arrive next week but probably own't get that in until after the 1st of the year as it gets the remaining M bits at that time as well.

I believe it...when I did mine I started out following another DIY that said to disconnect the brake lines and remove the exhaust... after doing so and I started teh stock bushing removal... I went "WTF, why don't we just leverage the cars weight?"...a work smarter...not harder kind of thing. Given the urethane part of the bushings comes in 2 pieces...you don't have to get near as much clearance.


Just do it...and quit procrastinating...it's a pretty cheap mod for the amount of handling improvement you get out of it.
