Problem is i dont want any more NVH so i would probably just do oem bushes.
....I didn't experience any additional NVH after fitting SuperPro bushes and I haven't heard any reports of others doing so. I drove someone's Ed30 a couple of months ago who had just had SuperPro's fitted and no NVH there either.
The OEM bushes are rubber and will deteriorate much faster than polyurethane. Also, the labour costs are the same whichever bushes are newly fitted. Plus OEM bushes can be a PITA to remove because of corrosion etc. Either way you would also need to have your car aligned.
I don't know the cost difference between a full set of new OEM bushes and a full set of SuperPro or Powerflex bushes but that would be the only extra cost. vRSAlex could probably give you a good price.
How many miles has yours done now, Rich?
