Great write up Raj and as usual great choice of mods that you do.
This is definitely on my list but really can't see me having time to do it at the moment. Its my biggest complaint of the e9s....the front end just feels unresponsive regardless of the spring/strut combo. I've tried both birds and bc coils and whilst they improve things it still does not give me the sharpness that I like. Seems like this mod cures that.
One question though...u mention alignment of the bolt holes being a pain. Would it be easier to remove and replace one arm at a time...so at least alignment of the holes doesn't get thrown out that much?
