B4 servo saver

[NewbyStu]

I noticed last night that when I apply full lock and apply a relatively small amount of pressure I can straighten my wheels without the servo moving. I have read various things about the servo saver on the B4 lacking grunt but this is ridiculous. Also, it seemed easier to move under full Left lock than full Right lock.

What has everyone else done about this? I've found this http://www.apexmodels.com/gbu0-prodshow/AS9657.html. But is it going to be any better than the original spring? Would rebuilding the steering set/ servo saver do any good?

I have noticed my wheels twitching (if you know what I mean) when cornering so i'm sure this must be effecting the handling. Cheers
