Sure do! It made a huge improvement in the car. Other than my VMP setup it is probably my favorite thing I have done to the car. I heard the solid steering rack bushings make a huge difference as well.
They most certainly do. Before I went with the tubular K, the solid bushings on the stock K we're one of my favorite mods as far as suspension goes. It was very noticeable.
I think these days, every SN95 could benefit from a solid shaft and steering rack bushings. SN95s are now 18-25 years old.
