Re: Koni Yellows vs. Bilstein Sports (gti415)
I'm running Koni Yellows w/ Neuspeed SofSport Springs and like the setup very much. I can't comment on the Neuspeed Bilstein setup but assume it is very similar. I would go with whatever is cheaper.
As far as adjusting the Konis. I got mine installed 50% F, 70% R. I've adjusted the F to around 75-80%. To adjust the fronts is simple, remove the the strut cap and use the supplied knob to adjust stiffness. I'm not sure how to adjust the rears but have read that it takes a bit more effort.
