Re: What kind of Koni's (1997 Golf GL)
Koni Reds = Koni Special. These are the milder adjustable sport shocks for the Mk3. Not available for the Mk4, except for special order.
Koni Yellow = Koni Sport. These are the more aggressive sport shocks for the Mk3. These will ride harsher than the Koni Reds.
If you are adding sport lowering springs like the NS or H&R Sports, you should use the Koni Sport set to full soft (default setting out of the box). If you buy the Koni Reds, you should increase the stiffness almost to about halfway to control the stiffer springs.
Since you are concerned about ride quality, you should consider getting the shocks with milder springs like the H&R OE Sports, not the H&R Sport or the Neuspeed stuff. Also, you should think about just getting shocks by themselves.
