I have them on the '86 SDL. Put about 15K on them to date. They are perfectly capable in terms of wet and dry traction..........not the greatest in cornering capability.............and poor in terms of the noise factor. They make a high pitched scream on most pavements............even some asphalt. If you sensitive to noise..........avoid them.

I decided to try the Pilot Exalto A/S for the SD instead of the Hydroedge. We'll see how it goes.
