I have a new set on my 2002 C4S as well. I replaced the same type after 8,000 miles. They work hard and are a great value. Fronts were 50% but changed all of them for a good match. Blew the rear passenger without any wheel damage due to a pretty solid sidewall.

Could not find the rears anywhere but online.

I will probably buy them again unless something better comes along...

I have used them on my 99 Boxster. They have been great. I've also the HTR IIs.

 

I have Michelin Pilot Super Sports on my 2000 911. Once these wear out I am going to HTR IIs or HTR IIIs.

 

Just my two cents

After much research, I just bought a set of HTR ZIII for the rears. Research seems to point to them being very "sticky" and  very predictable as to how and when they "break traction".... My only fear is that they look/sound like "squealers" on the videos I have seen. I prefer a tire that is rather quiet when it spins/slides. 

Too early/cold to bring the car out as of yet so have no personal experience with theses to share yet.

If I like ...I shall scrap the yoko fronts and match tires....as is safest.

 

Price vs reviews= A+... definitely a good tire to be considered.

 

The only negative I have  so far (and something known to me  going into purchase) is that there is an inside and outside sidewall-  so it is asymmetrical....yet the thread looks but is not considered directional.... the inside thread is cut in a curve....so it kind will look OFF mounted on vehicle.

 

My last tires were directional but not asymmetrical....so my adjusted negative camber would wear them out inside .....and then to even them out ....I would dismount and mount them on opposing side rims (a labour intensive rotation). Not a possibility with these as the out has to remain out.....so be sure to retain factoty camber.

 

 

PS: Loren....noticed you are running much wider tires on a NB C2.... may I ask what width rims, offset (or BS) you are running and if your fenders are stock.
