Kevlar Timing Belt

As someone already mentioned, the problem with these kevlar belts is that people think they are indestructible, and so they dont tension them right or leave them alone thinking they'll outlast the car. If you do end up going with that belt, be sure to tension it right, check it again after driving it a bit, then check it again just to be paranoid. While you're in there definitely do all the rollers, would suck to get a nice new belt on there and then seize a roller.

this kevlar belt may be the ticket for an experiment...build a non-interference engine (my next engine will be), throw the belt on and just check on it once in a while, and see how long it lasts

In that case, there's no way to really do this properly on 17" wheels because you can't get 285/30/17, they just don't exist. You'll need to either:
* switch to 18" wheels, or
* buy a compromise tire for the rear 17" wheels that will end up being 1" taller than the fronts. You can get several tires in 285/40/17. It seems like the best match is a Continental ExtremeContact DW or Pirelli PZero System.
I'm sure you can resell the Michelin PS2's, but the wheels would be a difficult sell. There just aren't many cars out there that would properly fit them, and some buyers might have concerns about mounting taller tires on the rear vs the front. It's always possible for CCW to modify the wheels ($$) by changing out the inside half (assuming they're 3-piece) so that you can mount a 255/40/17 - that way it would still have the same dimensions between the hub and the fender, it would just be further away from the inner wheelwell.

My concern is tire availability. When I purchased these wheels, there were a dozen tire choices in the the 255/285 combo. There are only two choices left, both MAX performance summer, a Kumho and a Continental. 11 months of the year I am driving on wet roads that are probably 40 degrees. The summer tires are too hard at these temperatures. My immediate problem is that the existing rear tires are 8 years old. They appear hard and dried out. I did not notice how bad the tires were until I put the Michelins up front and did a side-by-side comparison.
If the selection is this small now, what will it be like in 5 years? For this reason, I am thinking about doing the 18 inch upgrade.

Let me know how the experiment goes. I will have probably have gone through three belts before your results are in.

What type of impact did the cam make? I was always curious about what my car would have been like if I had installed it.
Would enjoy getting together to swap stories. Once I address a few more issues with my 951, I would like to start doing DE days again. Bill
