A few years back I got a set of used Toyo R888s from Steved0x that were 225/45/17 in front and 255/40/17 in the rear. They worked well. I've since replaced them with Nitto NT01s in the same size.

There's some good tire discussion if you search that size for the front.

Thanks I'll go to 225/45 17's when the 17's are due for replacement, which will probably be due to age before tire wear! At my ability level summer performance tires are all I need on the track.

I've been spending my 'garage time' other cars and just driving Red for a while. A few issues have cropped up that want attention.
Running the Toyo track tires on the street has encouraged me to push the car a little harder. The extra stress finished off any support left in the engine mount. That does not feel good accelerating out of a corner. I'm sure that the center is completely detached now. I only have one good mount left on the shelf, so it's time to buy a couple new ones. Thinking of the Powerflex Polyurethane bushing.



The fuel gauge is starting to fail. It randomly drops to empty while I am driving. I need to pull the assembly out of the tank and see what the issue is. Not urgent, but important.

Urgent: The horn started going off at random times. Yesterday at a stop light it started honking and would not quit. There I was in the middle of town at a traffic light in my little red Porsche honking at 'everyone'. Finally, I grabbed the airbag and held it just right and the horn quit. It is not an uncommon problem on the old 4-spoke wheels. I fixed it last night.

The rubber bushings that mount the horn bracket wear out. The sagging bracket causes the contacts to meet and honk the horn.


With the bracket removed I filled the worn bushings with a silicone sealant and put a weight on it to reverse the sag while it dried.

Let us know what you think of the Powerflex bushing. I had a wevo in my street boxster and didn't like the interior noise it created.

I replaced the engine mount today with the Powerflex poly bushing. It was easy to assemble after pressing out the old bushing.


I was really impressed with how bad the old engine mount was. It was bolted to the frame with the wrong fasteners, missing a bolt on the engine, and completely worn out. I was fortunate to have all the correct parts on hand to reinstall it correctly.



Powering out of corners it felt wrong, but I am truly embarrassed that I drove on it as long as I did. Of course it feels a lot better now. I'll report back in a couple weeks how it compares to the standard mount.

This is really a great thread, your abilities are impressive.
