Slicks tires 17


Happy new year.

Will be running this Porsche 911 SC 3.0 1981 all Racecar in 2018.

The car is running 8x17 fronts and 9.5x17 rears.

Old tires:

As class rules we can run Slicks.

Please let me know your choice of slick tires.?

Thanks - Cheers - Olsen911 - Tommy Olsen

I guess you will want to run radial slicks to be more competitive and for better lap times.
I've had taller tires on the 911 but prefer shorter slicks, 25 rear, 23.5 front Avons.

Although I prefer bias ply for greater slip angles and lurid slides and saves.
I have 15 inch diameter bias ply Avons on my 911.
16 inch Goodyear bias ply on one non Porsche race car,
and 16 diameter Goodyear radial slicks on the other non porsche.

Don't bother with these cheap American racer slicks, they start off crappy and then get worse.

The "used slick" market consists mostly of the 18" size. I use mostly Pirreli's due to the choice of sidewall heights. These slicks come from Cups, GT4's and Caymans.
Meet the race shop folks at the track and pick up the next events tires.

PS, Formula Vee is your friend if application directions are exactly followed

Not as much choice in true slicks at 17", tons of 18's though. Call some of the race tire shops and see what they offer (Frisby, AIM, Roger Krause, Sasco, etc). I know Yokohama makes some 17's. Dunlop used to be available in that size but that was a long time ago. Probably be a special order thing. If you can't find slicks you can run Hoosier R7. You can also modify those rear wheels to be wider and open up your options, since they are only 9" now. Nice car. I remember seeing it at POC events.
