I would like to go with Minilites for the front and rear of my 914-6 GT project. I am considering the Mag style with 7X15 fronts and 8X15 rears. I would like to pair these with the Michelin TB15 tires. The sizes would be 18/60R15 (215/55-15) front and 23/62R15 (270/45-15) rears.
Anyone have experience with this combination on a GT clone? Will I require spacers on either the front or rear? |

Getting back to tire diameter...The stock 914 used 165/80-15 tires which had a diameter of 25.4" The Michelin TB's I am considering would have a diameter of 24.5. That would lead to a 3-4% error in Speedo reading. Doesn't seem like much to me.
Who looks at the speedo anyway? |

It’s not just the speedo, but the shorter the tire, the higher the revs at a given speed, which can be annoying on the freeway and wasted gas. However 3-4% error will be negligible anyway for all the above. I’m also a fan of GPS speedometers. No bouncy speedo and always accurate. |
