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.
