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?

270/45-15 tires are going to be way too short for street use. Unless you change the ratios in the gearbox, you are going to be spinning the engine really fast on the highway.

The car came with 185/65-15's. This gives a tire diameter of 24.47". The 270/45-15 tires are 24.57" in diameter. What am I missing?

You are missing the part where Clay doesn't know that the 2nd number is a ratio, not an absolute.
