I prefer the pedrini wheels. I like the look a little better than the mahles.
Pedrini:
This is personally, my favorite 914 stock wheel, the Pedrini. The Pedrini was a 4-bolt alloy wheel offered from 70-72, and at first glance is very similar to the 4-bolt Mahle. There are two different types of Pedrini's out there. Early (and most common) Pedrini's will not fit on later (hubcentric) cars.
Mahle:
This is a 4- bolt Mahle wheel. Factory option from 73-76. In 1974, these were stock on all Limited Edition cars and were painted to match the trim (yellow, orange or green). It sounds ugly, but looks cool.
