Been working hard on the front suspension design which is testing my nerves – just like 12 years ago. Since I’m using Mazda Miata front uprights, I wondered what kind of numbers Mazda used. The internet revealed the stock suspension points, and even if they aren’t exact, the Miata’s setup is very interesting! What I find fascinating is how Mazda doesn’t follow the commonly held notion about keeping the roll-center stationary, not even close. But if it’s examined using force application points, figuring that the outboard tire carries most of the load, then it works. Of course, the reality is that it (the car) works just fine, as Miata owners will attest. So it’s very interesting how Mazda’s setup violates the so-called stationary roll-center rule… very interesting indeed. So, good, this means I┬ápress on with my suspension design and hopefully have some good numbers this week. Once the front suspension is done I can start working my way aft.
