My wheel is smaller, but it wasn't significantly harder to turn the wheel. One thing that did make a huge difference was suspension, new tires, and alignment. The wheel is very easy to turn, and I have almost no wondersteer.

 

I Cut the spokes off of my old stock wheel then Centered up the Momo to the Mazda wheel, Indexted the bolts Drilled & Tapped, then bolted yhe momo to the mazda. It works great & I still have all the stock horn wire and turn signal Cancelors

 

The momo hubs come with wiring for the horn anyways.
