So this is effectively a 18x9 +41 offset, should fit well for a stock suspension.
However...
I'm not at all a fan of spacers over 3-5mm except for the bolt-on spacers which are usually much thicker than 10mm. That's means your lug nuts will grab onto the studs 10mm further out (how many threads will they even grab?).
If you have the ability to do a test-fitting, I would try it first and perhaps try a smaller spacer (5mm) and see if you clear. I wouldn't personally do a 10mm spacer on mine, but ymmv. 51 offset on its own will definitely not clear the strut though.
Edit: If you are only using these for autocross and track, I would strongly recommend not using any spacers and finding a proper sized wheel. For those applications, your best choices are a 17x9 wheel (lighter) and you'll have a better choice of sticky tires to choose from. Ideal offset would be around +40 in this size.
