I would look at a Toyo Proxes RA1 225/50/15, my recommendation would be to have then shaved, full tread they are a bit squirmy. And being your probably running stock camber they won’t wear all that even, so your better saving them and rotating them frequently.
My rides a 2002 SVT track car, & Boosted 2007 ST with the SAP.
The helmet has a special meaning for many drivers. How important is it to you? - It protects my head.
Do you have any special rituals when the helmet is concerned like many have? - I wipe it so that I can see better.
