If you going to use them on the track I would go with the Dunlop Direzza Sport Z1 Star Spe, since you have a 2012 I can’t say if your need to roll the fenders or not.
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.
