Which MT tire for 800hp SRA cobra w/ Poll

[blknredsnake]

I have a 2004 Cobra built everything, 2.8kb with monster inlet make 804/680, i have a SRA and i currently have 325/50/15 MT ET streets. I am using the car 90% on the street 10% track and i need a little more grip, i was deciding between MT ET street R's, the street/ strip and the MT ET Pros. Idk if anyone has used the new MT tires yet but i appreciate the input.

The ET Street Radial Pro is not a street legal tire. Not sure if that is the Pro you were referring to or not. I believe the R is mottled after the Pro and that gets my vote considering how well the Pro's perform.
