First, the KR451/448 isn't the compound codes, That's the model number of the slicks, The compound codes are a 4 digit number on the same side of the tire as the balance dot
Homestead can go a few ways on compounds depending on the temp, and the wear you are looking for. Are you looking for the fastest tire you can get, or a tire that will last a long time. I know, I know, you want both.
Our customers that come from Pirelli. we normally suggest starting with 0129 fronts and 0129/0097 rears. These are fast compounds, not the endurance compounds, but they also have a more similar feel to the Pirelli tires.
