new cat on the block
 

Hi guys!
I´m an spanish driver out of the hobby for the last 3 years. I´m back even more motivated and raced a couple of races.
I´m getting a CAT S1 in order to race the spanish nationals this year and since I think right know I´ll be the only Schumi driver, I´ll need your help for sure often.
I checked out the whole info and I already doubt about a correct set up for non high bite tracks. Unless the EFRA at Bilbao which will have astro turf, the rest of the championship is on medium bite surfaces.
Should I use softer at the front? Which springs for an starting point?

Thanks a lot.
