Hectic start for you Matt but good results never the less and NOW you have a strategy
I honestly believe that whilst these tyres are brilliant they have a much rounder profile (virtually no-one got to their edges on the rears). Average 'chicken strip was between 0.25" and 0.5".
This makes them a bit slower to turn in and have a tendency to run wide, so suspension set ups from the Pirelli's won't cut it.
I definitely need more ride height but my shock doesn't have that facility
May be able to dial it out a bit with Compression/Rebound dampening adjustments... Unless someone has a cheap'ish shock with ride height facility going???
