Just done a couple of days testing for the IIC on the sweep tyres. Main focus was to improve corner entry as this is what most have said to me they have been missing at EWS this winter.
Track was a lot smaller than EWS but the same style 'low' traction ets rug. I actually found the sweep tyre very good. very consistent over its life span and around .3 slower than sorex over a single small lap but a good balanced tyre.
Ending setup gave good balance and front end traction. and was very good in fast sweeping corners.
Note rear toe link and diff height, also played with bell crank vs LS1, but prefer LS1 on this tyre.
