So fit new ones..........
A rally (65 miles) uses just over half a set of fronts, so its not a difficult decision. DS3000 rock also, I use more 3000's but I did a very very fast rally in the cordy on 2500's and was very impressed with the bite and progression. 3000's are a lot harder to modulate on the grip limit
IMHO
We tend to rally on a mixture including poor surfaces, wet, cold, broken surfaces, gravel etc
3000's on the GTIR though , as they are paid for..
