I've just [within the last 2 weeks] replaced my fronts with Dunlop SP01 sports. First impressions were a firmer ride at the front but with increased road noise. Can't tell what the wear is yet but they are scrubbing in well across the tread and on the outer edge. No wet weather driving yet so can't tell you anything about that.
However, I think I have noticed a difference in front end grip. As previously stated, the fron end on the 9000 can understeer badly, and had a prime example this morning. Hit a 90 degree righthander at around 30, in the dry and one that I've been around many times before. Started to accelerate and suddenly found the car going straight ahead instead of turning
. Backed off the throttle a touch, straightened and returned and the tyres bit and she turned. Nearly kerbed the wheels [standard 15 inch cross-wires] but didn't touch.
I know I'm a forceful driver, not one for hanging around if you know what I mean but not had this degree of washout before. I'll temper my style until I find the balance between speed and grip with these SP01s.
Just thought I'd share my experience from this morning!
