This is what both my rears looked like after last weekend auto-x. It wasn't
even hot outside. Is this an indicator of anything particular I'm doing wrong? About the only abnormal thing on the course was a long 180 that was not quite a hairpin but I had the gas pedal to the floor for the whole last half of it. Basically with a 2.3 and limited slip and my setup, no possible way to spin with foot on the floor. |

Yeah, I actually found that the 'adhesive remover' blade for the vibrating saw tool
thing gets the excess rubber off pretty easily. So, my tires aren't blue or ridiculously worn after 5 events (8-9 runs avg). However, at the last event we did 6 in the morning and 6 again in the afternoon. By the 5th and 6th runs the car felt really sloppy and even though I was driving a better line it was slower. Not 'overheating' but out of the good grip temp range of the 'A' compound. So, IMO the A7 is inferior to the A6 where I never noticed this. Either I should go to the R7 or find something else maybe. Anybody looking for a good deal on used 205-45-16? |
