I put on a pair of Q4's last year and absolutely loved them. They look not too different from the Q3+ but they are much softer and felt like they'd grip forever . But I tore the rear up in two sessions at Thunderhill - that track has a lot of high speed left handers linked together and it was too much for the soft rubber. I spent some time dialing in the rear which seemed to help some but I think I don't need that kind of wear rate. I went for the 180/60 rear and that seemed to help turn-in from the steeper geometry it creates.
I think this year I'm going to match up a Q4 front with a Q3+ rear - the sticky front tire gave me a ton of confidence, but the wear of the Q4 rear would mean way too much $$.
I just checked on pricing at STG for the different combinations (before rebate):
1) Q3+ front and rear (120/70 + 180/55) $282
2) Q4 front, Q3+ rear (120/70 + 180/55) $153+158 = $311
3) Q4 front and rear (120/70 + 180/60) $354
I think with either option 1 or 2 I could go 6-8 trackdays on a set and between those I think I'm OK with spending the extra $29. With Option 3 I'm probably changing the rear every 2-3 days so that would probably run me an extra $300-500 for the season.
Is it OK to flip the rear tire with a DOT type? They always have rotational marks on them. The left side of the Q4 rear really gets eaten up at Thunderhill and it would be great if I could reverse it and get another day or two out of it. Or can you only do that with slicks?
