Just 25 hours? I was going to get a group of techs to work on it.

It was only a minor concern since it took me a couple of TD's last year to sort out a suspension problem.

Too late for that. jk.

What you and @Otto Man said make sense, just wanted some reassurance. I started writing my settings down like @ZedExMuse had suggested and it's been a big help with understanding the effects adjustments have on the bike, and now I get to see what effect the tire ratio has.

The one thing I kinda do like is the different personalities of the community...there's a lot of shit that is of zero interest to me, but some of that stuff, other people go into the weeds over...so it's a good chance for me to learn a thing or two. There are some things I'll never waste my time on trying to start from square 1. Suspension/bike set up is one of them. Thermosman has seen more bikes, more of what works and what doesn't, than I ever will. He's forgotten more than I'll ever learn. So I ride what he gives me, make minor changes if need be, and ride it.

I have also seen people obsess over things they should not be wasting any time on. I will never forget the "gearing guy" at Barber. He was adamant that his gearing was so far off and that's why he wasn't riding the pace he wanted to (he was like turning 1:55's on a CBR600). I would go out and follow him for a few corners and see he was missing every single apex, running a gear too tall, couldn't set up a pass to save his life...but got damn, I tell you what...that one or two teeth off on the rear sprocket was the reason he couldn't keep up with his buddy.

It is always those that use their brakes the least that want to upgrade them the most.

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?

Just for some perspective................. , even if shipping would add $40 to the deal.....

This is what I sell these tires to my customers for (I typically do not ship or sell just tires without install... fyi)

Dunlop Q3+ (pricing limited to stock on hand)
120/60-17.............. 110
120/70-17.............. 110
160/60-17.............. 135
180/55-17.............. 139
190/55-17.............. 160

Dunlop Q4 (pricing limited to stock on hand)
120/70-17................. 110
180/55-17................. 130
180/60-17................. 135

woohoo we are having fun now
Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

Gotta be slicks. DOT have to go one way. You know the Michelin power RS lasts a lot longer than the Q4. Or Iíll sell you take off slicks cheap

At first I agreed but not anymore. I have a mild wobble at the front. Feels twitchy.

Clearly the only reason to run 30 seconds off the lap record.

So bike front end feels twitchy after you raised the rear by moving to a 180/60? This would fall in line with what you could expect from increasing shock length I would imagine. If you have any rear adjustment from an aftermarket shock or from adding a spacer you could try reducing that height to where it was before the increased tire diameter.

Relax. I'm only 20 seconds off the lap record.

Anyone hear much about these yet?
Found one post from Nate Kern on FB, seems he tested them at Roebling for a track day...had good things to say but didn't explain much more about them other than they had good wear and thought they were better than the SP's.

Would like to find some actual technical info but there isn't even anything on the Pirelli website lol
Seems the line-up would now go Pirelli Slicks>Super Corsa TD> SuperCorsa SP's

Here's some more information for anyone interested.

I asked Pirelli where the tires fall in their range, their response was that they are a DOT tire that falls between the SC's and the SP's
Pretty good deal for a set at $329, cheaper than the Q4's from Dunlop. Will be interested to see some comparisons and reviews once they're out in the world longer.

Wait - I can get a set of Q4's from you for $245? Can you ship those?
