Valid points, although the rear sliding is what put me where I am now lol.

Like I said before the issue is more me than lack of traction in the tires. I do like knowing I have the same rubber up front and out back. It's just one less variable to have. Confidence is key.
confidence is the critical thing for me. When I started back racing a few years ago I started on Supercorsa SC. I then tried a couple of other brands, one seemed to grip but I couldnt get it look like it was working properly, another brand started good then it just started tearing apart. I came back to supercorsa.

I run the same pressure all year at all 3 tracks i race at, and use warmers. The warmers here may not be technically necessary but I know with these tyres off warmers that I dont have to worry about tyres and can just concentrate of everything else.

Agreed, if you like feedback from your tires Pirelli SC'S are for you, if you like a tire you have to keep hot as hell running mad pace that are mute as a mime, then US Dunlop are the choice. Bridgestone don't last here in the SE USA, and Michelins are a good go between. I personally love how Pirelli tires talk. I wouldn't ride anything else.

Next time you have 2 different brand fronts off the rim, angle the tire off center and push down and you notice that you can see the contact patch from the inside. Now do this with a Pirelli SC....you'll notice how much easier it flexes with less force, and the patch is significantly larger. Now move the tire around and watch how easily the patch moves. That's the difference between Pirelli and the competition.

**Disclaimer, this is race rubber used on a race track at race pace.

Not that it's a comparison, I've run pilot power 3's, Q3s and the SP's on the track thus far. I HATED the Q3. Felt like everything was a guess. Never received any feedback from them and had very little confidence on them. I took them off after just a couple track days. I liked the PP3 but that was on the ninja 650r but I would guess the balance of feel and grip would follow onto the GSXR. I'm looking forward to trying a DOT race tire. VIR in September will probably be the first chance to test them out.

I dont post what tyre brand I didnt like as it does not mean they not good, just that I prefer SC. riding style bike set up etc etc.

I run 110 front and 150 rear so dont have the full range of models in other brands to choose from.

Main reason for guys not running SC here is cost, they are much more expensive than other brands.

I am running at lap record pace on all three tracks, I have given up on cost, tyres are getting eaten, every second quicker on these small tracks dramatically increases wear. I just ordered 8 tyres, just dont look at the bank statements!!!!!!!!!!!!!!!!!!!!!!

Just back to my moto, tyres are cheaper than time off work.

Nothing wrong with providing an opinion about specific brands/models. If you just simply say everything else doesn't work it isn't really any help to you or anyone else.

I haven't done a thorough study, but Pirelli seems to have some of the better prices in my area for DOT and slick race tires.

How's the new SC rear treating you? Curious as well, are you riding these tires on the track only? What kinda of mileage are you getting out of the front tire?

The performance of the OEM SP V1 tires on my 675R dropped considerably after about 1,500 miles.

Haven't run the SC's yet due to my shoulder injury. Mounted and ready to go. Running track only. I have 4 or 5 track days on the front and it probably has a couple left in it if I decide to keep it on. I haven't noticed any more drop than expected.

Ironically I had my stock suspension set up .. did sag and free sag and my mechanic also insisted I do 33/30 hot.
This is what I got.

I sent this info to Dave moss and he said cold tear.. seems right because prior to this track day I had lower psi.. I've also seen videos that claim leading and trailing edge wear like that indicates a suspension adj needed but I can't remember what.. I think it was rebound

Digging up an old thread, but I destroyed my last 2 tires in a day each trying to chase pressures.

I've come to a conclusion (maybe incorrectly) that this is what Moss calls a geometry tear, basically a cold tear but from incorrect geometry/suspension set up instead of primarily a pressure issue.

With all the shimming the rear we do to get the bike to finish a turn, things can go too far where the rear suspension simply is not getting the load transfer it needs. Too slow compression (excessive comp dampening) or too little sag or too much preload can contribute to the problem.
