Cool Upgrading Compound

I have done a few searches and read some good stuff on here, CLSB and WERA/CCS forums. A lot of in information was good but still jumped around my direct question.
Currently on my dedicated track bike I am running Dun Q's. I love the tire and they have treated me good and worn well from my beginning track day life until now (1 year later). However I am looking to go to the next step on tires as my current set are towards the end of their life. I want to switch to Pirellis, set in stone. I was originally going to go with DC III's as that is a decently close match to the Qualifiers.

However, since they will be mounted on my track bike I was thinking of going with the Diablo Super Corsas Medium compound. I want the tires to get me though 3-5 track days for my first set. I wouldn't say I necessarily push my bike hard to the point where my bike would be eating tires in 1-2 track days. I am to the point where I would like to get onto a tire that I could chew up in 1-2 days when my skill level is at that point.

My questions:

Is it good to start on a DSC even though my skill level is not at say the level a person who NEEDS a Super Corsa?

My thinking is that I will get used to this tire, so that when my skill does come up I can make full use of the Super Corsa.

For the compound I see a lot of 2/3 (F/R), is that a good choice to start off with? Will a 1/2 work just as well for my current level?

What about a 3/3?


I appreciate the help as I know I will get a lot of good information and conflicting opinions (which is good, allows me to see all sides of the discussion).

Cheers

Diablo Corsa III's will get you will into A group pace, last longer, and be more versatile (better in the rain or cold, less need for tire warmers). Added grip of Diablo Super Corsa Pro's can't hurt but I figure why waste the money?

I always wanted to kick myself for wasting money on race tires when I was in B and I group... coincidentally enough, I now run shittier tires (other peoples take-offs) at a faster pace than I use to run with new race tires.

If you do go with the Super Corsa Pro's though, I like the SC2/SC2 combination, seems to work pretty well at most tracks.

Also, post up your lap times at some tracks, it might help w/ deciding which tires to use

For the New (last year) Diablo supercorsa greens (med) I usually figured one race weekend (2 GT races, 4 sprints, 4 practices) and then they were relegated to a track day or two until they were finished off. I don't know how long the pro's will last as I haven't used them much, but I have a feeling that's what the R1 will come with at Topeka.

Diablo Superbike medium compound slicks will last longer, but will cost you over $400.

SO Aaron, you may not like my response. Here it is.

DC IIIs are the way to go. And btw, 2/2 is the best solution unless you are going to Putnam. (Putnam would be 2 front, 3 rear)

Race tires are for racing, or going at race pace. As such, your pace is not at the level yet that would require Race DOTs or Race Slicks. DCIIIs can go WELL into the A-Pace for NESBA riders. (Note: A-Pace is race pace or better)

SO.. where is this coming from? This is coming from a guy who bought the best race tires and suspension from the beginning. You know what I found? I found that I wasn't good enough to take advantage of the extra grip that Race tires bring. I found that I couldn't put enough heat into Race tires in order to run them at the temps that they were designed for.

DCIIIs are an EXCELLENT tire, and they can handle a far better range of temps than a race tire can. They operate better at lower temps than a race tire does, and they have more all weather capability than a race tire does. Finally, the last LONGER than a race tire does.

IF.. IF you run on hot days, with tire warmers and IF you are running race tires at temp, then the race tires can hold a better line a a much higher pace. But without the pace, you'd never know that. As a matter of fact, without the pace, the DCIIIs will outperform race tires in a broader range of conditions.

So, to sum it up. Get race tires when you are approaching race pace. FWIW - I have run Pilot Powers, Bridgestones, Qualifiers and DCIIIs. ALL of them perform great at B and I pace. They all have differing characteristics in feel and performance, but they can all do the job. For the kind of riding I do, for the feel I like, the DCIIIs are the best non-race tire for me.

I think that was more than your .02 worth, you owe me a beer from all the tire money I just saved you.

Wink to keep up with the dollar being inflated I think your .02 should be stated as .25

Thanks greatly appreciated!

Umm... Pirelli.

Although they seem to be slower on my bike than they are on everyone elses.
