A7 vs soft Slicks

[flyhalf]

I was doing some calculations and I'm so far to max out TT2 (because my weight) that i can mount slicks and also loose 100lbs and still be in tt2.
So here's my question.
From ONLY A PERF POINT OF VIEW.
A7 vs S8M or S7M (Again the s7 or s8 which are the softer compounds). What is worth in laptime?
Lets take 2 min lap. how much can a slick shave?

I believe @ArizonaBOSS recently went to a Michelin slick and may have some info for you..

For me the 30/68-18 tire is a perfect size. I like the width and height, wish Hoosier had a 680mm equivalent. the 315/30-18 is more like a 650mm.

Too tall for me. I gotta have a 25.5" or 26" tall tire
I'll be running my Hoosiers against cars with Michelins at nationals.
Wish me luck.

What about a Hoosier Slick , not sure about the sizing, but that might be another possibility.

thats gearing for ya!! Was just thinking, my Dunlop 300/680-18 got almost the exact time as a R7 in 315/30-18. And the same Dunlops (in other sizes) get the same times as Michelins on the GT4 CS cars.... So if you take the long road... A set of A7 could be faster S7M??? Stretching a little ....

About a second, depending on your tire guy,maybe more..

I've been through this with him he runs an oddball size.
