Hello fellas , in your opinion and experice, when does small brake kit and 15" slicks become an advantage over 17" setup? Most popular being 17" with Hoosier and 15" with MT slick. Please share your experiences

No one has any conclusive comparisons between the 2?

Thanks for your reply . Is there a  disadvantage of being sub 1400whp and using the 15" setup

Depends on combined tire and wheel weight.  All being equal?  No.  15" drag slick with same outer diameter will generally outperform a 17" drag slick.  But you HAVE TO TEST IT.  Each car is different and it depends.  But it's next to impossible to find a 15" and 17" setup that will have the same weight and performance.

15” also requires a much more aggressive burnout than the 17”.

Would it not be the opposite? i.e. more tire to absorb the drivetrain shock of launching?

I run the 15 inch slick. The T1 package with the smaller brakes. It is an awesome set up. I consistently pull 1.2-1.3 60 foot times. I also do not do any burnout at all.

yes to certain degree,there’s more tire sidewall to absorb the shock,but coming of launch control and dead hooking somthing is gonna give over time.

Why no burnout at all?

I have the Syvecs controller. It is a bit of a process to put it in rwd and back to awd after the burnout. I did a few runs with doing a burnout prior and then did runs not doing a burnout and the car ran the same numbers. So I figured between the wear on the car and the "sequence"/time needed to do the burnout really wasn't any benefit to me.

Scuba Steve is another local. He runs a 17 inch slick and I believe he only does burnouts occasionally. I will have to text him and see if I'm remembering correctly and what difference in times, if any, he sees.

Just texted Steve and he also does not do a burnout. Both of our personal bests have been with no burnouts.
