Will I reach 10,s??

.....The spool will ET SLOWER than a sure grip with the same gears as the spool takes more power to turn than a sure grip...

I don’t see how running a spool would slow the car down. I changed from a sure grip to a spool years ago. I don’t know the exact weight savings, but I know that my spool is VERY light (just a couple pounds) were as the sure grip unit that I pulled out was quite heavy (30+ pounds)….The weight savings alone are huge, not to mention SOLID, consistent traction on every pass.

Could you please elaborate on why a spool would slow your car?
