what would improve rolling and dig acceleration the most. a ACT clutch/prolite flywheel or mrev2/spacer/popcharger?

 

I think the mods would help more, but you will replace your OEM clutch setup long before the ACT setup if you like to launch from a dig and your n/a.

The ACT setup and new tranny has made my Z feel like a different animal! I never hit a gear anymore and acceleration is brutal. The best part, no clutch slip smell. I guess the holding power of the clutch(500ft lbs) keeps things in check My 295s @ -1' help too I guess... LOL!

i think they both will have an equal effect. The bolton's are going to give you a harder accleration (pull harder) while the clutch/flywheel replacement will actually make your RPM's whined faster on the tach. Which is better, a clutch/flywheel are 3 breathing mods? HP wise, i would say the breathings mods. Toss up though, either way would be a nice improvement.

^^ only on n/a

 

New LSD and 3.9 gearing. And N2O

 

so if the car runs like 13.85-13.9 stock, what would it run after lighter wheels & tires (rears will be 275s, losing about 30 pounds of rotating mass) and a 13.5 pound flywheel? I know theres no way to know for sure ever really, too many variables, but you think combined itd take off 2-3 tenths between stock & what i'll be putting on?

 

Light and small diameter wheels make a noticeable difference.
