I'm sure this has been posted before somewhere along the way. I bought a lightweight steel flywheel from tweakit. I was wondering whether or not i need a counterwieght from an automatic trans? I've heard that you only need one if the flywheel is really light. Oh yea, mine is a 5 speed.

 

you need the counterwieght to bolt the flywheel to the engine

 

Youneed a counterweight that matches your rotors.

 

So, if i have an 85 manual, i need an 85 auto counterwieght?

 

85 12a? or 85 13b? they are different couterwieghts

 

OK, I get it now
