Hi! I just got a RB lighten alum flywheel from a forum member. He states that the flywheel came off a s4. I measure the counter weight according to mazdatrix's website. http://www.mazdatrix.com/faq/Rcounterweights.htm The counter weight has the measurement of the s4 unit but looks like a s5 unit. Should i trust the way it looks for believe in the measurement? note: I am pretty sure that i measured it correctly since the reading difference is so big between the 2. Any help would be great

no.. do you know the weight by chance? is a s4 non-turbo. So far i am unable to find the spec weight for the counter weight unit. thanks!

 

S4's are supposed to be 4 lbs
S5+ should be 4.2
