hi everyone!
I am trying to get my curb weigth down a bit more, but I am at the bottom now to keep the car as daily street driven (1190kg ~ 2620lb with full gas tank and w/o driver).
So I thought to reduce some rotating mass from the engine. I have oem clutch and JUN fly, but the Exedy twin carbon weights in total just 18lbs but produce noise from the flaoting discs when the car is not rolling (have this clutch on my race car and I love it).
Well, now I found that the ATS single carbon clutch only weights 18.5lbs compared to 35.5lbs stock. Thats about just half the weight for the ATS clutchkit. Anyone who has experience with this clutch?
Reducing weight via an aluminium crank pulley is not good for long terms (vibrating)
Other parts like campulleys and pulley from the alternator is also a way to go. To bad those cam sprokets are like 1000usd from comptech. I guess the diff is about 0,5kg per pulley? So this would be also 4 kg ~ 8lb in rotating mass. Worth it? For myself I have to say Yes.
