Some Questions About Stock Vs. Aftermarket Flywheels for the FiST

[chargers3498]

So I can't find a whole lot of supporting information about the stock flywheel in the 2015 FiST and I want to know what it weighs vs. what some of the aftermarket ones weigh. Has anyone on here upgraded their flywheel and if so how hard was the install and how much of a difference did it make? I would like to but I don't want to have to mess with my clutch as well.

Look up T shirt driving on YouTube for weight. I think someone's done one but never reported results.

From http://www.motoiq.com/MagazineArtic...etrain-with-Mountune-USA-and-SPEC-Clutch.aspx

"The stock flywheel was pretty heavy as it included a damper in it, presumably to reduce NVH. It weighed a substantial 25 lbs. The spec clutch weighed only 11 lbs, a 14 lb saving in rotating weight! "

No follow up article on how it drives after install yet.

My worry is that removing the dampening of the dual mass puts extra stress on the gear box. i would love to lose all the weight but i know of 2 guys over this side of the pond that went single mass and upprated clutch and it broke the gearboxes. one of the guys persevered till he was on his third and gave up in the end and went back to standard. both cars were big turbos running around 300whp mark.

Any nutters over there put a Quaife sequential box in one of these yet (cars still driven on the street, NOT trailered race cars)??

dont think so, quaife dont make gear sets for us yet. the only option so for is cryogenic treating your standard gearing with some shot peening or buy a Sadev sequential box thats available for the fez. thats if you have about 15k lying around

Is the Sadev box a direct bolt-on, or is there a lot of fabrication involved to get one on these cars?

sorry to the op for getting off topic.
yes one of the boxes is made for the 1.6 turbo fiesta but not much room for more torque. the next one up looks better but not sure on fitment for that one. they have options on them all for ratios, flappy paddle gear change, dash gear display and more.
