www.protegegarage.com is taking pre orders for a lightened fly wheel for the 2.3l. made by fidanza. free shipping and is 4 bills. just thought i would let you all know. the only other fly wheel for our cars that i know of is sr motorsports and thats 5 bills. though fidanza isn't saying what theirs is going to weigh. i checked the site and all they have are the mazda6 ones with a tbd for weight entry. anywho i know i can't wait to unleash that engine in my 2.3 and a light weight fly wheel is a great way to increase acc times!!!
