    Lighted flywheel typical price?

    What is the average price shops charge to lighten a stock "i" flywheel down to 14 lbs?

          I was shopping around to get my single mass eta resurfaced, lightened, and balanced; and I ended up paying $110. One shop wouldn't do it, and another wanted $450 to do it. You have to be careful and find a good shop, or you could pay a hefty price. Pun intended?

                $100 is about the going rate but even at $160 that's a much better price than buying an aftermarket one!

                  how safe is the lightening? it doesnt weaken the flywheel too much?

                  a high clamp loading pressure plate isnt going to over stress it? and it will stand up to horse power and torque sweet as?

                    I knew it was sorta high but the machine shop quoted me 300 at first lol.

                    I ran with it bc the shop is very reputable and badass.

                    Plus I got the flywheel for 20 dollars shipped.

                      It's fine. For reference:

                      M30s. Stock have a 26lb FW.

                      S35s stock have the same FW, but it weighs 15lbs.

                      S35 is much > M30.

                      You'll have no problems.
