    So I sold my project car and have some extra cash to throw at my Tacoma.
    I am looking at getting the clutch masters internal hydraulic throw-out bearing setup with a stage III clutch from URD and the clutch accumulator delete mod.
    My big question is my flywheel. I am looking at the URD lightened flywheel vs their heavy flywheel.
    I like the idea of being able to rev it up quicker and get the performance out of the lightened flywheel.
    I don't off-road a lot but I do drive the freeways and get stuck in traffic. So the heavy flywheel sounds like it would help in these situations. I would like to set it up for some off-roading in the future and the heavy flywheel sounds like it will make that better.
    Anyone have any experience with a heavier than stock flywheel? Do they feel like it lags when you try to accelerate? I would like to be able to pass on the freeway without it taking forever to get the RPMs up.

    A heavy flywheel will help torque like stop & go traffic and crawling around offroad without hurting rpm's, won't rev as fast as a porshe but won't take long to get there.

    A lighter flywheel will rev fast but need throttle to start moving and crawl around.

    Look at it this way,
    light is high reving easy, ie: horsepower
    heavy is longevity not as fast good for lower rpm's ie: torque.

    If you want a race truck go light,
    if you want a truck that works stay stock or a little heavyer.

    Thanks sparkystaco.
    I am really leaning towards the heavy flywheel.

    I am running their lightweight steel flywheel on my v6 and I really like it. Sure it takes a little more manipulation to get going, but you get used to it pretty quick.

    If you are planning on off-roading in the future though I would stick with stock or go with the heavy one just to make things a little easier

    URD stage 3 has a heavy pedal feel, so take that into account if you have to drive in traffic. It's a bear to push in compared to the stock one

    Do you really want a stage 3 clutch? Even with internal throw out its more work, I would never do a stage 3 unless you had significant power adders.

    So basically a Stage 2 clutch would be better? Or is that even overkill for a stock engine?

    Stage 3 is overkill for most supercharged trucks, mine included. It's rated to 500 *wheel* torque and as others have said it is very heavy and has a very immediate bite point. Not very user friendly for stop/go traffic if you ask me. I'm looking to swap mine out for a less aggressive clutch for more drivability, the previous owner put this one on my truck.

    Stage 2 is still rated for 440 wheel torque which again is significantly more than stock or supercharged trucks get. The TRD/magnusun supercharger is rated at 335lb-ft of torque at the crank, not even at the wheels.
