kyosho arms. when dremeling them make them the right size to where there is no shims needed in the front or rear

if you cut the bottom tab off the diff case and put a set screw in the top one you can lower the angle of the rear drive shaft. doing so will help with power transfer and life of the cvd.when doing this you will have to cut the battery box as well as some of the tray and grind down the rear motor mount a bit to help clear the drive shaft

i have cut the tray just passed the throttle servo. i left the mounting screw there and cut just passed it

i have relocated a hump pack to the front. using the remaining of the left over tray and using the rear tank riser to secure the battery to the mud gaurd. you can also put a stick pack there and just zip tie it to the mud gaurd. hump pack offers a little more weight up front. as well you can see the servo standing up. use tekno universal servo mounts. work great.will require to drill 3 new holes in the chassis and countersink them. (not for rookies)

personaly i felt a big difference with lowering the rear diff angle and putting a stick pack up front.

standing the servo up is only necessary if you want to run a hump style pack lipo

but i would suggest doing the diff mod.. more acceleration..smoother drivetrain.. and smoother accerlation

Do you have any pics of the diff mod? Also I'm assuming you cut the case to drop it down. Did you put anything above the key too keep it from shifting back up? Thanks.

There is a much easier way to improve the front and rear CVD: Get a set of Mugen 2.5mm pins, cut them to length and slot them and use them instead of the stock TD CVD pins. The stock pins are about 2.4mm and cause slop in the CVD, which returns in wear on the holes in the CVD. With the thicker pins, the slop is gone without any binding and the wear is significantly reduced.

What I do is predrill a hole in the top one and insert a small set screw. And just tighten or loosen to reach desired size.

Ill try and get pics when I do my diffs this week.

Good info guys! I've already done the battery forward mod and will do some testing when racing starts around here in April.

As for a more thread specific post. My DNX408 will be undergoing an off season rebuild soon.
