3 Questions
1. Engine shaft - When you pull on the pinion Gears, how much movement should there be? I have shimmed mine and it moves about .1 to .2 MM.
2. Front Diff - Where do you get the Spool or Gear diffs at? I ask because I have a one-way and don't like the fact that breaking is near impossible without spinning out.
3. Springs - I have noticed some are running red springs on the rear from a Prospec. What is the rating on them compared to the black standard springs?

i shim mine to about .5mm. It is possible to break properly if you setup your car properly. One the guys using a hudy tweak board to tweak his car and the breaking of the car is awesome with front one way.

I tried to shim it at .5mm and the gears get what appears to be too much up and down movement(slop). When I add 1 more thin shim it eliminates the slop, but does not leave much in/out movement. My concern is if there is not enough in/out movement can it harm anything?

Well. Just found out something else today about the D3R. The flywheel now sticks out like 1-2mm underneath the chassis. I guess the motor itself sits lower.
So now im kinda stuck on what I should do. Seems like the R40 isnt very friendly to motor fitment. My nova fit great though for everything , too bad the darn thing flames out and is a 5 port anyway.

2. You can order a complete 4 gear diff and spool (just an aluminum plug) at tower or pick them up at your local hobby shop.
3. I think that the red proceed springs are a just little softer then the stock black. They are shorter so you can lower you car more.

sure you didn't use a larger flywheel or a lower height engine mounts ? the mouting dimensions on a STS should be the same as a NR.

Ill check mine on thrusday to see if mine is the same. If it is I didn't notice any difference with it.

Try it, it will make you faster.

Sweet finally found a lightweight flywheel for our cars. Also got a titanium brake disc and a new handle.
Stupid stuff but it was cheap. Except for the flywheel. But im hoping this helps the engine braking torque.
As lightweight flywheels always make the engine rev up and deaccelerate faster. Only problem is this could also make breaking traction easier. Im hoping it helps pep the car up some.

I know... it seems to be a very important part of te drivetrain on the car. I have looked on 3Racing's website and it says they are out of stock..... I am just wondering if the Mugen flywheel would fit the R40.... looks liek the same flywheel...... and you can use mugen clutch parts with the R40 clutch, might be a possiblity......
