they are almost direct fit. you just need to find 10x18mm bearings which is rather hard.

once you get the rear diff, you will see how you have to grind down the edges slightly because it is too wide (by 1mm or so) and I suggest you take the most length off the right side and then the rest from the left to help center the belt.

front diff - is a direct fit, just need some shims (10x12) to make it wider or else it would be too loose.. front diff will also require you to run the rear cvds at the front. (lucky i had some spare)... otherwise if you run a spool, you can just do the rear diff...

rear diff - needed some dremeling as its too wide. i dremeled the bulkheads as you rarly change the bulkheads, and i can change rear diffs easier, rather than modifying 2-3 diffs to fit the bulkheads.

the rear diff is also 1tooth/1mm smaller, so you need to make new holes to make the belt tighter.

run capricorn diffs, and you will save 20-30g per diff (40-60g rotational weight). xray diffs will save you about 10-15g per diff.

cant wait to test this out.. titanium main/mid shaft, titanium 2sp holder, lightweight brake holder, capricorn clutch, capricorn diffs... thats going to be one light drive-chain.. i havent ran my car since iv changed the entire drive-chain..

my car looks like a nt1 now :S, only thing giving it away are the shocks.. which are soon going to prob be nt1 ones aswell.

Having built both, that would be a backward step. Kyosho shocks are renowned as the best in the business...

Maybe you should have purchased a NT-1 or Capricorn to start with.

iv had my RRR for a while and didnt want to change... it already had all the upgrades on it.

i received the capricorn top-plate and etc for free from capricorn.

only thing i did was 'upgrade' the diffs because i wanted to make the car better..

and i guess because its more unique no one has the same car.

So capricorn diffs are a direct swap for the kyosho evo 2?

Any part numbers please? and a good place to buy them

Thanks

no, capricorn diffs are same as xray, just lighter, and it has plastic carbon gears and lighter cups.

to fit xray/capricorn diff, you will require to do abit of dremeling and shimming...

also you will need 10x18 bearings - these are very hard to find, unless you know someone who has them, these bearings are going to cost you atleast $10-15 each. you will need 4 if covering front and rear.

if you convert the front, you will also need to run the rear cvds as the standard front will be too short...

i spent hours working out different ways to fit the diffs

lucky i saved on abit of parts. if you were to do a full conversion it would cost

bearings - ~$10ea x4 = $40
diffs - xray ~ $49 x2 = $98 (according to amain), capricorn would prob cost more.
rear cvd - $38 (according to amain)
shims etc - $10
$186+ - not including postage and whatever extra it cost for capricorn diff.

if you run spool and do the rear diff only, it will cost you half of that minus the rear cvd's ($38)

vxb.com sells 10x18x4 bearings that you need at $5/each and you have to buy 10, you might want to pick up 10x12 shims as well to center the diff.

you can buy capricorn from team epic (trinity) in america at a cost of about $45 per diff complete.

here are some weights for the rear diffs

41g RRR diff, titanium shafts and drilled drive cups
35g Xray EC diff, drilled drive cups, not sure on the shafts, metal gears
25g Capricorn stock, drilled drive cups, plastic gears and aluminum shafts.

one note, I usually run 30k in my RRR diff. To get that same feeling I had to use 60k in the capricorn diff. The xray mold looks extremely similar to the capricorn mold, even the small molding dots are in the same place.

Unfortunately it's been raining non stop here in Houston so I have not been able to test anything other than it spins so the 1mm / 1 tooth size difference is unknown. the wheels rotates fewer rotations if you just spin the rear wheels and wait for the drivetrain to stop. I imagine this is the flywheel effect, being lighter it has less mass to continue its momentum.

The Capricorn rear diff has a tooth less aswell?

This mod is quite expensive, is it really that worth it?
