so what are ur suspension/tire/diff settings right now and on what kinda surface?

It depends on what I want to do:

Drifting:
-Suspension: Stock
-Tires: Hard slicks
-Differential: ~0-5% slip

Racing:
-Suspension: Stock
-Tires: Soft slicks
-Differential: Hard to say exactly, you have to experiment

Both are on a smooth concrete slab.

For racing, i would suggest that you leave the diff loosen a bit. This will help with the turning radius. If you prefer understeering, you can tighthen it, or loosen it if you want oversteer. It's all up to your driving preference.

I've been using a rubber O right from Tamiya's Mini 4WD, just cut it to a desire size and put it in the diff.

Of course you have to have it slip when racing and when you have grippier tires on, or else the car will understeer badly.

As for tightening or loosening the diff, actualy it's the other way around, as you loosen the diff. each back wheel won't have enough friction against the middle plate, so the lost power goes to the front wheels. As you tighten the diff. the back wheels barely slip (or don't slip at all) which causes oversteer. The reason is when turning, the diff. forces both wheels to go at almost (or the same) speed, that causes oversteer.

from my experience you also get heavy understeer with a tighter diff, mostly at higher speeds when you try turning in off throttle. the diff fights to keep the wheels at the same speed. could be a rwd thing.

No, it's not just a RWD thing (it's worse with AWD), you have to put less grippy tires on the back and stickier tires in the front, also moving the batteries to the front helps.

With drifting, I just use hard slick all the way around...the oversteer is essential when drifting with accel off and power over (the styles I use).

So all you do in this mod is replace the bearings in the diff with the washers?

[RC 2NR]

Yeah, basicaly.

[civic freak]

for quicker adjustment i leave the wheel on and just stick my screwdriver through the spokes or whatever you call 'em

to anyone who cares, i have diff plates for sale they're a little pricey but it's because of the material. they are custom machined out of a high temp alloy called inconel. this metal is really tough, they use it on space shuttles and air force jets. the plates look really cool they are 3/8" wide, 1/32" thick, 1/8" center hole, and eight 1/32 holes around the center hole. i wish i had a good digital cam to take a good pic of these.

if u r interested in this product email me at krylonkid@msn.com

btw, to the members of this forum, i will sell these cheaper than i would on ebay. thanks

what would happen if you left the balls in?

EDIT: nice mod. nevermind the question. and the other 2 that i deleted. damn dialup. takes so freaking long for pictures to load.

[geofroley]

She'd get pregnant . You wouldn't be able to perform this mod with the ball bearings.

ahem, im ok now. he he he.

[aperson]

how about putting one in the front and rear? i just got another AWD kit today (front u joints, diff and cone gears wore out) and i was wonering what it would do? just give me even more adjustability right? did you leave the washers that were originally in the ball diff in or did you take them out?

[aperson]

well i did some testing yesterday and this is awesome. i used one in the front and rear, and i tighened them both up well the wooden deck was wet and the thing flew. before this mod two of the tires would spin and the car would go nowhere, but now all 4 tires spin and the thing freaking flies. when it dried up i loosend them up a bit, just enough so that one tire can spin the whole system.

i just performed this mod on my supra. it is RWD and something doesnt sound right. it sounds like the pinion is rubbing the diff pretty bad. since the middle plate is gone, the pinion hits the 3 screw shafts as they come around. what should i do?

[lancer11]

i got a question wat is LSD
