has anyone ran a locked differential or welded for drifting? Its alot easier to control with alocked diff, you get power to both rear wheels and more stability and control drifting. But has anyone tried this on their fc? My friends that skillfuly drift 240s do it and was wondering if anyone has tried this yet on the fc. Im running lsd right now, but have a extra open diff, Im thinking of welding it butIwanna hear what u guys say.

 

i have one on my fc I just got it.. yah you can drift on it, even tho right now i dont, just daily driving.. I had a nismo 2 way lsd in my old s13 and i loved it so much more.. I had a little more confidence in it with touge/canyon driving and daily driving... the welded i hate it becuase its like the only thing you can do is drift, I like grip and cornering hard and getting on the throttle feels like the rear is gonna step out.

Theres a few guys rockign welded in thier fc tho and would have more knowledge about it.

 

im working on getting some mazda speed lsd's, ill let you know more info, when i get the price and such

 

If this car spends any time on the street, don't weld or lock the diff. It's stupid and dangerous.

 

+1

amateur canyon carving doesn't count for much in the "grip" driving world.

 

too much talk from people with no welded/locked diff experience.. appreciate your guys input but your replies dont really contribute to the topic. thanks

 

Do not weld it.

 

I will withhold my opinion on drifting, but I would like to know exactly what part of the diff is being welded? The spider gear? I've seen in mentioned many times on here but I don't really see why its done. It is inherent that the rear wheels rotate at different rates when the car turns. I've heard of diffs that lock after a certain amount of differential rotation, but if you altogether prevent the differential from allowing the wheels to rotate at different speeds, how does that benefit you?

 

I have had experience with a welded diff on the street (not mine), and it was stupid and dangerous like I said.

 

Makes the car understeer at light throttle and oversteer easier upon power-on due to loss of traction from the wheels forced to spin at the same rate.

It's a plus for drifting.

It's absolutely dangerous on the street, in traffic. Unless of course, you don't like to drive your car spirited on the street, and are able to control yourself and drive really slowly.

You can do it if you want, and it may work for you, just remember, you are taking a risk with your car and the cars around you.

IMHO, you should do it right and just get an S4 LSD, which is a clutch-type. All of the benefits, none of the drawbacks.

 

Welded diff:

Stupid on street, as mentioned above.

Fine for a full time race car. Chassis tuning is different but not much, if your drifting it will help if you have the power.

Spools are used all the time in race cars, in fact, any serious endurance car will have one. Remember the IMSA GTO days, Roush Mustangs, RocketSports Oldsmobiles etc. they ran spools for the 24hrs at Daytona. Why? An LSD generates heat and is something else with a bunch of parts that can break. And if you break an axle you can still get back to the pits pretty quickly.

 

Why not just run a viscous diff then?

 

what kinds of viscous diffs are availble for the fc? Is it oem? or aftermarket?
my buddies daily drive a welded diff. He drives just fine and can even canyon run with it,the only thing is he screeches when he does u turns, or slow turns, and ppl are liek wtf?!?! until they see him drift theyre like omg.!! His 240 is like explained when you gas it into a turn itwill have TONS of steering and power, but if u let off the gas ina turn it understeers. its really easy to kick the rear out in a turn. He drives just fine in the rain too. actualy WE LOVE THE Rain lol you can swang without loud noise and killing the tires and drawing attention.

well il give it atry, I have both a s5 lsd and a s4 open diff, Ill weld the s4 open diff... and iff its that bad il switch back to lsd

 

it will benefit more stability and control drifting. It puts more power to the wheels, making it easier to kick out. you have no powerloss oneitehrwheels thisway.

 

Yo, which model S4 offers the clutch type LSD??? Im running freewheel S5 na diff on my GTU TII swap and want something cool n cheap for right now. Do I just need the gears and is it all plug n play???

 

Viscous NA diff = S5 GTUs
Clutch-type NA diff = 86-88 GXL, 88 GTU and some others, you guys should really read the stickies.

 

welded diffs are fine on the street. if you feel that its dangerous on the street. ever stop to think maybe you are why its dangerous. Many drag car get driven on the street with spools out by me. no big deal. if you can be mature about it nothing wrong. same goes for guys who have 700hp supras who street them. nothing wrong with unless someone gets in over there head. once the car is rolling forward. you won't notice unless you are like below 5mph. I had a nismo sss shimmed and packed with discs to be essentially a spool. it would pop and clunk. I would rather the tire gives plus you get to make a swisha sound.

 

I can show you a broken stub axle from a welded diff that was driven on the street.

Sure you can drive on one street safely but it isn't always the tires that "give" in a tight turn. CV joint will go as well.

 

I prefer using a welded diff over a visc/clutch type, i think its just a personal opinion.

 

And it only costs about 25 cents of welding wire and 15 cents of electricity to do!

 

low stuff welded is good for practice. but fc diffs are not the easiest to change. i would hold off till you get a t2 diff. repack the clutches.

under highspeed corners the fc will under steer so hard with a welded.

racing aint cheap

 

OK if your broke go WELDED
If you have some change go for STOCK LSD
If you got a job Buy a kazz or torson

 

cusco ftwmf'ers

 

How is the fc's lsd any more complicated to replace with an after market clutch type than any other car? I'm about to switch over from ae86 to fc and it wasnt too easy to do the swap in the corolla. We had to pull the axles out (solid rear end) and drop the entire rear end, then pull the stock lsd out. If you are going after market 2 way does it matter if you start off with an s5 or s4 diff? Same end result, or is one stronger than the other?

 

Same end result.
