Is this slowboyracing LSD for real?

[98FWDSM]

ok, slowboyracing has a LSD that is only $189....is this the same as the Quaife and will it make BOTH of my front wheels spin? I am just amazed because they are usually around $900 bucks!

Thanks

 

[98FWDSM]

so, if BOTH of my front tires are spinning, this will give me better traction in the rain and snow as well as dry weather.....right?

no, because you are still spinning.


The only thing differnt is you are now a doing a "dual tire-fire" instead of "One tire-fire".

Yes, it will. As long as you don't go intentionally roasting tires, you will definetly have a lot better traction in all weather conditions.

??? read the posts before you make one. There is a lot of info in this thread if you read it.

IS your moniter picking up words mine isn't? I asked about open diff vs insert and you showed me a comparison of an expensive lsd vs insert. I am



Question still stands. If I can improve my handling with 150 dollar insert in my awd vs open diff.........COOL!!!! The comparison is strictly open diff vs insert..................

Yeah, he's definetly hallucinating.

Ok...my first post on this board, and I'll throw in my two cents.

1. $900 for a torsen based LSD? Wow, I'm in the wrong business. These things are built for tons of other applications at 1/3 the price. Seriously, at $900 a pop, someone is making some serious cash.

2. As far as this SBR "LSD" goes, I'm not sure I'd bother with installing something like this. All it does is attempt to (weakly) link the two halfshafts. I can't see how it would be that effective. Clutch type LSDs work on the same principle, but the clutches actually add frictional value to try to keep both wheels spinning the same speed. Metal on metal in a bath of oil isn't going to do much.

3. As far as the torsen LSD aiding in cornering, some of that sounds like marketing hype to me.

sorry man missed the AWD part, thought we were talking about FWD still, just seemed like in this thread the same question was being asked a million times. again, sorry

I don't really trust inserts. I've heard the horror storys of what they can do to your tranny.If I were you I would save up for a true LSD.

Surprisingly, the most common failure of the lsd unit is the user forgetting to remove the two plates and 4 pins that hold the unit together during shipping. THen it flys apart in the tranny and they balme it on the manufacturer. My FWD has made well over 500whp, is daily driven, and see's the track on slicks once or twice a month and Ive never had a problem. If your an auto-xer or like going fast through the twisties, buy the quaife. If your stright line or not into autocrossing, buy the insert.

2 cents.

ok, so this will help you in straight line performance, but wont help you in the twisties. You said that it wont make the vehicle any better during the curves, this may be a stupid question but would it make the car handle worse in the curves or handle the same as a FWD without a insert or Quaife??

Thanks

We have to make the seperation of handling, and handling under power. The car will handle the same through the turns under low to part throttle, depending on the power the car is making. No matter how much power the car is making through a turn, with a quaife type lsd, the power is transfered to the outside wheel and the car will hold its path around the turn and not give in to the lateral g force and enertia. Driving an LSD insert car takes a more "skilled" driver. At the point in the rpm/throttle range when the car is making enough power to break the tires loose, it will spin both tires evenly, much like a locking differential. In this sense, the car will tend to follow the slope of the road and also will be influenced by the enertia of the turn, thus causing the front of the car to drift towards the outside of the turn under power. Both types of LSDs will react similarly in the straight line and through the turns off power. Its the under power turns that are different. You really need to be a performance driver that gives her hell around the turns to need the quaife, and for those of you who do it is well worth the $900+. The LSD insert is just a much less expensive alternative.

Hope this helped

Didn't really know where to put this, and since this is the thread that got me to ask SBR the question, I figured I would put it here. The only editing to the email is the email addresses for my privacy purposes.

Your unit won't fail, no worries.

We machine our own now, that is all.

Since your in philly are you going to the SEMA show this weekend in
atlantic city?

Thanks!

And to dispell all rumors,

We machine our own because B&M couldn't make them fast enough to fit our
needs and we bought an expensive CNC setup so thats are reason for going
in house.

Hopefully this will help clear up some of the controversial issues around here. Later. (On a side note, SBR as always gets for their customer service. I love those guys.)

i have it and it works great...have not had an issue with it I will be soon runnning a 350+ whp set up.....running about 300 wph now.

Best part about it that I liked, was the cut down on the torque steering....

I have a BM lsd insert in my car and it's supposed to be the strongest one on the market because of the stiffer springs. It does work and it does make both wheels spin instead of one but i'd still rather have a quaife instead. The difference between an lsd insert and a real clutch type lsd is night and day. I did not notice a gain in traction with the lsd insert but in a fwd you will still spin like mad. In the snow you will lose traction if your running summer tires. Instead of one wheel being planted while the other spins, they both spin and you hover all over, not going anywhere. I did notice that while in the snow my car will still pull to the right when i'm losing traction. I figured an lsd would make it pull straight, but i don't know. It did help in corning though. Huge 90 degree corners don't make a difference like a quaife would but long drawn out corners like entrance and exit ramps onto the highway, it's a huge difference. For the price i paid i'm glad i have it and i'm sure it will work much better with stickier tires like slicks, but if i had the money i'd do it right.

doesnt locking the wheels cause the outside tire to turn faster on cornering, causing the outside wheel to break traction? so really isnt it kinda an lsd eliminator, and thats why it improves straight line proformance and not turning abilities?
