This is about as classic as it gets for me.

 

With regard to LSD, has anyone here any points of view on it?

I mean driven a car with versus without

 

 

I have no idea what the "Quaife A.T. B. lsd" is, I have read up on the theory and application but just wondered what the pros and ( if any) cons are?

Thanks

lsd = two wheel peel vs peg leggin!

what is it registered as ?

Cons:

Expensive

Some people prefer other types (as an example, I prefer clutch types)

Can make the car unstable during lock/unlock (not normally a problem though)

Can cause additional noises/chatter from the rear end, especially around low speed tight turns (parking lot). The noise depends on the type and setting of the LSD.

 

Pros:

Allows you to gain better traction out of corners

Allows for proper power slides

 

I've driven a 7 without one and it's almost a crime. Due to the limited weight over the rear axle in a 7, it's really hard to get traction - especially when the inside tire simply wants to lift up and spin.

I haven't driven a seven back to back with / without but my Caterham has the same Quaife model in the ad, and none of my previous sports cars (MGB, 240z, Miata, 928) did.

 

In a car that has enough power/torque to require judicious application of power coming out of corners and not just bury it, the LSD does help control the back end when you get wheelspin. It's not a magic bullet, but it does help you keep the car moving forward instead of sideways.

 

On a car with not a ton of power (like my MGB) I don't think it would have made a lick of difference. On the 928 it could have helped. In my seven which is around 200 horsepower it is really easy to break the rear end loose and I can definitely feel the torque shifting back and forth between both rear wheels.

 

Quaife is just a brand name - Caterham sold

He's an article Craig Taylor (now retired) did several years ago about differnentials.

As far as I know there are four types available for the Sierra 7" diff.

 

Open of course (no limited slip). You can manage your traction with the suspension. Eric Prill almost won a national championship with and Lotus 7 with an open diff....by limiting droop in the front suspension. But that was a low torque car.

 

Cam and Pawl. A lot the limited slips in Caterhams especially older ones use an AP Suretrac which is this design. I really works ok. Unless you making big power they are pretty dependable in a Caterham. Almost all the cars delivered from 99-2002 for the Caterham Championship Series had these.

 

Clutch type. These are Lockheed or Titan. They do have clutches that wear, but from what I understand the Lockheeds last forever.

 

Torsen (ATB) Quaife uses this....and it is a widely used, trouble free and quiet design. There are no friction surfaces to wear. Mazda has used it for the Miata LSD's since 93 and they take a huge amount of abuse in Spec Miata. Only downside is they are a limited slip until they aren't. If the inside wheel becomes too lightly loaded (I think the article says 20%), the mechanism directs the power there. I think there was been some work done to minimize this. All around it is the best choice for street usage, and the limitation doesn't seem to keep people from hustling around Spec Miatas pretty quickly.

 

I would say the fact this car has a Quaife is a pretty big positive. It should not be any noisier or require more maintenance than an open diff, but provide a substantial improvement in traction.
