I'm planning on getting this LSD but given that I'll have to get it shipped to Turkey and pay a lot for shipping & taxes, I want to make a good decision. I'm more of a spirited driver than in any way a track addict. That said,

1) How's the straight line traction esp on wet conditions and uphill? One major problem I have is that the front wheels on my MCS loses traction easily (& the DTC kicks in) when I have to get a little aggressive uphill or when the road is even slightly wet. The tires I'm using are not the issue, I can say that.

2) How does the car behave when you start to lose the rear end and have to correct it with the throttle?

3) How does the car behave when you start to lose the front end and try to (normally incorrectly) turn the steering into the corner and throttle? Does it still require to ease up steering or does it just grab & go into the corner?

Thanks for all the help in advance..

 

dear eg3,

I will comment, based on the 145,000 miles that I have on my Quaife.

1. straight line traction with the Quaife depends on the tires. The Quaife applies power to both front tires equally. When I am racing, I normally leave the starting line with both front tires spinning for the first 10 feet or so, and there is no pulling to one side, no drama at all.

2. The Quaife does not change the way that the car reacts to throttle in the middle of a corner, unless a large throttle opening is used. With large throttle opening before the Quaife the inside front tire would spin and not much else would happen. With the Quaife the car will accelerate as hard as the available traction permits, and understeer if there is more power than traction. Tightening the line through the corner by closing the throttle a bit works the same way with and without the Quaife - no change.

3. The Quaife helps the car turn in a great deal, so where without the Quaife the car might push (understeer) through a tight bend, the car will do much better with the Quaife when entering a hard corner with some power applied. It isn't magic of course - if there is way too much speed then the car will plow a bit until there's sufficient traction.

I recommend the Quaife without reservation for competition, and for daily driving with poor traction. It works very well, and has proven perfectly quiet and reliable in its operation.

Hope that helps,

Charlie

 

Will it give huge improvements even over the Factory Helical LSD?

 

I wish the factory LSD was helical. It uses friction cones if I recall correctly.

factory one is alot better than none but i can still over power it very easily. the car does turn in a lot better and through tight fast corners it works very well. in tight slow corners you can still spin the inside tyre if you are too heavy with the gas.

 

I don't have a Quaife in the Mini but I had one in my last FWD car. It was turboed and put down around 300 HP/TQ to the front wheels.

1. In a strait in the dry it improved a bit, in the wet however Id say it about doubled my traction, if not more.

I never really noticed A change in the behavior in any over or under steer conditions.
