Post by: tomolambo on December 17, 2014, 04:46:03 pm
I have bought a lsd and am getting my gearbox overhauled when it is getting fitted.
The company i am usung to do all the work has said i need to de-ativate the traction control ones it is fitted, I think he is chatting utter bollocks but i just wanted to make sure he is incorect.
Am i right or is he?
cheers tom

No you don't have to disable it. It may hold the diff back from working properly, but you can either turn the TC off when driving enthusiastically or get the TC mapped to work with the diff (not sure who can do this - maybe R-tech)

Thats what i thought as the traction controll just kills the power it doesnt apply the brakes

For me there all just as good, haven't really seen any negative reviews, I ended up going for a wavtrac after a friend's recommendation

2nd for Wavetrac, amazing on track. I've no experience of others though.
For me it cured torque steering issues and is very smooth and progressive in it's function.

It's fair to say that they are probably all vastly superior to an open diff.

It's a big job and complex so maybe place confidence in your installer above the cheapest price and use a local company possibly?

Quality over anything else when it comes to LSD fitting. Get it wrong, bye-bye gear box. Give AKS Tuning a call, there's a group buy on right now for LSD as we speak (I think)...

Maybe I am chatting rubbish but my old mechanic told me that Wavetrac's are always working even at low speeds where as quaife and the likes only work when you are pushing along a fair bit. I went with a quaife in my previous car as liked the idea of British engineering with a lifetime warranty, plus I figured I would only need the benefits of a slippy when pushing it so the wavetrac was irrelevant.

I know that the Wavetrac is supposed to more progressive in its engagement and others can be noticed when they engage. A little more like an on/off switch.
You may well be correct in what your mechanic is alluding to.

Can't speak for the mk5, but I had a diff fitted to my old mkiv gti. This car was an early model, AGU engine, and I had fitted a K04-23 turbo and all supporting parts, so was effectively an S3/TT engine, but mapped to 250+ (no idea on exact figure as I never had it on a dyno before it was killed by a 1-series).

From my experience - the Quaife diff absolutely transformed the car. As it originally had no TC and was throttle cable, whilst it was nicely controllable under foot, the engine could still spin up the wheels in the wet or dry when deliberately provoking it.
On my first drive after the diff was fitted, the traction was transformed - it was after a rain shower. The car just dug in and got on, whereas before it would have scrabbled, understeered, and spun the wheels until letting off the throttle, or traction was gained.
All this was at low speed, out of junctions and going round mini roundabouts. I never had the chance to go on track to test high speed cornering changes before the car was killed, but I do disagree with the comment that the Quaife is ineffective at low speed, as in my experience, it simply isn't - it is amazing. I had to learn a different way that the car drove...

In ten years of ownership/modding my mkiv, it truly was one of the mods that I said to myself 'why didn't I do this earlier'.
