Hi,
I'm looking to put an LSD into the 02R 5 speed in my vw Polo 9n3 gti. I have a couple of questions that I don't believe have been fully answered in the other threads that I was hoping to get some help with:
1. torsen/helical Quaife ATB vs Peloquin vs Wavetrac. Now from what I can gather they are more or less slight variations of the same thing. Peloquin say that they have shims that can pre load the diff and wavetrac do something similar in an effort to try to fix the inherent flaw where an unweighted wheel will cause the diff to go into open diff mode. So from an engineering perspective there's a point of difference BUT in practice, can anyone who has owned and driven them compare these 3 torsen types and tell me if there is a noticeable functional advantage that the Peloquin and wavetrac have over the Quaife or is it a situation where if you weren't told what you were driving you couldn't distinguish them.
2. Am I right in assuming that all these helicals are considered 1.5 way LSD's?
3. With regard to plate/clutch diffs I have managed to find a KAAZ :
and an SQS:
SQS Racing | LSD SQS 02J/02A/02C/02S
The KAAZ is a 1.5 way but the SQS is a 1 way.
From a performance point of view can someone who's had experience of them comment on how the 1 way would feel compared to the 1.5 way? eg I love late braking and like to trail brake deep into corners. Is the 1.5 way going to create more understeer compared to the 1 way in that circumstance? If I did the same with a 1 way, when I did get onto the power would the locking be more or less abrupt than the 1.5 way?
4. Also with regard to wear I assume plate/clutch diffs will only wear when they are actually forced to lock up. Although they may wear on the track, on the street they should last as well as a torsen shouldn't they? My car will do up to 12 hillclimbs and 2 or 3 tarmac rallysprints a year but will also daily drive. So whats the low down on wear/maintenance for clutch/plate diffs versus helicals in street/track applications? Once that diff/flywheel/clutch etc goes in I don't intend on doing a gearbox again in the life of the car if I can help it if that explains where I'm coming from. Does the mostly street driven situation force me toward 1 or 1.5 way or from a wear point of view or low speed maneuvering point of view?
tonne of questions I know but very keen to hear what people have to say about the two regarding wear/maintenance and also 1 way versus 1.5 way.
thanks
