Hi,

I'm looking at upgrading the lsd on my r33 (as it no longer works) i've worked out which brand i will be buying (NISMO) but i'm not sure weather i should go for a 2way over the 1.5way.

The car is daily driven, and most of the track time i see is grip events but i dont mind a drift event here and there. Is there any major loss in going for a 2way compare to the 1.5way?

CHeers Michael

well a 1.5way is still a 2 way. just weaker on deccel (which is good unless you like backing it into to corners all the time). up to you. if you are hard core into drift then a 2 way is the go.

hmmm, what do you mean by backing it into a conrner?

will i have more chance of braking traction with a 2way into corners ?

1.5way for a street/track car <-- I use a Kaaz, and it's great!!

2way for drift only car

I have heard of too many accidents with 2way diffs on the street.

Under acceleration both are equal, but under deceleration the 2way will lock just the same as acceleration but the 1.5way requires more force to lock the second wheel. This 1.5way allows you to coast through round-abouts and turn corners easily without having to take it out of gear.

thanks for the reply Al,

i was abit worry about the 2way lsd as i've driven a 86 with a 2way kaaz and i found it extremely easy for the rear end to come out when turing but i wasnt too sure if it was just the lsd or the car setup

a 1.5 way is much better suited to track work (for ameture track work) because they dont lock up as easy under de-acceleration but remember you have a certain amount of clutch/shims you can put in the diff (the clutch packs for the lsd) to make it stronger/ weaker in its lock up . there wouldnt be alot of difference in them if people knew how to set them up properly :D (on a side note, did you know that v8 supercars use a full spool) , it comes down to your driving style/skill in the end for the decision

Under acceleration the 1.5way and 2way lock up at the same rate: Provided they are the same make and have been set-up the same, with the same amount of shims.

The difference is only under deceleration.

Do you drift exclusively? No, then get a 1.5 way. Yes, then get a 2 way.

If you get a 2 way and you track your car then you will be driving around the diff on corner entry as it will unsettle the car in anything but a straight line when braking/decellerating. Which means any corners where you have to brake in a curve, arse end tries to come around so you are backing it into corners as Beer Baron has already stated. It's great if your car is an understeery pig as it gets the nose in, but otherwise just a pain.

For occasional drift the 1.5 way will do the job. It just means you need to initiate the slide a bit differently. Plenty of guys drift with 1.5 ways.

i hate the kaaz diffs, bear in mind if you buy a decent diff many are 1.5way and 2-way switchable. CUSCO for example do this and NISMO also has the ability to do this and to tune the torque preload WITHOUT removing the diff. i hate the whole kaaz feel and design.... just in case you missed i the first time :rofl:

I totally agree that the Nismo diff is better. But i got my diff from an Australian supplier at a very reasonable price (fair bit cheaper than Nismo) and it does the job VERY nicely.

Agreed. Got mine for $800 new and its good enough for my thrashing around...

I havnt driven it cos I ripped my achillies and on crutches for ANOTHER 4 weeks... no deca driving for me, will come down though Al with Alan.

      I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
