rich_w 0 Posted January 9, 2006 Hi, I have (with the help of a firend) fitted a quaife that i've had sitting around for a while into my 309 gti. Since i've had the tracking set up at kiwkfit the steering is heavier than it was before. I'm not a fan of kiwkfit (infact my first visit!) and I didnt want to go there but the tracking was WAY out (new dampers & wishbones fitted recently as well) and there was little choice on sunday morning. Is heavier steering to be expect or have the kiwkfit monkey's balls'ed things up?? Rich Share this post Link to post Share on other sites
Jonmurgie 2 Posted January 9, 2006 As the Quaife is an ATB style diff it shouldn't effect the steering until you push it through a corner at speed... I'd highly recommend getting your car booked in at PowerStation as they are the gods of 4wheel alighment and will get things straightened out for you... Saying that, what suspenion and topmounts are you running as with a standard suspension setup you can only adjust tow Share this post Link to post Share on other sites
rich_w 0 Posted January 9, 2006 All std stuff at the moment, I do love powerstation when they setup the car, my other choice is Protye, as PS are quiet expensive, but I would like to think in the next 18 months i will be going to coil overs and then it will be going to powerstation. I need new front tyres very soon too Classic comment from a kwikfit muppet: I had a 309 1.6 injection, i couldn't get a carb for it so had to scrap it.

TEKNOPUG 3 Posted January 9, 2006 Yes, they will make the steering heavy, slightly. They compliment PAS very well as not only does it make the steering a little heavy, the PAS acts as a steering damper when the diff is scrabbling for grip on uneven surfaces.

d-9 0 Posted January 9, 2006 Ive got a quaife in mine, hasnt made the steering much heavier but in the wet its a real pig to drive, as the diff locks in the puddles and mud and snatches the wheel from side to side. fun thou Share this post Link to post Share on other sites

Rich How do you mean heavy - straight line driving , cornering as the ATB will add load though corners and feel heavier to turn Share this post Link to post Share on other sites

rich_w 0 Posted January 9, 2006 How do you mean heavy - straight line driving , cornering as the ATB will add load though corners and feel heavier to turn When ever I turn the wheel it feels heavier, a little more resistive. I think i need to get use to it The car is pulling to the left a little unsure if its the s*ite roads or the monkeys. Share this post Link to post Share on other sites

I think i need to get use to it The car is pulling to the left a little unsure if its the s*ite roads or the monkeys. It will do as it will transfer drive to which ever wheel has most grip. Try going round a corner (slowly) and just letting go of the wheel on the exit. You'll find that it will self-centre the steering and put you in a straight line.

Maerten 0 Posted January 9, 2006 Isnt a differential designed to put most power to the wheel with the least grip? So thats why you change it to a limited slip differential, which will do the same thing but only up to a certain limit. Thus actually reducing the effect, but its still there? (most power is diverted to the wheel with least grip) Please correct me if im wrong, only here to learn Share this post Link to post Share on other sites
Guest ashnicholls Posted January 10, 2006 well that doesnt make sense, Maerten, as why would you want more power to a wheel that is already slipping. an lsd helps to stop the wheel with least grip spinning out. Share this post Link to post Share on other sites

(most power is diverted to the wheel with least grip) Please correct me if im wrong, only here to learn Pretty much. A standard open diff will try to transmit power via the path of least resistance = the slipping wheel (with least grip). An LSD does (should) do the opposite and transmit the power via the path of most resistance = the wheel with most grip.

ellisg 0 Posted January 10, 2006 My brother did a good example of how standard diffs work. He had one wheel on ice, the other on the road, put foot down, the only wheel to move is the one on the ice which just spins. It looks totally wrong when standing there. LSD would have used the wheel on the road allowing him to move off. Share this post Link to post Share on other sites
Guest andy309goodwood Posted January 10, 2006 (edited) the easyst way of understanding a limited slip diff is in the name really it will only diver power at maximum lock up to 50% to both wheels both the one with grip and the one with out thus giving 100% drive to both front wheels at all time so if you get one wheel on say ice on a std diff as above itll just spin and the wheel with grip wont move if you do the same with an lsd fitted the wheel on the ice will still spin how ever the lsd will engage and also give drive to the wheel that still has grip thus pulling the car forward untill reaching a point that the wheel with no grip is able to gain some footing as for steering it should (and this bit is theory as the only car i have driven with an lsd fitted is a 4x4 which is different again ) not effect the stg under light accel or shallow turning circles how ever when one wheel tryes to turn quicker than the other the lsd comes into play and try to drive both wheels at equal speeds thus attepmting to pull the car straight forward regardles of which direction the wheels are pointing in is this is the only way that they can cover the same distance so because of this when making a tight turn on booting it thro a bend the lsd will try and counter the stg thus making the stg feel heavier as you need to apply more force to make the same turn how ever this is all theory atm how ever as i practically fitted the damn thing (while rich went to look for a flywheel lol )i do plan on testing this theory out as soon as he gets some good tyres for me to rip up i also had the goodwood tracked at the same place at the same time and it no longer goes in a straight line so before judgement can be given i would recomend sorting the tracking by some one who has more in his tool box than a pipe wrench and a gas axe (had to go and tell him to back of the goody in the end as i couldnt watch the so called workmanship ) and who the hell has herd of a 309 1.6 gti injection with a webber carb any whay lol (the exact quote by the way ) Edited January 10, 2006 by andy309goodwood Share this post Link to post Share on other sites
madmoog 0 Posted January 10, 2006 Just had an ATB LSD fitted (in a 1.9 BE3 with 1.6c/w for my Mi16 as the previous diff EXPLODED - info for context) and noticed an immediate differance. It is reluctant to move off straight ahead (or initially turn in) but once turning it's fine, but by eck can you put it down early once turning (unless both wheels start spinning).

Sorry maybe i wasnt clear, but i tried to state that thats the way a normal diff works, and a LSD tries to solve this problem Thanks for the link teknopug, but i couldnt find proper exploded views to really understand how it works. I dont know if you have acces to pics like that? Would be great! Thanks so far!
