LSD

[Matt@Stealthsport]

Hi

I am thinking of getting on of these for my Trophy but wondered who has used one and what differences its made?

Also are there any differences between say Quaife and any other makes?

Cheers,

Matt.

I've never driven a Clio with one fitted, but i have driven an EP3 Civic R and a few DC5 Integras, with the LSD. And also a Civic without one.

It makes a big difference IMO, or at least it felt it! You can get on the power a lot sooner ion tighter corners, without the annoyance of spinning it away on the inside, unloaded wheel.

There are down-sides though. The LSD car i drove had a Cusco diff, and was noisy at low speeds, especially when you had a few turns of lock on. Also, pulling out of junctions using the power, i felt the car pull the steering to centre a lot quicker. So that could catch you out too.

Sounds more fun tbh

Noise wise is it a whine?

as christarse says really, very good contraption, but ive learnt my car and am happy with setup, was gonna get quaife but decided against it.

the one on the R26 can throw you in snow/rain if you push it, but in the dry its a good addition

 

[MistaT]

Quaife diffs make the car pull all over the place on uneven roads, and feel quite strange if you aren't on the throttle in corners. It's definitely a weird sensation to start with. Great for getting power down out of corners though, and more so in the wet. Going from a diffed 106 to my trophy in the wet is very weird.

 

[drhowser]

i have a quaife waiting to go,

as far as i am concerned, look at the r26. every write up you read raves about how much of a difference the diff makes. it must be worth doing for a track car?

 

[Christopher]

No, more like a clunking. Like worn bushes, kind of! lol

Quaife are quieter and less aggressive that the Cusco i drove, that was pretty brutal. Pull you everywhere on rutted roads! I liked it though, in a weird way.

Jo3y has the same Cusco on his DC5... and he thinks the same

 

[drhowser]

the cusco is a plate diff i take it?

 

[Christopher]

Yes, plate diff

 

[drhowser]

definately more of an animal then!

 

[Christopher]

Yeah, rated for road use though.

Although it clearly means smooth Japanese roads, rather than our sorry excuse for surfaces

Go balls out and get a Sadev Seq

Hi

I have a plate Gripper lsd on my Williams, it is also lowered on stiffened koni's and has a strut brace and negative camber. It can be a bit of a handful on bumpy roads and it's loud (sounds like a bag of bolts on tick over and whiny like straight cut gears!) but I love it, traction and handling is amazing. I have driven it with this set-up for the 4 years I have owned the car with no problems, and the previous owner used it as a hill climb and sprint car, so it has taken some abuse! I also used it as my every day car for the first 2 years!

I always say the same thing about them though, unless you use your car for competetion or are a serious track day enthusiast I wouldn't bother as it's an expensive bit of kit and you wouldn't really see the benefits on the road unless pushing hard (which I do regularly!) it also needs an overhaul every few years to check for wear etc. my Williams just happened to have one fitted luckily!

 

[LeeJSA]

I've recently fitted a Gripper LSD to my track Clio 172....its a proper handful on the road in certain circumstances really does pull you all over the road if you're not careful you've got 2 have your wits about you!! Its a little bit noisey & feels like a CV joint is fubared on full lock slow speed manouvers....BUT....on track its an absolute godsend...I love it - probably the best mod I've ever done on a car for track purposes anyway!!! Well worth the money & time I waited for it!!

 

[broster@JAM-Sport]

a quaiffe ATB is a good all round diff.

 

[Russ Rallye]

Does anyone else make a plate diff for the 172? Where did you guys get your gripper diffs from, would prefer a plate diff personally over the quaife but for all round road and track use ATB would be a good compromise. I assume the diffs for 172's etc are expensive due to it all being one piece with the input shaft in the box?

Avanti use ZF plate diffs. These are very good units.

More expensive than gripper, but alot more adjustment on them if your into competing.

Whereabouts in Carlisle are you from pal?

 

[Tony Hunter]

To be quite honest Matt I would not bother.Its alot of expence for very little gain,our times around the Hungaroring changed very little when we had the diffs installed.But to have if you've got the money spare.

 

[Jo3y]

If you're doing a lot of driving around town a plated diff can be a bit of a nightmare. Pulling out of junctions it's incredibly loud and not exactly smooth, the same applies for driving in slow traffic and using the clutch a lot. As soon as you're giving it some round the twisties though it's all worth it, you can really feel it pulling you through the sharper bends when you're booting it. Mines a 1.5 way diff as well so it digs in when letting off. Just make sure you've always got a firm grip of the steering wheel, I've only made the mistake once when pulling on to a wet motor way, putting my foot down and nearly switching lanes :S

 

[Russ Rallye]

Stan, did a search for avanti diffs, just couldn't find much info on suppliers etc. I live near wigton just outside carlisle btw.

Sounds like a good idea to have.

With the roads being so greasy recently, I've been getting rediculous amounts of understeer even when feathering the throttle around corners.

Why tyres you running mate, i've only had bad understeer once this winter thats on budget tyres aswell (mistake buying them).

I know you have, erm, 105bhp more than me buy surely it only makes as much power as you put your foot down.

 

[Icarus]

I'd shy away from any plate type diff for road use. Yes we use them on the race cars and yes thats one of the reasons why they are so quick but they are an absolute s**t to deal with on a road car.

A Quaife ATB type diff however can be very, very handy on the road. It needs to be specced correctly though in order to avoid the original spec Focus RS issue.

Done properly you'll lose very little and gain a lot!

There is nothing to spec on the quaife diff, there is no adjustment at all. The issue with the focus was not the diff it was suspension geometry.

more of a bush issue really, fit some uprated bushes on the bottom arms and most of the issues went!

 

[Fred@BTM]

gripper! noisy bugger, but awesome

 

[stan*]

Plate type LSD's are inherently noisey..

 

[Fred@BTM]

you don't say! sound's like the box is knackered when running a gripper

 

[George k]

Gear type diffs - as per Quaife can have different specs, depends mainly on the angle of helical on the small gears, which will affect the amount of locking.

 

[stan*]

But its not an optional adjustment from Quaiffe, is the point being made.
