uprated diffs mk4? - R32OC

eatthisvr6 · 4th October 2008, 08:18 AM

what are the options for upgrading the diffs on a mk4 ie torque biasing jobbies etc
who makes em and how much are they?

Hiya, which diff are you talkign about the front or rear?

There are basically two comapnies that do them, peloquin in america and quaife in the uk. Quaife is more expensive as you need to get the bolts etc as extra as they come with the peloquin kit, but then there is the backup help from quaife being a uk company.

Well here is the info about the quife front: Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential - Quaife Engineering

Quote:

Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential
Product code: QDF14R
Catalogue Page: 10
Manufacturers: VW

£612.85 (Unit price exc. VAT)

Technical Drawing Quaife ATB Helical LSD differential for Volkswagen Golf 02M 121C 4WD 6-speed is suitable for Volkswagen Golf models with 02M 6-speed 4WD gearbox. A direct replacement for the standard Volkswagen open differential, the Quaife ATB Helical LSD differential transforms your car's performance.

Unlike a conventional plate-style limited slip differential, the Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.

The Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.

The Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.

The Volkswagen Golf 02M 121C 4WD 6-speed Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.

With over 170 applications, the Quaife ATB Helical LSD differential is second to none. Accept no imitations!

Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment.

The Quaife ATB Helical LSD differential for Volkswagen Golf 02M 121C 4WD 6-speed is also now subject to a lifetime warranty (subject to terms and conditions).

but you would want this one: Volkswagen Golf Mk4 2.8 V6 4Motion front Quaife ATB Helical LSD differential - Quaife Engineering

mines got the r32 gearbox not the 4motion is the 1st 1 for the r32? i assume the rear diffs are identical?

pomme · 4th October 2008, 08:47 PM

I reckon you would be looking around the 700-800 mark for each one without installation.

eatthisvr6 · 4th October 2008, 08:52 PM

bugger deffo cant get both then :( which would make the biggest difference ie remove understeer the most (the suspension and arbs do a good job as it is but id like it even better)

StuOwen86 · 4th October 2008, 09:03 PM

I was asking about these at APS today and they said not really worth it unless Forced Induction because of how exspensive they are to buy and also fit. Dunno exactly they are too fit tho he said it would be quite alot tho.

Stu

mars2 · 4th October 2008, 09:13 PM

If you want to remove understeer fit LSD on the rear.

Nice im hoping too force feed my .:R some fresh air in the near future, just getting all the other bits done 1st so im ready if need be, I have just had my Tarox 10 pots done and the KW V3's ect.

Stu

eatthisvr6 · 5th October 2008, 12:04 AM

our cars are evolving along similer lines fella

iv got kw v3 along with nuespeed arbs iv got uprated disks waitin to be fitted along with porsche 993 calipers iv got a mk3 golf vr6 charged which is 320 hp ALOT faster than the r32 atm im selling it to charge the r really wish i didnt have to though

pomme · 5th October 2008, 09:05 AM

yeah for understeer you want the rear but for better traction you want the front. If you are taking out the box to do a clutch which im sure you will be with that amount of power then to save alot of labour charges, ie at least 6 hours, then i would do the fornt when the box is out as the rear is pretty easy to do.

eatthisvr6 · 5th October 2008, 09:11 AM

cheers for the help AGAIN pomme im annoyed i cant get both i may not be able to get any lol wonder how much 60gig ps3 are goin for i could sell mine
would the rear diff be better for 1/4 mile due to weight transfer (bear in mind my haldex controller is instant 50/50 split)

pomme · 5th October 2008, 09:19 AM

you got a mk5 then?

eatthisvr6 · 5th October 2008, 05:37 PM

no got the competition spec controller it works off throttle position and goes instantly to full 50/50 torque split

pomme · 5th October 2008, 05:57 PM

the blue, orange or haldex race controller controller (not the one that is sold by the likes of vagtech, aps, tt shop, awsome etc the one that there is only like 100 in existance)?

Alex303 · 5th October 2008, 06:17 PM

The TT-Shop don't advertise the Haldex 'Race' controller but last time i checked they will sell them if you ask, several were sold in the GB that ran last year.

They don't like selling them to people who are'nt racing their cars though and don't really push them for general road use.

yeh its commonly called the orange controller because hpa (i think) paint em orange psi tuning in stoke can get em to order

burrell48 · 5th October 2008, 07:09 PM

So what controller would you guys recommened i'm runnin 350 bhp and do a few track days.

CHeers

pomme · 5th October 2008, 07:12 PM

Ahhh okay, well that isnt a 50/50 split from what i understand as im pretty sure the maximum it can transfer to the rear is 40%. But yes you are right basically hpa managed to find out a way to reprogram the controllers and that is why some of the orange controllers the orange pain peels off the reveal blue.

I reckon that a front one would be better if you are more keen on drag racing to help get hte traction down, and it certainly does help through the twisties

eatthisvr6 · 5th October 2008, 07:12 PM

as above lol
