Limited Slip Differential review, owners please comment

Has anyone else got any experience they can add to this? I've rapidly gone from standard LCR to stage 2 and have sorted out the handling to match the power. However I think a ATB such as the Wavetrac would be a valuable addition. I've seen it advertised in PVW for around £665.

What sort of prices are people paying for an ATB / LSD, do you guys who have bought already have any links of the Diff's and the necessary fitting kits? I gather the LCR225 has a FML Box also?

The LCR is an FML 02M gear box.
£665 is a good price, but you'll need the fitting kit OEM one £100 APR one £150.
I've read recently of a very high powered Edition 30 with the same diff too.
 
I asked the guy who was fitting the diff which he suggested and he said either.
So I got the fitting kit from David at Seremotors, of course :)
 
Can I ask what an FML box is? Is this better than other boxes fitted across the VAG range? Also, how come you can buy a differential fitting kit from SEAT even though an LSD was never an option? Sorry, I have no idea and I want to feed my mind :)
 
Well I believe that the MK5 Golf GTi came with both but I am not sure if the MK2 Cupra got independent rear suspension.

I like the LCR as it's kind of raw & refined at the same time but there's much room for improvement. For instance, the cave-man rear suspension can be made good with a decent shock/spring package and ARB (but that's a whole other discussion) and at least an LSD can go into the box without too much hassle.

the fitting kit is to fit the differential to the final gear, which is in the OEM box attached to the OEM open diff.

so the LCR doesnt have LSD as OEM?

No, open diff
 
I am looking at getting an LCR and have currently got a Megane R26(for sale if anyones intrested)which have a GKN torque biasing diff fitted as standard and its brilliant they have so much grip you can get the power down really early and the diff just pulls you round the bend with no understeer what so ever,i also have a Proton Satria Gti and 205 Gti rally cars fitted with plated Lsd's and they do the same thing but you have to rebuild the plated diffs cos the plates wear out so not ideal for road use and can be a bit more agressive(more suited to competition cars)but the beauty of the torque biasing diffs so i am led to believe is they never need servicing so are fit and forget,definately a costly mod but is well worth it in my opinion
Think it was Evo magazine that tested the Civic type R championship white that has a LSD as standard and it was a few seconds a lap quicker than a standard CTR round the track with the diff being the only difference

Anybody got a LSD on a Cupra?

Seem quite pricey but very effective where the Leon usually lacks the bottle in cornering etc. My mates MG ZR corners a lot better than my LC (but it's still a rover....!):lol:

RobDon has a diff in a LC

this thread is a money pitt!!

This will probably be a silly question, but does a diff help straight line acceleration at all?

I don't think it does, I don't have any straight line acceleration difficulties with my set up and running 1.6 BAR of boost

Would have thought so as its helping the car to get more grip and putting the power down more effectively,definately helps from a standing start

not too sure about standing starts either, massive difference in cornering.
If you break traction due to power or wet the diff makes it a bit more scary as both wheels are spinning giving you no chance to steer.

But both wheels would be spinning on a car without an LSD and surely an LSD stops the wheels spinning?might depend on what power you are running and what diff it is but ive never spun the wheels in any of my cars with an LSD,did a test the other day with the rally car on gravel and it just gripped and was away where as before the diff was fitted it would have just sat there spinning for a few seconds

LSD just means that a equal amount of power is distributed to each driving wheel, it doesnt mean its any harder to spin the wheels.

Na, a car with an OEM open diff favours the wheel with least traction.

Take a powerful car on a flat piece of road and rev to 4,000 RPM's and dump the clutch, you'll make one long line with the spinning wheel.
Do the same with a LSD fitted car and you'll make two long lines.
This is for ATB LSD's, plated and fixed is a VERY different story.
You rally car will not have a ATB LSD, more likely to have a fied or plated one
