http://en.wikipedia....Torque_steering
It is something you can feel on a tubby (at least on mine), if you push the throttle for a few seconds, then lift suddenly the gas pedal, your car is going to draw to one side (can't remember which one) for a second.

[techieboy]

I know what it is. I've just never felt it on the VX. Camber and ruts in the road are much more of an issue.

from link ...

Rear-wheel-drive vehicles still are affected by torque steer in the sense that any of the above situations will still apply a steering moment to the car (though from the rear wheels instead of the front). However, the torque-steer effect at the rear wheels will not send any torque response back through the steering column, so the driver will not have to fight the steering wheel. Additionally, almost all rear-drive vehicles designed with half shafts use equal lengths^{[citation needed]}

More to eliminate torque steer I guess.

What torque steer?

You're right, I don't know if it is an issue on all VX220's (usually attributed only to FWD cars), but I wondered if it still an issue on some of the more powerful Turbo's with alot of erm, torque...

[SteveA]

Stage 4 turbo here, no torque steer.

[Glambee]

On my 240bhp tubby with LSD fitted, it does (and wasn't noticeable before LSD fitted). To be more precise : only when lifting the pedal gas at max torque. No sign at max power

I for one have not said it would solve damp/wet driving condition problems ! Each to there own but I think a car is more predictable in any conditions with a lsd

Have you driven a quick VX in the wet with an LSD?

No but like I said earlier .on I drove a Elise S160 with a 190bhp weighing 710kg for 18 months in snow and rain so I know the effects a lsd has. It's all down to personal opinion but I can't think of anything worse than spinning away all your power through the inside wheel on tight corners and roundabouts

I can. Crashing it!

Are you really telling us that you use all the 190Bhp in the snow and the rain?................. Move over Sebastian.

[Sammyturbo]

Rain probably why not ? Snow obviously not but you can use a lot more than without a lsd. I am by no means a good driver does that make my experience less valid ?

[Rosssco]

A 190bhp K-Series has considerably less torque than a VXT or SC engine, and your Elise (sounds nice BTW ) was also considerably lighter, so perhaps traction was in general less of an issue, which may be a major factor in how the car responded to the use of an LSD (assuming a TorSen type)?

ATB qauiffe with a qauiffe straight cut gearset the point I am trying to make is that it's down to personal opinion if you like having a locking diff, I do obviously

[steveboyslim]

On my wish list has anybody got one for sale or no where is the cheapest place to get hold of one

There is a Chinese copy for about £240 but these come rough and ideally need disassembling (some have the gears back to front), deburring/peaning and reassemble with upgraded washers(£12), also they are probably not with the VX corrected ramp angle specific to RWD.

http://www.ebay.com/...e&forceRpt=true

They are rubbish, I can sell you a pallet full of F23 and M32 and those diffs, £265 each delivered (no warranty offered or implied) the company which purchased them now refuses to sell them.
Even dissassembling the and deburring/peaning/freezing and reassembling them they do not work or work for a while and then break.
They make good paper weights though.

Genuine Quaife VX220 diffs £600, diff bearings £15 each, driveshaft oil seals £6 each, oil cap seal £5, fitting £75 while you wait if you bring me the gearbox.
Subject to Quaif's stock level.
There will be a price increase next year.

I've owned a wide range of rwd cars, most with lsd's of all types, all tracked occasionally. .

You can't just say 'they're good' or they're bad'! The behaviour on the limit of traction (not necessarily high speed as stated earlier!) of car with no lsd / clutch lsd / hydraulic lsd / torsen gear lsd are all very different. After this experience I've fitted a Quaife lsd to 3 of my road & track cars in recent years including the VX, with the correct ramp angles which are vital to avoid understeer etc.

IMHO, you don't NEED one for the road, but it's noticeable, helpful and safer if you ever accelerate hard on a low-friction surface (even one wheel on a white line).

On a roundabout or hairpin it allows you to gently and progressively add and remove throttle to balance the car in a slight drift, the way you can't without one. With no lsd, I could only add more throttle until the inside wheel spun and it went back to sliding the fronts out, or go into the corner slightly too quickly and lift off at which point the back comes round sharply and you feel a hero for catching it for a moment, before it goes back to sliding the fronts.

On a track without an lsd the VX has an excellent balance as we know, but only if you enter the corner fast enough as was entertainingly demonstrated to JC on Top Gear when he could only get understeer in an Elise Having the correct lsd fitted simply gives you another option of making the whole car move around in a predictable way on the throttle.

[steveboyslim]

Start a group buy!
I'd be on that list. The VX is my first red car without a LSD, and I miss the ability to do Donuts

PM me if you are interested.

I can get Gripper plate diffs also. Steve

Is the gripper diff more track focused?

I can take you for a ride in mine in the spring time Aimy.

[Duncan VXR]

Gripper a true locking diff unlike the atb stuff. pros and cons to both Have a rwd spec quaife atb diff fir sale if anyone requires it? Dont fit in vag box lol DG
