OK, so who's thought about it or done it? what are the complications apart from the obvious or is it simply a case of dropping out the box opening 'er up, taking the diff out and have it converted into a limited slip diff?
Is the rear diff 4.1 ratio ??

Would this relatively simple mod (although not cheap) but relatively easy to do, help cure this thing called understeer!

Thoughts please,
Cheers

 

Someones already done this.It was either Moray or Adam M I think.

 

Not sure about my answer at all but doesn't the ABS stop you from doing this?

 

Ratio is 4.444:1

 

The ratio depends on what vehicle you have but you have not given enough information. Diff ratios can be 3.9, 4.11, or 4.44. Fitting a front LSD is relatively straight forward but it needs someone who knows what they are doing to set it up. Obviously it involves taking out the gear box. Providing you have the bits before you start the job, start to finish could be well before lunch. There is the option for a torque bias LSD or viscuous.

 

If its a P1 as you say, it should be a 4.444 front and rear, although diff ratio is irrelevant for fitment of an lsd.

 

What make? What price, anyone?

 

Contact Mark @ lateralperformance....he can sort you summat.
I've got a Modena torsen style diff up front, and I do think it's a great mod.

LOL @ hoppy.

I have a quaife atb in my gearbox, though no torque has been put through it yet.

If you want you can buy the gearbox lifted out of my 22B.

This has a 4.44 final drive but is also the type R short ratio gearbox and already has the standard limited slip front diff in place.

I am fairly certain it was a viscous type front diff rather than an ATB type made by modena or quaife so it is likely to give you different handling characteristics.

As stated above, final drive doesnt matter if you put the crown wheel you took off onto the new diff.

My box is pre built with all the bits you want already in place.

If you were to buy an lsd separately (500-600), you would need to remove and strip the box down as the front diff is the first thing to go in it.

Would be interested to buy your gearbox, what are your thoughts on how much you want? where do you live?

email me on adam@22b.com

I am in london, but the gearbox in in surrey!

 

My STi5 TypeRA has a standard fit mechanical front LSD. Aparantly STi installed 2 types of front LSD in the TypeRA, mine is the latest type.

 

Thanks for the info john,

have no idea which mine is.

my car is number 377/400 so its one of the later version 4 type rs and as such may have been chronologically close to the production of your car.

I have no idea which type of front diff mine is, only that it is an lsd.

I presume it would be a viscous type.

 

Ahh, Mark Again (I think that's how you spell his name He seems to have all the best toyz
