Because if it's performance you're after you're better off just buying an Abarth in the first place... >

abarth is not available in my country but i can get an lsd with shipping. because there is no other aftermarket lsd solution for fiata.

I think it's a reasonable idea. However as I haven't actually done it yet, I can't be certain there won't be some unforeseen complication. There often is...

thank you greg. also what do you think about aftermarket lsd support for spider? will it be soon?

I do think it will be soon, but I don't know for sure.

Oh that's a shame!

It's been done in the ND, but that doesn't mean you can extrapolate such work over to the 124.

Anyway, you might find this of interest:

In Aus, the Miata range also gets LSD as standard on all models except the 1.5 auto..and obviously Fiat only sells the LSD equiped Abarth version here. The BRZ and 86 also get standard LSD except the base model Toyota auto.

Every performance car (FWD or RWD) should have it in my opinion. Although curiously, Lotus don't think it's necessary on the Elise (even in 220+hp mode...although it's an option), and McLaren famously eschews it on their cars for an electronic brake steer system (which is hard to fathom).

I agree, it can't cost that much, I don't understand why they don't include it.

Alfa does something similiar on the 4C. it doesn't have a mechanical LSD, but uses electronics to sort of simulate one.

I've never driven an electronic system that works as well personally. They always feel a bit dim witted.

The 4C seems to have that much rear traction that...on the several road drives I've had in them...I've never come close to unsticking the rear end of one. I think you'd have to be pretty brutal...and on a track.

What type of LSD does the Abarth use? Clutch pack or Torsen? I did a quick google and downloaded the brochure but all it says is "mechnical".

OP, what is your intended usage?

If competition maybe wait for OS-Giken to produce a differential for this platform - being based on the MX5 I expect there will be one available eventually.

If it's a street car and/or "light competition" then the factory LSD will be fine (clutch or Torsen) and probably preferred.

A Torsen can be annoying at 10/10ths but tame. The clicking/squirming with traction breaking and high G cornering is kind of annoying. By high Gs I mean 1.0~1.4 G.

Clutch packs need maintenance - I'd prefer a Torsen personally.

OS-Giken is awesome but noisy almost everywhere.

I'm pretty sure that the Mazda's LSD is a Torsen. I can't imagine that the Abarth's is different but maybe it is?

GT86/BRZ are Torsen.

I noticed Goodwin Racing put a Mazda limited slip with an ND casing in their car. Go to there site and look at thread on Fiat 124. It is on page 4 of the thread and dated Sept. 14, 2016.

I don't know what's in the Mazdas, but in the Fiat it's not Torsen, it's a cone type, thankfully..
