Options to convert Open to LSD diff
Hi all.
I have a LHD MNR with a 7" 3.62 open diff, push in halfshafts, originally fitted with drums.
During the last trackday, while alone (on the left side of the car  ), I was having grip problems on all slow corners to the right side:
During the exit, I was losing quite a lot of time managing the throttle, because if I floored it, I could hear the wheel spinning, and there was no
further accelaration.
With a passenger, I could floor it and I was able to put down the power.
Also, I was hitting the rev limiter for the last few hundred meters of Estoril GP straight.
In order do overcome this 2 problems, I was thinking about converting to LSD and lowering the ratio.
I recon that I can't change the internals to Sierra LSD, and I don't want to change diff / halshafts / ...
Is there any other feasable option (not to expensive) like AP Suretrac or Quaife?
What are your opinions?
Thanks in advance,
Joao

Cheapest option is the back end out of a 2wd Cosworth or DOHC Sierra.
Aftermarket LSD's cost a fortune!

The Cheapest option is to get a lsd diff about £150/£200
and buy two inner lobro joints then use ur push in driveshafts.. BUT and it's a big BUT that's if ur push in drivehshafts have the right
number of splines to match up with the inner lobro
and sadly the only way of knowing is to cut open the inner joint of the push in.
if it's a match then you can keep shafts/hubs the same ie push in on the outta joint and bolt on for the inner joint
i tried this with an old pair of push in shafts and they were the wrong type ) can't remember the number of splines)
so i ended up chaging the whole rear end shafts/hubs and also had to get mnr to make me new rear uprights!
