How good is the Haynes IRS?

Don't forget you can also use the granada diffs but you will need to extend the top left mount outward 17mm ( looking from the back of the diff) this will give you a few more options! Also I find the Granada LSD diffs are stronger and cost less.

Thanks guys, i'm not too fussy about diff ratios, but it must be LSD. I started with the original 3.09 in the atlas but changed last year to a 3.77 when i fitted a bigger turbo to compensate for the increase in lag. I have over 350 ftlbs and climbing so i dont notice too much difference.

A 3.6 or a 3.9 would be fine.

A dedion wont really fit as the centre of the tube has to sit behind the diff and my fuel tank is fairly close to the live axle as it is.
I guess i will have to look at getting a book. The reason i looked at the haynes was because the parts were easily accessible on ebay.

Is the Stylus like the Fury ie same track width? If so you are into chopping down the drive shafts as the Roadster uses them as per the sierra.

thanks for that, i did wonder if the stock shafts would be wider, i think i can get the shafts shortened, or new ones made but its an expense i could do with out. I was wondering whether an MX5 diff and shafts would be the right size. Of course that means using MX5 based uprights. I will have to look up some measurements.
