IS200 diff ratios, anyone aware?

[GRAMS]

Hi guys!

Spent couple of evenings googling but couldnt find any decent info about the ukspec IS200 diff ratios. If anyone aware of them please share some info. Currently have an auto open/welded diff with an annoying gear ratio and looking for any options to lower the revs after v8 manual conversion.

Appreciate in advance!

IS200 manual 43:11 (3.900)

IS200 auto 41:10 (4.100)

IS300 43:12 (3.583)

Thanks mate! To be more specific I have found IS200 manuals tend to have 3 different types of diffs - M59, M85 and M98. Do you know if they are all the same ratio?

I'm only aware of two diffs for UK vehicles, standard and LSD - they both are 43:11.

If you get one from an imported Toyota Altezza AS200 then that will likely have a 43:10 ratio (4.3). Imported Altezza RS200s can have either 43:10 or 41:10 ratios with LSD or 43:10 standard.
