Looking to replace the rear disc rotors and pads on my 1997 Legnum ST-R.

Does anyone know what US-imported cars shared the same brakes?
 
If I was to guess, an Eclipse of the same era would be as the rear suspension is all near identical.

Most parts places will have a lookup tool using dimensions, just measure the rotor.
 
These 2 images should help as far as sizes are concerned. Happy to send you the fronts if required.

You linked the vr4 op has a st-r
I'd love a front brake reference picture, too. However, it seems, according to jdmftwyo, that the ST-R has different brakes than the one you posted (VR4 brakes)?

This is based off the assumption that the VR4 specs are similar to or same as the ST-R specs.

With the specs that you provided, looks like in the US, the 1995-2004 Eclipse, 1999 - 2003 Galant, 2005-2006 Outlander 2.4L & 2004-2006 Lancer Ralliart 2.4L share the same rear discs:

EDIT:
As @98leggy pointed out:
"stock part number crosses to the 2nd gen eclipse gsx and 300gt\g"
>> https://www.mitsubishipartswarehouse.com/oem-parts/mitsubishi-disc-rear-brake-rotor-mb928716

I definitely trust mitsubishipartswarehouse.com over allrotors.com, but I'll update this thread after buying a pair of rotors using the 2nd gen eclipse specs.

If it hasn't been done already, I would like to start a 'Compatible Parts' list for Legnum/Galant owners to show what other Mitsu models, both import and US, share compatible parts.

I ended up getting the rear discs from a 1997 Mitsubishi Eclipse 4G63T AWD on rockauto.com (very reputable parts warehouse) and they fit perfectly, no issues.

So, it looks like @mezje was right. Thank you.
I have a list of parts for us US folks.

 
If PFL caliper and rotors are any kind of an upgrade for the ST-R, I’ve got a good set coming off for my brembo swap.
