FYI I got that information from the parts guy at Rocket Racing in Squamish. Very nice and informative.

Hi all,

Maybe it's time to update this somewhat. Does anyone know of a list of CLSD's R160 or R180 that are available to us today and exactly what cars they came out of? I just spent 2 hours on the forums and didn't find a conclusive answer at all. Maybe just in the wrong place.

The question keeps coming up, and this must be the right place to put the answer.

Thanks everyone.


Did the guy at Rocket note which were CLSD, opposed to the VSLD?

I got this from Dave Patten of FutoFab fame when inquiring about his axles for the Subi diffs and which diffs there for.

These are strictly STI models only, 2 ratios, 3.90 (04-05) and 3.545 (06-15) and come with either a CLSD (04-07) or Torsen LSD (08-15).

None of the RS or WRX diffs listed above are CLSD. '98 and '99 RSs the LSD was optional, but standard on '00 and '01 cars.
