Not sure yet if to let it go, but I've got an jdm(wrx), cross sports, '07, EJ205, 4eat (sport), 50k/ish, first UK owner. Not cheap.
If you're interested let me know.
What Judd said.
2007 Cross Sport JDM with 4EAT transmission, transmission oil "refreshed " as through regular procedure you can only drain about 4 ltr. My concern would be that if contaminated with 75w80 (100% sure it's diff oil) a full drain would be necessary.
I did it myself with this:
Flex Z too, but I found the problem. The ARB(22mm) on the softest setting (outside hole) had not enough travel room and was hitting one of the suspension components. Replace it with 17mm ARB (the original) and Bob's ur uncle.
Hope it's helpful.
You are not the only one. I've got the adjustable tein and running on almost the softest setting. It looks is not the dampers, is the springs. I've also had the rear 22 mm ARB and replaced back with the original 17 mm. ( the 22 mm is for sale)
Looking for ideas too.
