Yes it would seem there's quite a few Kits just for the D-series engines. The exedy catalog seemed rather promising and straight to the point, and using the information they give me, I'm doing my searches. What differences did you encounter?
The arch gap does look bigger now as these are 15 inch wheels and fill the arch less than my 16inch Rotas. At the same time the car is lower than before because of smaller wheels. I really want to lower it further but it already scrapes on the smallest of speedbumps I don't know how I would be able to drive around if I lower further lol
