A friend who has a shop finally hooked me up - I used a Wedge bracket from the passenger side of my RSX that he spent about 4 hours modifying to fit the RAV4 platform. I had 2 Recaro Sports previously installed in my RSX about 10 years ago and since the RSX is semi-retired, I decided to install one of the Recaros in my RAV4.
He charged me $150 for the bracket modification. I paid $100 for the bracket 10 years ago.
I'm not quite sure if I like it or not as is; the seat position, especially the rear, seems too low. It makes the RAV4 feel almost like a sports car on winding roads, but makes it a little more difficult for daily in and out, around town driving. Recaro sliders give about an extra much-needed 2" of legroom, much, much needed in the RAV4, and one of the main reasons I wanted this seat installed.
I'm 6' 1", 55 years of age. This is a nice seat, but I would prefer less aggressive thigh bolsters for easier ingress/egress, and a bit higher seating position. I will drive it for a couple of weeks before I go asking for the bracket to be modified again for a higher seating position.
