I realized a squeak developed in my Driver's seat and its getting really annoying so I am thinking about upgrading to some nice race seats with the 5 pt. harness. I looked around and Sparco is wayyyyy to expensive. I was looking for a budget of about $450 with 2 seats and the harness. I know how APC makes a lot of rice garbage but these seats don't look half bad. Is the race seat install on an 02 rex hard or does it require special brackets or professional installation? Thanks!
