im going to buy two sparco sprints as well as two of sparco's four point driver harnesses. my question is what all do i need to buy (aside from the seats and harnesses) to make this setup work (brackets, sliders etc.) i need to know everything i need to buy so i can calculate how much this is all going to cost...i already removed my back seats to be able to bolt the harnesses into...but can somebody show me a pic or diagram as to where they bolt onto? thanks.

 

I think you might want to consider Sparco Speeds if this is a daily driver, they feel better than Sprints supposedly and have protection against wear.

The way to mount your harness is to all the stock seatbelt locations. The only place you might have a problem is the right side of the lap belt, where you might have to drill a hole through the car to get it to mount properly (or just run it to the right rear lower bolt that holds the slider, but its unsafe)

 

you also need seat brackets, yes
