I have an Autopower roll bar and Sparco seat - I also own a Schroth Quickfit harness but was hoping to switch to a different bar mounted harness. I suppose there isn't really any advantage to that though.
No, there really isn't. Plus, in order to run a different harness (other than the Schroth), you need to get the plugs for the seat belts, with the Schroth, no need for those. Tbh, if I had to do it over, I would have got the Schroth harness'. As of now, I'm running a Autopower harness on the driver's side, and a Sparco on the passenger side (when the seat is actually installed). The reason I say I wish I would have went with the Schroth is because I'm slowly turning this car back into more of a street car, and the roll bar is coming out, which means now I'm going to have to pay for the Schroth belts anyways. Lol
