It depends on the seat and your leg length.
The Sabelt Titan Max XL racing seats look a lot thinner than the Cobalt seats, so that helps, but the angle of the back might not be the same as the firewall angle. Maybe Nate can grab a tape measure, and measure from the seat back (low) to the pedals... You can measure your car, and see what leg length you need.
I bought the extended frame, and have more leg room than any vehicle I have ever drove (100+ vehicles), and that is with the thick Cobalt seats... so those thin racing seats in a stock frame will probably fit you.... unless you are all legs, and have difficulties in most stock vehicles.
