2 will feel like you have to apply more pressure for sure. Around town this may be a bit of an issue, until you get used to it anyhow.
Don't forget you won't have a brake booster to assist.
An advantage is you can set up a brake balance bar/bias system on your brake pedal so you can adjust F/R bias accordingly.
All the above good for racing.
If it's room your after due to a conversion, perhaps better to relocate the booster up front somehwere and just have the cylinder on the firewall.
