For the small , tight carpet local track i thought i'd try the position 2 and Orlowski Trencin EOS setup. went lighter in oils (32.5 F+R) added front roll bar and didn't use the rear roll bar (I was traction rolling with the rear fitted.
I'm on Proline Prime MC with SXT3 additive on black CRC carpet. Eventually, i left off the SXT3.
This is an amazing setup (for me) so accurate and fast to change direction.
