i've noticed a rudding noise when i push the clutch pedal to the floor....
and that the pedal has gotten slightly harder since its gotten warmer....
its a stage 3 cm clutch...
would that inline four steel braided clutch line improve the feel of the clutch ?

 

well being that you had that kinda problem maybe its time for you to bleed the slave cylinder for the clutch pedal. Your probably got air in the lines it should be right next to what kinda car you have? it should be next to the brake fluid but dont quote me on that . Id check my fluids if i were you before i do anything and reblead the clutch slave cylinder bro.
