Well i dont have it installed yet but im going to do it as soon a finish some upgrades first... well starting for the fluid is a lot better than the oem that our cars have from factory... the line... well i have a friend that installed on his car and he tell me that he dont feel a lot of difference with the line but the thing is that our cars early or later are going to have CSC problems ( I hope that not happen to me but we never know )... and i think that I read here in the forum that with the clutch line some of the members can resolve the problem when the clutch pedal goes to the floor.... Anyway is a simple mod and not pricey
and if you have plans to change the clutch fluid why not do that mod too
For more info hit the link that i post... they explain the reason for change them or just do a little search here on the forum
