Wouldnt it take ages to notice a difference though.? In savings, would you do it yourself.?
Depends how much I can get the bits for, My mate would put it in for me so the only expenses are the ones from buying the bits.
Thing is, I had another gti once and it had a 5th gear that did 70 at about 2200 rpm,
I figure that the amount of time I spend in 5th gear, I could save moneys, I do drive long distance quite abit.
