Hey hey don't need to make me sound like dumbarse!! @superben Bit un called for lol just asking the question. I heard that the s2 are more efficient, in the way i asked was to see if there are ways to upgrade the s1 to be more efficient, so obviously you cant. Our turbo diesel nivara gets more kms with the caravan on the back of it, so yeah I think it was a reasonable question, as most cars have chips or re mapping in place to get more power and better efficiency. All good anyways.
Its going back to Race Pace soon and there getting new coil overs designed specially for Stageas which apparently will sh$t all over the BC and SLIDE ones, so ill get them on the car and ill see if its possible for any sort of re mapping or get a s2 head on it or something.
