Does anybody have any good ideas with regards to making our S3/A3's lighter? And getting the power to weight ratio up a little. Some ideas I have:- Remove sound proofing. - Don't really want to do this. Any1 any ideas how much weight this will save if it is done? Purchase Titanium exaust. - Does anyone know if these exist for the S3. They are 1/4 the weight of a normal exaust apparently. Remove Spare wheel and jack. - Just an idea /ubbthreads/images/graemlins/laugh.gif Light weight alloys. (27lb approx? RS4 reps at the mo) Purchase lighter Battery. - You can purchase batteries that are 65% lighter but they cost a packet. (about £200-£250) And cant imagine them saving much weight either. There are other options such as removing motors from the Seats etc etc etc, But I don't want to do anything like that! If you could shed 100Kg's for the car, do you think it would make much difference?
