Then, you have my permission to get a light weight battery.
saving close to 40 lbs which would be the same as a race seat savings and the total combination of both cf hood and trunk.. in terms of 50/50 the front on xi is I believe 53% of weight and 47% in rear.. the xi sucks weight wise it was impossible to find a aw/cr 335i fully loaded with under 40k miles for the price I wanted and never been modified or in an accident and properly taken care of.. I am not looking to go all out reducing weight and being a race car im happy with a comfortable fast car I am just looking ta the savings of $250 from oem battery and the 40lbs.. take the savings where I can and since a battery is needed why not.. I am still undecided but I will keep you guys up to date.. as far as I am aware some people have run these and they have lasted for 4-5 years never a problem and never having to be coded with the car!
