    Optima Battery HELP?

    Anyone want to shine some light on which Optima battery to use for the e30? I got some response that its should be something like group 34, but is there anything else differentiating them?

    Also the stock battery has 65 amp or something of that sort, the optima is lower, does this matter?

    Optima site also doesnt show you which on to buy.

    Concrete answers please. Thanks.

      Optima Red Top is the right battery. You will need a custom battery tray and hold down.
