    Hi there,

    Ive just converted my 318 to 328. Ive taken the car out for a spin and its a bit lairy with the diff. I plan on doing a few track days and drift days so a LSD is a better option? Ive found one out of a 328, what else would I need to do the swap?

    Not sure about the 318 prop and drive shafts, but if you're using the 328 prop and drives shafts you want either an M3 3.0 lsd or a 325 lsd, both have a 3.15 ratio (quicker acceleration at the cost of top speed) The standard 328 diff is 2.93.

    The flanges for the prop shaft differ so you'll need to put the flange from a 328 diff onto the new diff.

    Im using 328 prop from gearbox, then 318 prop to 318 diff. So what diff do I need? I got the 328 prop, diff and driveshafts, but the 328 diff is not LSD. However I may know for a 328 LSB
