mini spool off ebay $90 http://shop.ebay.com.au/?_from=R40&_trksid=m38&_nkw=mini+spool. the question is how much do you want to spend. second hand lsd diff $250 but if its a sh!t centre you may aswell have a single spinner. you should also look into changing your gear ratio stock 3.08, vl diff is 3.45 r31 3.89,
I've got a 3.08 LSD already and want to go 3.9 or even 4.11 - what is the best/cheapest way of doing this ? Can I just swap centres or do they have to be professionally installed to set up the lash ?
