What ratio diff?

[monty1991]

hi. After many years I finally have my car on the road

but my diff is far to low of ratio I think. speedo is miles off

the diff is a 2way kaaz and complete overkill for what I need. so gonna replace it. for a oem stock lsd

but what ratio should I look out for?

spec s with det conversion with 5 speed gearbox.

any help would be appreciated guys

pic of the car finished for my wedding
