I was wondering what differential is best for a street/strip car.
A spool. Many will disagree , but I've done it for years and never had a problem. Regarding the " wet road ' stories that this post is sure to generate , I don't drive my car when it is raining. There are certainly things you need to be aware of , but for a toy car , it is an easy choice.
I had a spool in my 8 3/4 for one summer on the street. 3900#car + manual steering + spool = a b**** going around corners.
