What are the advantages if any on getting the rears?

Is it ok to just get the fronts?

I have bmr lowerings springs right now and they are killing my 60ft time.
should i get rid of them all the way around or just get rid of them up front

thanks

The rears can help, you can just add them later.

IMO the fronts are 80% of the value.
