How low should I go ?

Ola Amigo's

I'm after a bit of help again!, I have lowered spring and shocks on my mk1 Karmann cab (89) but the back seems to be alot lower than the front (this is how they were when I bought it. I'm going to buy a set of springs but am unsure how low to go. any advice, or pictures would seriously aid my decision.    :dontknow:

I'm running 15" ATS cups if this makes any difference

Thanks again
