For a good front spring rate look into some coilovers in he 150# range. Add some adj struts and shocks(strange engineering get my vote) and some Team z rear springs teamed with some better read control arms. I've got some new in the box TeamZ upper and lower control arms for sale if interested pm me.
PS-getting these cars(assuming manual trans) to "hook" with street tires on the street isn't going to happen.
