mondial ride height

I am wondering about lowering my 88 mondial. Previous owner fitted 17" MOMO wheels, lower profile tires. Same OD as original. (Yes, I have originals.)

I am aware that starting with the mondial t, cars were fitted with adjustable shock/spring assemblies. I am also aware of a few shock/spring assemblies available, but was wondering if anyone was familiar with euro spec cars. I'm assuming ride height was higher for US cars due to regulations here (maybe not true), and wondered if the easiest way to low car a bit was to use euro springs and then adopt euro alignment specs if necessary.

Thanks in advance.
