Sorry if this has been answered already, but I couldn't find it using the search function.

I'd like to lower my car slightly...1" front, 1.5" rear approx - like the Eibachs....without adversely affecting the load bearing as I do often have to carry some weight in the back. A slightly stiffer ride isn't a problem, maybe even preferred.
Will SRT springs lower my N/A coupe without cutting them, and if so, how much?
Thanks!
