Anth's Iroc

I have an 87 iroc i want to take to the the track and drag it.But here my dilemma.I want to lower it also,but will lowering my car take away from my time att the track i know lowering springs are harder than normal ones.I was also thinking about switching to 6cylinder springs up front and 3 way summit shocks out back.I know the 6 cyl springs will lower it a bit also.Any advise would be greatly apprieciated cause i want ot get started this week on it.
Thanks
Anth
