Spring time has begun, got Q's

[wingsnthangs]

I have a 91 S13 FB, 205/60R15's, currently on stock springs (wheel gap is big enough to punch your fist in it w/o touching anything).

All i'm looking for are lowering springs that would reduce that gap without reducing ride quality (quite honestly, i dont care much for stiff performance if it jeopardizes daily driving).

After reading multiple reviews, i'm debating between Eibach Pro-kits (which seem to be considerably popular and reputable among 240s) or H&R springs to go with my Tokico Blue shocks. Which springs (Eibach, H&R, or others) would you suggest to best fit my needs?

How much I should lower the car: well i'm aiming at roughly 1.3" at the front, but after considering your suggestions, i might decide differently. According to this review, it is not safe to lower an S13 more than 3cm. Is this true?

Open to all input and thanks in advance.
