suspension question

[da89soup]

Ok, question!!! But first some history!!! I have been a huge supra fan my whole life. Parted with my first mk2 right after collage for a newer more reliable car. But I never lost sight of the supra. A couple years age I finally convinced my wife that I needed a project car. I bought a hailed out, wrecked, non running 89 NA Targa with 130k. It has taken me two years to put it back together. Ebay has been my friend. All the work I have done myself. All body work, paint, interior, engine work ect. I am no mechanic I am a advertising executive. So proof positive when you are devoted and want something enough anything is possible. The car is in storage for winter, all that I need to be 100% finished is stock front air dam/lip, mine is missing. Car apperars and is 100 percent stock. Now that I have put it back together and got to drive it this last summer I am ready for mods (7mgte). I want to first start with wheels/tires and suspension. I dont like the looks of huge wheels skinny tires. I am planning on a aftermarket 17 chrome rim that looks close to the original stock star rim from 91/92. I am planning on 245/45 front and 275/40 rear. I want to lower the car but I dont want to slam it. I want a clean look. Anyone have any sugestions for springs ect.
Thanks
