SATXSC400

I need some input guys I'm thinking about putting on some wheels and wanna make sure they will fit. I'm thinking about putting 20" wheels on my 98 SC400. Specs would be 20x8.5 +25 F and 20x10 +25 R with 245/35zr/20 front and 275/30zr/20 rear for tires. Car is currently stock height, but I may lower her 1" with Eibach springs. Anyone happen to know if they will fit? I would appreciate any input. Thanks..!!
