275/45/17 with coilovers

does anyone know if 275/45/17 will work with coilover springs, I have added a tubular k member to my 96 Gt and for some reason it slammed the car down onto the front tires. So Im thinking coilovers might fixed that, I removed the inner fender and rolled the fenders but it just looks bad and rides really rough. Heres a parts list of the front end parts:

17x9 275/45/17
H&R supersport springs with isolators
MM K member
MM CC plates
KYB Struts
Steeda Balljoints w/o spring spacers
Stock control arms

if anyone thinks they may know a fix to this, let me know, I am thinking coilovers may fix it , but im thinking they might rub on the 275's It is Extremely low in the front

Thanks
