Hi

I am having a problem about my suspension setup

My Problems:
1) My car rear end is about 1"-2" lower than Front End, so it looks really stupid.
2) I couldnt lower the front end much lower, because Fr tyres hit inner guard when I turn during my car bounce.

This is my set-up:
195/55/R15 on 15"x7" +10 offset wheel
Tokico Hts
TRD Springs F 6kg R 4.5kg
No coil-over

What I did was:
1) Put all in, but i didnt use coil-over strut casing, because I didnt want to abandon my Front 6Kg springs.
2) Caster & Camber are adjusted for a fine clearance, but the front still hit


Now, what should i do?
Get coil-over kits & lower the front end to match the rear end?
Will I need to get a new coil spring for it??

Any suggestion guys?
