ABT,
I hated the guards sitting so high over the rims
Are you in Sydney? Most places here do not have springs lower then 1.5" for IS200s. As I originally wanted a 2-2.5" lowering, the kit offered by Eibach here only lowers the car about 1", so I had to look for other brands. Similar situation with Pedders.
I recently lowered my IS200 with K-Mac springs. They custom make each spring to your required height. I originally had them make new springs which lowered the car 2" front and 2.5" rear. Looked very nice with tyres sitting a touch inside the guards.
However, after a week, I had to take it back to raise the height slightly as I had trouble with the body kit scraping driveways and humps :(
Now, it's about 1.25" to 1.5" lower than standard.
Cost about $610 fitted with 4 wheel alignment.
It all depends on whether you can handle the bumps and scrapes.....then again, if you don't have a body kit, then it's no problem
