Lowest you can go on a 98 TiB

Ive lowered my car and it seems the lowerest you can drop it is 60mm before your sitting on the bumpstops. I thaught the factory sussy would have more travel =(
The Elantras though are better as they allow for a 80mm drop at the front and 85mm drop at the rear before you come anywhere near the bumpstops.

Maybe you could try some shorter bump stops. Couple of the nolathane places sell them shorter but with increased stiffness so you get more travel but when it comes to crunch time it still protects the shock from bottoming out.
