The Ecelica stores sells all three versions of the Blitz front bumper. The US Spec Fiberglass version, the US Spec Urethane version, and the JDM Fiberglass version.

I have the Blitz front bumper US spec fiberglass with veilside rides and rear. The bumper is probably 7 inches off the ground, which is quite high. I haven't scratched anything yet and the roads in NJ are pretty shitty. The bumper is not as low as you may think it is. If you drop the car, you have to consider a reasonable drop so you do not scratch the front. If you want a close up pic of the front of mine I can take it because I DO NOT have a drop. My celica is stock height with stock wheels/t res.
