I think I am leaning towards the pro kit. They don't drop the car as much as the h&r and leave a very nice look. So there is less chance of bottoming out. I like the look of the h&r more, but I am hearing to often about hitting stuff and I don't want to change my driving style because of that.
front spoiler sits a bit low and ends up getting scraped up. even on my stock height 03, i have a few scratches. im also considering removing that front spoiler. from the looks of that yellow 03, i wouldnt it say it looks bad either.
No offence i think it looks like crap. My 01GT had the 03 bumper on it and they forgot that lip...until I ordered it I was ashamed to drive it. Looks unfinished and you can see the edge where it fits in.
I just don't get the bottoming out thing... If you're gonna lower it, LOWER IT! What's the point for a .5" drop? I have no issues with scraping at all. Unless you are driving like a mad man over logs and stumps in the road, I think you will be fine, I love the look/stance, and the handling the HR's give you. I don't run the twisties, but for track/daily driver, they rule! Just my opinion though. I do have the urethan isolators that give .5" higher than just stock isolators.
