I have the damps and love them. Bilstein requires (for them to work as they should) dropping them the minimum Cannga notes in his post. And yes plan on replacing the lower front lip ever year at least and for it to get beat up a bit. I have a driveway problem as well and the roads in San Diego are full of deep dips so you get scrapping all the time. No worries, it just shows you actually drive the car! Once you get the damps installed you will find the lowering a minor and acceptable inconvenience. Now if you lower it more than the minimum - well, good luck. The angle system (slowly - crawling) works fairly well and you'll find yourself finding your preferred places to enter and exit places. You'll get used to the scraping sound - but if you find it popping out in the front or side just drop by your dealer or tuner and they can easily pop it back in for you.
You will be very happy with the damps! Get ready for a completely different driving experience.

Guys I rely appreciate your impute, I think I well measure exactly how much I can lower my car and steel drive in to my garage and take it from there.
Cannga it took me some time to finish your endless topic but it was well worth it. The suspension comparison between TT, GT2 and Bilstein Damptronick it’s very educational
