I have Eibacs with aero kit front on the third world country roads of mass with hardly an issue. Hardly being the key. Some driveway ramps are tough. Ride quality is the same as stock.

I've had my Eibach Pro Kit installed for about 3 weeks now. I've never bottomed out. That sounds pretty extreme and leaves me wondering if you mean something other than what most of us think of as bottoming out.

Scraping something on the undercarriage is not bottoming out, whether it is the lip on your front spoiler or something in the middle over a speedbump, that is is just scraping.

Bottoming out is when your shocks completely blow through their travel and you hit the bump stops on the shocks. That is extremely jarring and the only time I've ever felt that in normal driving is when I've purposely tried to get air over a bump and landed hard (never tried to do something like that in a Porsche).

Bottoming out at speed on the freeway seems almost impossible unless something is seriously wrong with your car. Your shocks don't have much to do with bottoming out (imho). It is the job of your springs to keep your car suspended, and the Eibach springs are not an aggressive drop at all. Not to mention the fact that they are progressively wound and become even harder the more you compress them.

If you are truly bottoming out at speed on the freeway it sounds to me like you either got the wrong set of springs or a defective set for your car.

Thanks for the post Derek. Can't wait to pick my car up tomorrow.

 

I have Techart(made by Eibachs) and zero issues, the ride is as good as stock while the looks is much better.

 

Had Eibachs, 20's and a GT3 cup spoiler. Never bottomed out on uneven roads. Did a run once on uneven pavement and a Z06 in front of me bottomed out several times but I didn't. Ride quality was harsher than stock but not terribly so. Having said that, I sold the 997 for a CLK 63 BS and am loving the "softer" suspension.

 

Uploading some before and after pics. Overall drop is 1". Put about 50 miles on it last night. Seems to ride better than stock, much higher speed through corners, no bottoming out even at triple digit speeds.
