Yes, that is correct. Swift designed these springs around the OE bump stops, with proper linear rates and height there is no bottoming issues, including several of our customer who track their M3's at very bumpy tracks.

Most of the reports of bottoming were from progressive and often too much drop Eibach or H&R springs.
