Suspension kits come in a variety of formats where some have OEM style springs and others have straight race springs. If you choose to change to different springs you might need to change your spring perches to match.
The e46 M3 Vorshlag camber plates have 4 perch options:
- 2.5" (65mm)
- Spring perches are sold with the perch, thrust bearing, and top pin adapters (aka adapter spools).
- You will need to note at checkout or Contact US with which dampers you have so that the correct top pin adapter spools can be included.
- Perches are priced as pairs.
