Which rear bump stop to use with lowered suspension?

Does anyone know which rear pump stops to use with Koni yellows and Swift Spec R springs? I installed the bump stops that are used on the sport suspension, but it seems there still isn't much free travel.

I've these 33 53 67 88 9 05 with BMWP springs.

From what I've gathered, the Swift Spec R are a little lower so may not be perfect for you.

Factory should be fine.

Have you visually observed the amount of compression travel? Factory bump stop is a secondary spring and progressive. You can trim to gain more travel.
