Bump travel: Bilstein B6 vs Koni Sport - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

macuser27 · 03-08-2021, 05:02 PM

I bought my car used with RCE Yellow springs paired with Koni Sport dampers all around and have a couple questions.

Will switching to Bilstein B6 increase bump travel?

Do the bump stops get transferred over and reused?

IIRC on one end of B6 had builtin internal bumpstops, but for other end one reuses stock bumpstops.

The difference between the two is rather minimal.
Have a search, there was something posted by RCE Andrew about this.

In front or rear?

I'll have pictures and some measurements of Bilstein B6 compared to stock in the next few weeks. I think they're fairly close (and Koni should be as well).

I tried searching and keep getting off track as there are so many interesting threads/posts about this new-to-me platform. Just got into a 2013 BRZ last month after 10-15 years in SN95 Mustangs.

Yeah that's us!

And like churchx said, you reuse OEM rear bumpstops, but not the fronts. Bilstein have internal front bumpstops. Reuse front and rear dustboots.

EDIT: i'll update this thread with pictures eventually:
