A Tech Look Under the Scion FR-S!

Mike Kojima pens an awesome technical article about the FR-S' suspension! All your "how will lowering the car effect handling," and "how much static camber," and "is camber adjustable" questions are covered here.

Good article. Definitely some things I'd like to see myself but it did give a few ideas.

I haven't seen this yet. Thanks for posting!

Good to read them confirm that '04-'12 STI front brakes and '08+ rear brakes are a direct bolt-on along with '04 STI front rotors and redrilled '08+ rear rotors. This makes brake swaps quasi-compatible. Next someone needs to find if the newer Subaru hubs bolt on w/ 5x114.3 pattern. Their insight regarding the steering tie rod is interesting, although they're mistaken on the strut having a motion ratio other than 1:1 [disregarding inclination angle or virtually inapplicable absurd force vectors from asinine wheel offsets].

Yeah that is good news indeed. A full STI brake kit upgrade would be what, ~$2500 for everything?

OEM STI 4-pot front calipers/rotors/pads can be gotten for under $800. Rears would be a little less. I'd say $1500 for all four corners, if you buy new parts...find some used ones from some baller that opted for a StopTech BBK and you might score a set up for under a grand.

That is better than I thought. I was just looking online and found some OEM-spec STI rotors (all four), Hawk HPS pads, braided SS lines and brake fluid for $500. Might be a economical way to improve the breaking performance.

That's not a bad price at all

They are SP or Centric brand rotors.

$500 bucks and a weekend in the garage isn't a bad deal imho. While a nice big brake Brembo kit would be nice, probably not worth it until you approach +350-400hp
