1. If you track the car and need/want the camber, yes.
2. Yes.

Revised Question 2 because that's what I'm thinking of right now.

Recently put on MPSSs and now when I'm approaching the new found limits I find the car bouncy/floating mid corner when going over even mildly uneven pavement. Is it possible to keep it predictable and steady going over bumps while the bump stops are well compressed? Without either spending a shit ton of money, or turning the limit into a knife edge that I wont feel comfortable with either?

Set up is stock unless otherwise stated:
RCE Yellows
Whiteline: diff inserts, subframe inserts (I doubt these would have much to do with it, but it's possible, camber bolts, and front control arm bushings.
And of course, the 215-45-17 pilot super sports.

I think u can try to keep off the bump stops by adding roll stiffness via anti sway bar or stiffer spring rates, but you might have other problems to worry about if u go that route. You probably have to source out different bump stops or live with it otherwise.

Um. When staying to the adjustment recommendations on the spl parts camber arms, the most negative I could get the camber (on a stock car) is positive 44 minutes left, and positive 4 minutes right. Can't get the toe anywhere close to acceptable. Is it safe to just thread the thing out beyond their nominal limits?

@Racecomp Engineering Andy, any solution/suggestion for this?

When I had the Swift sport spring and cut bumpstops I had similar issues riding on 245/45/17 Goodyear F1's. I just figured that it's something I'd have to learn to drive around until I upgrade. You really cant ask for perfection with a set of lowering springs on factory dampers. Didnt really think it was that big of a deal, the bounciness, to be honest. I still like it much better than all stock FR-S suspension.

Not sure what 44 minutes and 4 minutes means but maybe some of the vendors like @CSG and @Corner3garage that sell these things can help you.

There are 60 minutes in 1 degree.

You can still get some toe with the OEM toe links. The camber arms have none or minimal toe adj. SPL does sell toe links (in conjunction with their lockout kit). How much toe are you looking at?

Better shocks will help.

Any time line on the revalved bilsteins?

Wow did not expect that from these spl arms with only a fraction of a degree of adjustment toward negative. Extending them beyond recommended length is going cause problems. he should really call spl up or consider a different brand.

Heh... I thought you were trying to avoid spending that kind of money.

Unfortunately it doesn't look like we'll be able to do custom Bilsteins for this platform.

Might have something else up our sleeves, but too early for a timeline.

So still nothing on the TRD springs as to whether they positively or negatively affect the handling of the FRS?

Really just looking to keep the cars ride quality and handling as close to stock as possible.

~$1000 for good dampers I'm fine with I've been discretely encouraging Andy and Myles, for close to two years now, to make a custom valved damper set.

It's things like the Ohlins coilover kit at ~$3100 plus paying someone to corner balance the car afterward that I'm looking to avoid.
