Basic tech info: spring rates, rear suspension, motion ratios, and you.

If you think this is amazing from scratch just keep it like this.

Or if you want a little drop maybe yes RCE yellow can do a good job without sacrificing too much the handling.

Correct me if am wrong but I think RCE yellow make the car feel more neutral vs OEM.

This is my feeling also on Mach V springs.

Thanks for the thread!

I want to lower my 2015 but it would suck to change negatively in anyway how it handles...because it's amazing!

Same springs as before, shocks are slightly different. Not a very large change.

Is this the same case with the 2015 BRZ?

[Racecomp Engineering]

Yes.

So if I just want to lower my car around an inch, as I love the driving dynamics, would the RS-R S/Down do me well? Or would I also need to upgrade other areas of the suspension as well like sways, LCAs, ert?

Only a good set of springs and an good alignment will be fine to start.

No need LCA for around one inch, I don't have LCA and am dropper 1" 3/8...

Of course adjustable LCA are better, but this is to fine tune your alignment.

You can run only lowers springs without any problems don't worry...and if you want, in the near future you have always the time to upstage others suspensions depend on what you will need concerning the handling of this car.

^ Cool thanks. I've had coilovers before, but not sure if I want/need them if I really have no current plans on dropping below 1 1/2".

Some of these links (most maybe?) have already been posted on here but they are all over the place..

List:
Far North Racing - Shock Buyers Guide


Far North Racing has other good info on their site also.

So which vendors here will provide dyno plots for individual shocks...?

Also thanks for the list, some great reading!

Vendors? Probably few. Some manufacturers will.

I love our 2013 GTS86 auto but at 70+ years of age the wife in particular hates the hard ride. Can anyone advise on modification to make it like (for instance) a Golf GTI which seems about the right amount of suppleness for our taste please.
I am thinking trying different springs first then dampers but have no idea about rates.

A set of new or lightly used 2017 or 2018 BRZ standard shocks would be my recommendation.

Bilstein B6 will ride well too, but a little more "sport" in comparison.

If ride quality is your main goal, I would stick with OEM springs.

BUT the new version of the Ohlins coilovers would also work well, at quite a bit more cost.

I'm also in the 70+ age range. Believe it or not, sticking with the non-PP wheels, tires, suspension AND using a good gel pillow for my wife (who weighs less than 100 lbs), works best. It turns out that the thin padding on the seats transfers the jarring and when that is subdued, the ride seems a lot smoother. I'm thinking about having extra padding put in the bottom of the seat. We actually have a similar problem in our SUV, believe it or not, and she uses the cushion there as well.

Thanks & a simple enough solution to try. She would like to sit higher too.
