TRD Suspension Package and BRZ Performance Package

[MrClean614]

Hello,

Did a search didn’t find an answer.

Wanted to find out what the similarities and differences are with the TRD parts in this package compared to the parts contained in the optional performance package?

Thanks

Background:
Buying a BRZ with PP and planned on lowering it with Eibach/TRD springs. Then I saw this overall TRD package and wondered if it was worth getting it (i.e. adding bushings, swaybars larger diameter?)

Can an admin move this thread to the suspension forum?
Thanks

On my performance pack brz I put the Tein street basis z coilovers. Can be had for under $500 and they ride better than the PP Sachs tuned shocks. There's already very little suspension travel on this platform, so a lowering springs makes it even worse. I know some have blown out their shocks with lowering springs too.

Appreciate you sharing, as I’m new to the FT86s.

Any idea if the PP swaybars are the same size as the TRD pkg swaybars?

I have the Eibach Pro-Kit springs on my BRZ, they are similar to the TRD. I think they fit great.

Thanks for chiming in, weederr.

By chance have you seen and driven both?

Does the Eibach Pro-Kit setup sit lower as the advertised drops indicate?

If you have driven both, any noticeable differences?
(I’d imagine not but still thought why not ask)

BTW, just looked at your build thread; wow- you’re car looks and sounds friiggin’ amazing!

Oh and nice reference to the RUF legend (yellowbird)

Thanks!! I'm glad you got the RUF reference.

I have owned both sets. On my previous FR-S, I had the TRD springs (although it was with the '13 shocks). I liked both. Not too harsh, imo, and also the right amount of drop without having to go to coilovers. They both sat around an inch. I haven't noticed much of a difference but never measured either.
Personally, I think the Sachs with the Eibachs are damn near perfect. Though if I were to suggest an alternative, I'd steer you towards the RCE yellows.

That’s just the kind of real world feedback I was looking for, thanks!

I was thinking the same (Eibach Prokit springs + Sachs would work well together).

My initial focus is going to be street/backroads driving with an occasional track or auto-x event.

Know where I can find out what the PP swaybars sizes are?

I liked the idea of that TRD suspension package (decent value) but didn’t know if the swaybars are the same sizes as what comes with the BRZ PP.

Thanks again weederr.

No problem!

I don't know the size of the sway bars but I'm sure it can be found. I haven't bothered to change them since I daily my car and feel no need for larger bars.

[MrClean614]

Here’s the TRD specs for the sway bars...

Anti Sway Bars (PN# PTR11-18130)

20.6mm 4130 solid front sway bar
15.8mm 4130 solid rear sway bar

Anyone know the sway bar specs for the Subaru performance package?

So far unable to find the measurements for comparison.

Thanks!

I'm not really impressed wih the Sachs dampers, I acknowledge that compromises are made for the average buyer, but if you are looking at an OEM performance upgrade it needs to be better than the suspension in the PP.

@MrClean614

Front sway bar is 18mm
Rear sway bar is 15mm (+'17 model) 14mm (pre-'17 model)

Thanks nikitopo!

Taking my first roundabouts tonight, noticed the BRZ has some understeer dialed in from the factory to be safer but I’d like things to be more nuetral.

I remember seeing a YouTube review of the ‘13 FRS and BRZ which indicated the FRS was setup for more tail happiness when compared to the BRZ. That made me wonder if that TRD suspension setup would make the car more neutral?

Found it:

EverydayDriver video from 5:30 on covers this.

Appreciate you chiming in to share this - helps align expectations. I’m going to attempt to make the Sachs dampeners work with some Eibach Pro Kit springs for now. Depending on how this goes and how much I get into tracking the car, probably consider Ohlins R&T coil overs.
