Me too.. The strut brace has turn backle adjustment. lol

Some of those "monster" braces look a little suspect, like they don't actually reinforce anything, or they reinforce something that already has existing chassis reinforcement... Like the bar behind the rear diff and rear bumper...

It's not really adjustable. the link is there for flexibility. YMMV

"Flexible Tower Bar
This totally new concept for a strut tower bar is designed from an aluminum tower bar divided into two segments and joined by a link ball. It disrupts unwanted force applied vertically, such as through gaps in the road surface, by flexibly bridging such force to the left and right sides, and holds strongly against lateral forces. The result is an improvement in riding comfort as well as handling throughout the entire range of steering. "

I remember when STi introduced the "Yamaha" strut tower bar a few years back with the flex section in it. I had no idea how a "flexible" strut tower bar would be beneficial, however I figure if the engineers at STi say it is, then I believe them. I am under the impression that on a street car you do want some chassis flex, however you want to have control over the flex, and that is what these bars do. Either way I love them

For reference.

Thanks,
Rick

It will be cool to see how the two in house tuners do things differently.

Calum · 08-21-2012, 05:22 PM

I'd love to know the spring rates.

thermobox · 08-21-2012, 05:55 PM

I just think that it's pretty wild that Subaru and Toyota are holding firm at a 15mm drop.
These springs drop 15mm.
The TRD coilover kit comes shipped at a preset suggested drop of 15mm.

I would assume that when STi does their coilover kit it will be a 15mm drop.

I'm so torn at this point. Racecomp Yellows (20mm), STi Pinks (15mm) Eibach Pro-Kit (25.4mm) or just go for coilovers? Meh.

sti pinks are excellent.

Based on?? Do you have them fitted to your car. I don't think anyone as tried them to say that yet...
I have some sprngs waiting, which I foresee to be excellent, but they aren't yet fitted and I don't know anyone with the same product fitted to be able to say "they are excellent"

Surok · 08-28-2012, 01:47 AM

Just put a set into my fathers 06 sti

judging by how they go, i can reliably say that the pink springs for the BRZ will be also.. quite ezxcellent upgrade from stock

....

I would *guess* based on other Subaru stuff that something in the camber curve (or possibly toe curve) goes wonky when static ride height is set lower then 15mm from stock. You'll know for sure when companies start releasing correction kits, offset bushings, modified ball joints, etc....
