They say it's all new or revised, but I wonder by how much.. I bought a set of Eibach Pro-kit springs for my first Gen BRZ. The weight and balance of the car didn't change much, I wonder what the chances are that the springs will fit.

Despite the changes to the track, the chassis, and the tuning, the geometry of the suspension apparently hasn't changed.


Like the original, which has been around since 2012, the second generation of the BRZ is a collaboration between Subaru and Toyota, which will again sell its own version called the 86. Toyota once again handled the design, while engineering and construction are Subaru's end of the deal. The sports car's chassis carried over, but some new materials and adhesives taken from Subaru's Global Platform have increased the rigidity of its front end by 60 percent. "The stiffer chassis allowed us to stiffen the suspension mounting points, as well as the suspension tuning itself but still with a focus on improving its ride quality," said Michael Redic, Subaru's car-line planning manager for the BRZ, WRX, and Forester.

Subaru's engineers also made a slight increase to the rear track. The geometry of its strut front suspension is unchanged. There's still some body roll but less than before, and the compliance of the suspension feels right as Speed bounces the car off the track's tall curbs and runs it out over the rumble strips.

Maybe I'll hold on to these springs then... I'll drop them in and see how she sits. Car weight and balance is basically the same, so if the suspension geometry hasn't changed, I can't see how these wont work. I think a 0.8-1.0" drop along with these wheels I still have will look awesome.

GR86 - just came in - suspension is hard and stiff. standard/MT. My 1986 supra had suspension adjusters (a button). Can't quite figure that out or if it exist. The original design had a center "third" button for (sport/snow), but did not seem to make it into the main production model.

So far, 3 days, fun - go cart on the freeway!

This is only available on the AT cars, the MT has a blank in the centre of the three button area.

Lowering springs for the 1st gen cars will fit no problem. The only thing that I have not seen yet is how much drop they will actually get. The gen 2 cars are already 0.5" lower than the older cars. So if the old eibach kit was intended to give the old cars a 0.75" drop does that mean it will only drop the gen 2 0.25"...?? I would love to see the results.
