I've finally (today) completed my full BRZ build, and thought you might be interested in the specially built Öhlins TTX/TPX rally dampers I have had built to fit the BRZ...replacing an existing set of Ohlins SUS MP21 R&T.

(I've tried to build my perfect interpretation of a useable daily driver tarmac/dirt rally car, that is still comfortable, reliable and can cover large distances.
It is producing around 350 HP and a touch over 400Nm at the rear wheels via a Harrop supercharger controlled via a Motec. I had a priority to keep weight down, and with a full tank of fuel, it sits at about 1260kg. But with aircon and an OK sound system.)

Fronts are a twin piston strut with a 44 mm piston (TPX 44) and 3-way adjusted with 1-way rebound and 2-way compression. The rear damper is a twin tube damper (TTX 44) with a 44 mm piston and 3-way adjusted.

I couldn't find anyone here in Australia, or the USA, who wanted to take on the challenge...and eventually found an amazing Ohlins rally suspension specialist in Holland (Leo at Madeno Racing) who has produced the most incredible dampers....after many emails, cad drawings, photographs, measurements etc etc.

My stipulation was that they had to be a direct "bolt in" to a standard BRZ/86 suspension set up...but then have enough flexibility of adjustment to be able to cope with a number of different possible set ups.

The TPX and TTX had to be completely re-engineered....including being shortened to a huge degree (Rally dampers have a huge amount of travel...and our cars have a very small amount of travel...sadly..).

The dampers come from the factory with no front mounts, and incompatible rear mounts, so every thing had to be custom made from scratch.

On advice from the builder I have fitted softer spring rates (40N/40N compared to my existing SUS MP21 rate of 60N/60N). He ended up fitting Eibach springs with helpers.

These are the finished beasts....

If there is any interest, I can post comparison pictures and development pictures.
