Today, we carried out Nissan GT-R Sachs suspension testing at Ebisu Circuit.
Ebisu Circuit is located in Fukushima prefecture, north Japan.

We have tested several spring rates, and finally we chose 1200lbs/in for front and 800lbs/in for rear suspensions.
Today's our best lap time is 1'01.495 in the 88F temprature.

We have done very limited modification such as ECU and suspensions sofar (not even exhaust muffler today!), and we are sartisfied with this result.

Tomorrow, we will have filming for Hot Version monthly DVD here, and four famous tuning garage's GT-Rs will gather.
