And here is the pièce de resistance:
I needed new brake calipers because my old zenki models didn't like too much what they took last time I went driving on the Fuji Speedway.
I was about to buy a used set of AP racing calipers with two-piece rotors but after taking with Mr. Nagashima, owner and pilot in the Okabe Jidosha Motorsport (which where my car come from), on his good advice I decided to go for stock Spirit R calipers. As a matter of fact, Okabe Jidosha race cars are set with this calipers and according to Mr. Nagashima and Mr. Yano, this is the best system for an FD on the track (better than any other after market brake system for this car actually). To get along well with these, I ordedered Dixcel FS rotors and Type Z brake pads (still like what OJM uses on their race cars).
I entrusted OJ for the installation of the brakes as I don't have any equipment to do it myself yet.
They called me when the work was done and I was invited to be there when the did the brake test on the bakre tester then we lifted the car to check together that there were no leeks anywhere. Dot 4 fluid was injected and the even replace the brake fluid reservoir's cap fro free. (Trust me, Japanese service is the best on the planet)
The feeling is perfect. Brakes effective as soon as I touch the pedal but really progressive and easy to control. Definitely a excellent choice for brake upgrade and more over, it's half the price of a used AP racing system which would have given me nothing more but trouble.
