PN: 21004-AT004This kit has been developed as a result of the knowledge and experience gained from extensive testing in the D1 Drift machines and Tsukuba Circuit time attack machines. As the kit uses the same bore pistons no additional machining work such as boring or honing are required for installation. Once installed hp and torque output will be increased all throughout the power band and internals will be reinforced to reliably handle up to 550ps or 50kgf/m!!

“ THE CUSTOMER'S VOICE ”
RHDJapan Store Reviews
Just amazing the build quality and style Review by Ihsan
Very good quality bucket seat. Comfortable and adjustable. Arrived very well packaged and the carbon is of very good quality, high quality of manufacture. I highly recommend this product for purists and those who appreciate this type of seat. Expensive but it is worth it because it is the quality of manufacture and materials that you do not find on replica seats.
Great sounding exhaust Review by Dave
The exhaust sounds great! It has a refined tone and isn't going to upset the neighbours with loudness.
