| Remark | When using the Big Operating Cylinder, the stroke amount of the cylinder decreases, so please adjust the stroke as necessary. 1) Be sure to clamp the hose with a hose clamp to prevent air from entering before removing the standard operating cylinder. 2) Fill the Big Operating Cylinder to be replaced with Brake fluid, remove air beforehand and connect it to the Hose. 3) Even if you do 1), 2) work, air enters the piping. Once the air enters the piping, the pedal stroke and feel change. Because it is difficult to remove air from the thick diameter U-shaped pipe etc, please bleed sufficiently. 4) To facilitate the work of 3), air bleeding by vacuuming is effective (Please use the U-shaped pipe dismantling adapter attached to the NISMO clutch hose). |

Color and fit
Love the suit style. But the color wasn't what I expected. Was to be beige but appear to be more on a light pink. Also the fit was on the small size due to my awkward body size. Seller went beyond to solve my issue by having suit replace with a different color and adjusted size to fit. No questions asked. I was very satisfied.

Great suit, I'm gonna order more!
Bought this suit for a funeral and felt really sheek and unique. The buckle on the wrist and the right side really adds an impeccable fit and makes a sharp statement for anyone slim or chub. Worth the try if even a one time buy!
