| 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). |

Fine but not great
It fit well and looked ok. However the material was thinner and flimsier than I expected. It was quite wrinkled and I couldn’t iron it well without risking melting it due to the polyester content. After ironing for about an hour on low heat it was passable but it was a lot of work to only get a passable result.

Definitely Worth It!

Love this set for my little Easter-man (Khaki - Size 6)! I have a husky 5 year old son. ( I was able to hem the pants myself although his pants slipped down a bit before I tightened his belt) Loved the overall quality for the price!
Kids play - it was the perfect material to give a good look but not break the bank. I purposely bought a bit large to ensure he’ll be able to wear it longer. I’ll be back for the navy suit.

Exceptional boys suit!

Seriously Great Little Suit! True to Size and Looked So Sharp.
I bought this blue suit in a size 12 for my son, and honestly, I was really impressed. You know how sometimes kids' clothes sizing is all over the place? Well, this suit was actually a true size 12, which was a huge relief. It fit him perfectly right out of the box.
And the best part? It looked fantastic on him! The blue is a really nice color, and the suit just looked really well-made. He wore it to a 6th Grade graduation and he looked so grown-up and handsome. We got a ton of compliments.
If you need a good-looking suit for your son that actually fits, you should definitely check this one out. We were really happy with it!
