A must-have item for sports driving has arrived!

The standard clutch slave cylinder has a built-in delay mechanism using a *1way valve to suppress sudden clutch engagement. While this structure provides smoothness in general city driving and daily use, it causes poor response and ambiguity in sports driving and high-load operation.

This product is designed to eliminate this delay mechanism so that the clutch engagement feeling is transmitted directly and linearly.

Advantages In Sports Driving Quick Shift Work

It operates without delay even for quick clutch operation, so there is no deviation in operation even during heel-and-toe or continuous downshifting.

Acceleration at corner exit: By accurately grasping the timing of clutch engagement, it is possible to extract traction in the shortest distance without disturbing the line.

Increased acceleration on straights: Since power loss is suppressed, engine power can be transmitted directly to the drive wheels, which ultimately contributes to shortening the time.

Ideal For Street To Circuit Users

This product can be installed regardless of whether or not you have a reinforced clutch, and is effective for users who want a response even with a genuine clutch. For those who want a more integrated feel with their car and a greater sense of control, this is one of the easiest and most effective upgrades.

More Comfortable than an Airbed
Color: light gray, Size: cot
I purchased this 4-inch foam floor mattress for when grandchildren stay over. This is my 2nd one, since zi have 2 grandchildren. I don't have room for beds or bunk beds, but I have a space where I can store these. I slept on it myself several nights in a row when I had company and I found it to be much better than sleeping on an air bed. I purchased mattress covers and fitted sheets that fit the exact dimensions of the mattress and I am happy to be able to provide a perfect sleeping setup for my 2 grandchildren! If you have a place to store the mattress when it's folded (25 inches high, 31 inches wide, 12 inches deep) I recommend a 4-inch thick foam floor mattress over an air bed. In my home it is the perfect solution! Follow all the directions for allowing the mattress to reach its full thickness. It is vacuum packed and needs several hours (almost 2 days) to expand.

Blow up beds are better
Color: Grey, Size: Queen
Blow up beds are better. These are barely thicker than a sleeping bag.
