Inquiries on Boss
Q: What product number is appropriate to my car ?
A: Please fill up inquiry form.
Q: Can an airbag fitted steering be converted ?
A: Yes, it could be converted. A dummy harness for air back use comes with our steering boss hit for use with air back. Using a dummy harness will disable the air back warning lamp. (In some cars, the air back warning lamp cannot be disabled).
Q: If the steering is converted, will it pass mandatory inspection?
A: The steering boss is part of the mechanism to dismount steering and is an important safety device. Conforms to car inspection standards, hence it supports car inspection requirements. For the steering wheel, please inquire from the steering wheel manufacturer.
Q: Can the boss be used in cars of the same type?
A: For same car types, if the year model, car model and rigging are exactly the same, the boss can be fitted. If even one of the year model, car model and rigging is different, it is possible that the configuration of the car is different, hence, a different product number may be appropriate. (Some cars may have different configurations even if the year model, car model and rigging are exactly the same. In such cases, it may become necessary to check the configuration of the actual car.)
Q: After fitting the boss, the horn does not sound off at all. Why?
A: For horn contact plate (brass plate) type cars, dimensional difference, the car side causes the horn not to sound off. Parts to address the problem are available, however. Please inquire from the store of purchase. (The part may not be used in some cars, however. If so, please discontinue fitting the boss.) For Coupler type cars, the horn fuse may be busted or the wiring is broken. Please consult professional service (sales outlet, dealer).
Q: Can an air back fitted steering be converted?
A: Yes, it could be converted. A dummy harness for air back use comes with our steering boss hit for use with air back. Using a dummy harness will disable the air back warning lamp. (In some cars, the air back warning lamp cannot be disabled).
Q: After fitting, the horn does not sound even after a while. Is it damaged?
A: The horn fuse may be busted or the wiring broken. Please consult professional service (sales outlet, dealer).
Q: My car is not supported but I want the steering converted. What should I do?
A: We manufacture custom made steering boss. Click here for details.
Q: After fitting, the air back alarm lamp does not light off. Why?

A: Please conduct the following tests.

[For manually inserted dummy harness]
1. Revert to original steering, and check if alarm lamp lights off. (If lamp does not light off, please consult sales outlet or dealer.)
2. Re-mount the boss. Attach the harness firmly using tape or other means so it will not be detached. Likewise make sure that the fuse is securely attached to the dummy harness.
3. After fitting to the steering, check the alarm lamp. If lamp does not light off despite the above procedure, the lamp may not light off due to some differences in the car.

[For SRS Coupler]
1. 1. Revert to original steering, and check if alarm lamp lights off. (If lamp does not light off, please consult sales outlet or dealer.)
2. Remount the boss, mount the steering and check alarm lamp. If lamp does not light off despite the same procedure, the lamp may not light off due to some differences in the car.

Q: After conversion, where shall the position of steering be?
A: This varies with the steering wheel design. For flat type steering wheel, it is almost the same positioning as in the original steering. (For some cars, a boss spacer might be needed.) When if cannot be drawn near, use a boss spacer sold separately.
Q: Can auto-cruise function still be used after steering conversion?
A: Yes, it can still be used through the use of horn button that comes with the steering boss for auto-cruise use. When using the different horn button, use a switch key sold separately. (Auto-cruise function may not be useable in some cars.)
Q: What is the difference between mechanical air back and electrical air back.
A: The form is clearly different because air back action is different. Electrical air back has the air back alarm lamp inside the meter.
Q: Can a steering boss for use in air back cars be fitted in non-air back cars?
A: No. The configurations are completely different. Of course, the same is true for the opposite case.
Q: Please tell more about the tightening torque for the center nut.
A: Make sure to apply 3Kg·m of tightening torque. For details, click here.
 
Inquiries on Rapfix
Q: Does RapFix satisfy car inspection?
A: RapFix conforms to car inspection standards, hence, it satisfies car inspection requirements.
Q: When RapFix is attached, how close at hand is the steering?
A: The total length of RapFix is about 60mm. It comes closer at hand by 60mm from the normal boss mounting position. Used together with the exclusive short boss, it is drawn closer to the column side by 20mm ~ 40mm, (The length differs with product number)
Q: Is there no chatter?
A: There is absolutely no chatter when a new article is fitted. Even under WRC and such harsh conditions, there is absolutely no chatter. However, product life is determined by the wear of contacting parts depending on frequency of use. The details on economic life are under investigation.
Q; About mainmaintainess
RAPFIX was designed resting on the premise that dope may not be used. Since the foreign object caused by grease will influence the life span ofthe product. The ball is made by steel and cannot resist rust perfectly. Theproduct might not work badly because of the attrition of the ball. A way to cope well wth this problem is to use parts cleaner to clean the attrition sediment. We also recommend applying dope (CR-C) only on the ball by cotton swab.

*Avoid applying too much dope on the ball and do not apply dope on other parts except the ball.
