this may be an insanely stupid question, even better that its my first post. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/cool2.gif)


i recently noticed that my regular old rubber valve stems have cracks in them, and im afraid theyre going to, or already are leaking.

im interested in starting autox, or road racing (the course at englishtown.) so id like to get everything in tip top shape.


i found an old thread here mentioning these types of valves:

are these appropriate for street use? are they overkill? are there any down sides compared to regular all rubber valves?

thanks in advance.

Wow. Must say I'm surpised at the responses - keep in mind I'm still new to all this. However, I recently had a rubber valve stem fail on me right in the middle of turn 12. Left front tire too. The valve had failed right at the wheel. Since steel ones wouldn't have this problem, I thought they would be the way to go.
