The main advantage is the rocker can't slip off the valve at the wrong time. With the stock springs the rocker can slip sideways and not stay on the valve. Car then runs like crap! This can happen if you over rev the motor.

The spacers take all the "play" out of the valves... With the spring type high RPM and fast opening rates can shift the rocker sideways a few degrees after the valve starts to open and change valve timing.. The springs can also break. these solid spacers won't do that..

Yes they are.
I wasn't sure if a street teener would really need something like this. Sound like, from the replies, a high rev'n engine could benefit from these. Since mine is a street car with minimal time in the red zone I think it is less of a benefit. Cheers |

(IMG:http://www.qtm.net/~persoj/graphics/vw/rockers_1.jpg) These are FAT spacers - They are cheap, BTW. I'd put them on a stocker without even thinking twice. Also, get the FAT 8mm rocker studs. That's another no-brainer. Tom |
