Help finding 964 race spring perches

[wastintime]

Hey everyone,

I want to lower my RS America before going to the track in September, but I also don't want to change the spring rates at the moment. I was wondering if anyone knows of a source for modified spring perches that allow you to lower the car with your stock shocks? In other words, rather than the standard spring perchers which sit in the middle of the threaded portion, are there any available with maybe a 1-2 inch threaded portion above the perch itself.

Thanks,
Andrew
