As always, there were a lot of conversations about rules and cars at the runoffs. One of these conversations concerned polishing or REM treatment of transmissions gears and components. The GCR clearly states that only permitted modifications can be performed on components.
9.1.1.6F says, "Allowed modifications:Installation of any standard VW gear set which can be fitted without modification of any component of the transmission or of the gear set itself and the transposing of the ring gear to provide proper axle rotation. Permanent attachment of the synchro sleeve to 3rd and 4th gears is permitted."
When the REM tumbling/polishing process first came out, Bob Lybarger and I discussed the issue and decided that since it removed material during the process, and was not expressly permitted by the GCR, it was illegal. Vees have been disqualified for polished gears in the past and would be still considered illegal regardless of the procedure used.
I strongly advise those considering the REM process to think twice. You'll be exposed to protest and not likely to prevail.
