Small update on this,
PMS shifter now at a point where its tolerable.
One issue i have to admit wasn't the shifters fault but was causing an issue selecting 5th. This turned out to be a worn selector ring on 5th gear which was causing an intermittent notchiness to it engagement. Not sure how this was missed when the box was built as its had all new bearings and synchros?
A new selector ring has cured this issue. This compounded the hideous buzzing of the shifter and i was getting ready to rip it out and throw it at someone!
At the same time we refitted the PTFE lined bearing that i had removed the preload on and thanks to
@perazzi who supplied me some lead shot for the link rod.
The PTFE bearing/lead shot combo has made a significant difference to the resonance inside the cabin and for the most part the shifter is silent at almost all rpms. The shifter finally feels smooth, tight and engagement is clean.
In addition to my "perfect road spec 182" i have just collected a brand new set of 2118s with some R888s for summer use and after much discussion ordered a set of AST5100s which i have specified are for fast road use and are to be valved/sprung accordingly.
Hoping to use reasonably soft springs so the car rides properly and still maintains exceptional chassis control that exceeds that of the halo'd Trophy.
We shall see lol, so much for keeping it standardish
