As someone who once had the "grind" and learned how to drive the car so as to not grind, try slipping 2nd the slightest bit. I can't tell you for 100% sure what I've changed in my driving "style" that eliminated the grind, but I can drive as hard and shift as fast as I want, breaking the rear tires loose through 3rd gear shifts and I never grind anymore. I do remember trying a number of things, one of which was forcing myself to "slip" 2nd the teensy tinsiest bit.

Don't get too excited yet...it's a "new" thing so you're subconsciouly driving slightly differently than you were before which is usually all it takes to not grind the gears. Give yourself a week or so to fall back into your bad habits, and then report back if you've ground since...

Still, you should let the clutch get a little bit used to the driver for the first 350miles or so.

It does bring up an interesting consideration though...Most have been focusing on the issue being mechanical in nature and caused by the transmission. Could it, instead, be an issue with the clutch or clutch-linkage? It's already been proven on other forums that an aftermarket clutch stop in one car will exacerbate the problem, but if moved to another, "identical" car, there will be no problem at all.

So could it be more of a problem of clutch engagement adjustment such that a decent percentage of the clutches aren't adjusted properly and, instead, have their full-engagement position at or possibly beyond the point of full-pedal travel, whereas it should be a bit before?

Seems logical, but I'm not an automotive engineer (I did, however stay at a Holiday Inn Express last night...)
