How does the throw compare to a stock m46/m47?
I extended my m47 shifter 15mm, and it’s what I feel is a good OEM throw now. Next one will be 20mm I think.
The limiting factor is usually the rubber joint on the transmission and driveline, as the bottom of t shifter gets close to that.

No idea if the m46/m47 can be compared at the m90

Have you measure the movement before and after ?

My m90 short shifter was extended by 15mm below the pivot ball - feels good to me, I donít think Iíd want it to be any shorter.

Cheers

I too extended 15mm below the pivot on my M90.

4cm sounds too long, I'd expect you'd end up hitting the driveshaft.

The guy who told me 4cm is a CENSURED is for this I prefer ask here for have conformation and feedbacks

I test 15mm or maybe 20mm but not more

Is some one have the measure from the movement before and after is appreciate.

The stock length from pivot ball to the center of where the shifter fork attached is about 30-40mm, so adding 15-20mm would result in about 2/3 of stock travel.

I added about 20mm, feels about right, on my brother's car we did a little more ~30-35 but changed it back since the force required for shifting was a bit too much;)
