Lightbulb Manual in M3 compared to non-M3

I currently have a E90 325i 6MT. This vehicle was designed for economy not performance. Hence in the manual, the gear ratio's are much taller to encourage early gear changes. also, the clutch had a delay valve installed (until i removed it) which was supposd to gently engage the clutch for smoother gear changes.

now i am almost certain that i will order a manual M3, i am curious if anyone has any experience in directly comparing the transmission of a manual non-M3 E90/92/93 with a manual M3 E90/92/93.

I have read on forums that the gear ratios are different, the final drive ratio is different, and the clutch action is more direct. all this would lead to a more pleasant driving experience for the spirited manual driver.

it would be great if someone could provide an evaluation of the differences between the two.

I have an E90 M3 6MT, lets compare it to a Mini CooperS;
the minis transmissions was smooth and easy. For long drivers it nailed it.
But w/t the M3 transmissions it's hard to drive but rewarding. If I'd do it all over again i'd get the DCT b/c it's fast and more livable.. I can never drive my parents or GF in my car b/c it get really annoying. Only I enjoy it.

My suggestion if it's an everyday car and you want to be fast get the DCT.
-Still I love my M3 but like I said If i'd do it over again it would be the DCT; + they fixed all the issues.

I had a 2007 E90 328i and now a 2010 E92 M3. I would say the MTs are similar in feel and clutch action. The 328i but have been a little more forgiving but only a little. The 6MT in the M3 is a very easy MT to drive IMO. WAY, WAY better than the 6MT in my last car, an Infiniti G37S.

The gearbox is identical between the M3 and 135/335 - not sure about the other 3xx models.

The M3 does however have a shorter final drive ratio than the 335 (3.85 in the MT M3 vs 3.08 in the 135/335)...
