I have a 2012 brembo car with 3.73s and MGW shifter. Question is I like to run the quarter mile alot. Is speed shifting into 5th all the time going to wear the blocking ring alot. Is the blocking ring on 5th a single? Is is just about as stout as a t56s 4th gear ring? Next question is, when I am rolling to stop I will sometimes downshift 2-3 mph into first gear it don't feel like it goes all the way in some times and i will go to let clutch out and it will pop out once and while. If i am a little more force full with shifter it seams to be way better. Car only has 850 miles on it have had 6 mustangs in past from 87 gt to 04 cobra so my shifting is not the problem. I did just install the qdc fluid haven't got a chance to take it out beings there is snow on ground.
