That 5th gear is no good whatsoever even a 650+ Cossie cant pull it.
It will give you a theortical Topspeed past 214mph @ 7500rpm on 215/40/17
You can get a .83 5th gear for a TKO so I expect its available for the 3550 thats is within 3% of a T5 .
Below will give you the speeds @ 7500 on 215/40/17 using 3.64 diff
!st 45mph
2nd 74mph
3rd 109mph
4th 146mph
5th .68 214mph
5th .83 176mph

hi mate
1st gear is a bit short
2nd is ok
3rd is ok
4th is ok
5th is to low that a pure cruse gear
if you do go to a 3.9 1st gear will be even shorter not only that you will still struggle to pull the 5th gear
if you can go for ratios like 2.95 /2.97/3.00 for a 1st gear
2.10/2.07/2.00/1.94 for 2nd
1.50/1.45/1.4/1.35 for 3rd
1.1 for 4th
0.85/0.83/0.80 /0.77 for 5th dont really go much lower on 5th any of these ratios will be ok in a road car with the 3.64 or 3.62 diff
