Interesting thread!

I am thinking of rebuilting my '02 WRX transmission with STi RA gear set. I made some calculation and it seems that the ratios with the 3.90 FD will be similar to a STi 5spd 4.44FD (non-RA), except for the first gear that will be quite a bit longer.

If someone have done it before, what's the feeling of it? is the first gear too long when you start from a complete stop, or is it fine?

STi Gears
1st 3.166 * 4.44 = 14,05704
2nd 1.882 * 4.44 = 8,35608
3rd 1.296 * 4.44 = 5,75424
4th 0.972 * 4.44 = 4,31568
5th 0.738 * 4.44 = 3,27672

WRX with sti RA gear
1st 3.083 * 3.90 = 12,0237
2nd 2.062 * 3.90 = 8,0418
3rd 1.545 * 3.90 = 6,0255
4th 1.151 * 3.90 = 4,4889
5th 0.825 * 3.90 = 3,2175
