The only difference is in the actual model of the gearbox (128i has GS6-17, 130i has GS6-37), and final drive, mine being shorter.
hence, I'd still say the 3.85 is an awesome idea (and at the very least, the 3.46 would give waaaaaay better acceleration anyway) :P
very confusing though... why did they release the lower power 128i with LONGER gearing than the higher power 130i?... did they want to make the 135i seem even faster in comparison?.. so no, seems like BMW didn't do a very good job with the 128i gearing as a 'sports car'... surely decent as a highway cruiser being quite low revs at highway speeds (mine being 2500rpm @ 63mph)

Totally agree with you! I have always thought what is the point of having 6 speeds (or whatever the number is) if you dont use them all, the 128 reaches top speed little after changing from 5th to 6th and at about 5.5K rpm, the 130i though, it reaches max speed at max power rpm point, so it is a true 6 speeder, and it can actually almost go all the way in 6th to the red line if limiter is removed.
The 128 NEVER will run like a 130i for several reasons, this is one of them, unless of course the owner swaps all missing bits.
128i hits 100 mph in 3rd, the 130i is already back in the power band in 4th at 100mph.
I do hate long gearing! and back to the point of the TRW bits, I just bought them, will share pics onces I have them. I do believe the only diff is the sanded down //M logo, which is just nothing to worry about since those things live in the filth all the time anyway
