I looked up some 0-60 and 1/4 mile times for e36 M3 and 128i. For the e36, a 1995 was listed as 6.1/14.4 and 5.4/13.8. The only 128i coupe independent test I found was from Car and Driver of 5.8/14.5. That is very similar to the 1995 but not the other time, I think it was a 1998 or 1999. Those were 3.2l motors with more torque so it make sense that this plus the gearing would make the e36 a little faster.
I find this article interesting on the subject of handling modifications:

I do not plan to do all this anytime soon. My next step is to replace the stock runflats with non-run flat tires, probably Contis, maybe PS2s, with the fronts the same size as the stock rear tires. I might also remove the alignment pin and have an alignment to get a little (maybe half degree) negative camber.
