Seems odd someone like bimmerworld would recommend 800/1100 based purely on a "300lb/in split." That's just not how suspension works. 100/400 springs would be a 300lb split and actually be a pretty balanced setup since the rear spring rate is pretty much 1/3 as effective as it should be. 800/1100 is massively front biased. Bimmerworld races 328i's though so you'd think they have a pretty well sorted car to base things off of. Maybe their race cars have true rear coilovers? That would make 800/1100 much more neutral handling.

If I keep seeing 128i videos like this I am going to need to sell my 135i. I liked my NA 128i so much better on track. It actually like being at 6,000rpm+ lol and lifting a bit to change the cars balance didn't lose all your boost :/

1:29:9 at thunderbolt is faster than a spec e46. That's a damn fast lap.
