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.

They did run rear coilovers, but the rear rate wasn't that high. It was closer to the equivalent of a 1100 divorced spring - so I was told when I spoke with them about it.
I mentioned that exact point to them as well, the 300 split isn't consistent. As you go stiffer, that same 300# split becomes more front biased.
OP, glad to hear the softer front springs worked out. Nice lap.
