So I just kind of learned about the whole unsprung weight idea and how bad it is to have mucho unsprung weight-would getting really light rims be a big increase (relatively big I mean as far as smaller mods go) in acceleration>? And if so what are the lightest wheels out there within a semi-reasonable price. I mean I am sure someone makes ultra ultra light wheels for 10k but I am talking somewhat reasonable pricing

The Dinan wheels are 19lbs a piece and reduce the weight by 47lbs total for the car. The bad part is that they run you 1299 per wheel. Their exhaust runs 1499 and is lighter than the standard one as well. They don't list the difference in weight though.

My Ride: 545i SE Oct 03 (53 plate) 19" Alpina Classic rims
Quick question, apologies if this is a semi thread hijack...
can anyone tell me how much lighter the Alpina classic 19" rim is compared to stock?
(in the weights savings you mentioned above, does this take into account the presumably lighter tyre weight of a lower profile tyre? or is it for the rim only)

Breaking and agility, not acceleration . In other words, you make better also the acceleration, but only a bit .
