Re: E63 Rims
I've got the ACS springs on my stock shocks and it lowers the ride quite nicely over my 21"ACS type IVs. I hardly feel any difference in the ride. Comfort is still there, just a tad bumpier.
And yes, I had them all fitted when the 6er was delivered at PML but have been comparing it with the courtesy stock 6ers I've been getting during each service which to some extent felt too dampened. Nothing wrong with that as the handling is still as sweet when stock. So do it just for looks then.
