Actually, it's been over a month since I waxed the car. Plan on giving it the full treatment after I get it back next week from getting the clear bra installed. I normally use Mothers 5701 or 5750 Carnuaba wax depending on if the car needs a full polish or not. 5701 is a combo polish/wax whereas 5750 is Step 3 of the Mothers 3 step system - Polish, Micro-Polish Glaze and Wax.
They won't be able to sleep, I'm sure...unless they're young. The feedback is quick and stiff for sure.
I've always likened it to 20% LESS stiff than the current generation M3. Is that what you're feeling?
Once it settles in, it'll soften a little (I noticed). It's like the springs needed a few hundred miles to settle.
