I'm buying a new Z3 and want the Recaro seats. They're
standard on the sports package, but this also gives me
stiffer suspension. I'm concerned it will be too stiff
for these mountain roads I drive on (bad surface usually).
If I bought aftermarket seats, would it affect the warranty?
Would the 17" vs. 16" wheels make much difference? I was
thinking, maybe the sports package w/ 16" would work.
