Converting my 325i to 'suspension' sports package

I found this website that has prices on oem bmw parts and am thinking about putting in sport springs along with shocks. I don't want aftermarket because i want ample ground clearance and i just wanna stay stock.

What else do I need besides the accessories listed in this link?

I really don't think you need new shocks to go with the springs.

because the sport package along with my 19' wheels that i want would give me the look i'm after. On top of that, i'm still in factory warrantry with bmw oem parts. why not just stay like that?

that and the fact that the sport dampers along with the sport springs is a proven combo, obviously since it's available on e90 sport packages.

good answer. i dont know too much about factory, or aftermarket sport springs, but 1. im pretty sure no aftermarket springs or shocks will void any warranty. and 2. there is a reason why there are huge companies out there that JUST sell aftermarket springs (h&r, eibach). im not sure if these companies are soo successfull because they are able to sell their aftermarket springs CHEAPER than factory stuff, or if they are
succesful because they have proven to make BETTER parts then factory. I know its hard to imagine that a company might be able to make a part "better" than BMW. but i guess its possible.

the reason why i think these companies are successful?
good track record
been in business for a long time
aesthetically pleasing look of the car after their springs are installed
better handling with aftermarket springs, provided dampers and the rest of the suspension is in compliance.

i know for a fact that aftermarket springs can void part of my warranty, it's just common sense. If my dampers begin to feel bouncy when going over dips obviously i'm not going to be able to go into the dealership and tell them i need new dampers. stiffer springs (aftermarket) = early wear of dampers

if i went aftermarket, say eibach, i would want eibachs dampers to match along with their springs. installing stiffer springs with factory dampers is only asking for trouble a short while down the road. Does anyone know if i would jeoperdize any of my warranty because of oem bmw springs and dampers if i have them installed at an authorized dealership? we know that my car did not come with sports package, will this justify voiding part of my warranty?

i also forgot to mention my goals/intentions of the car.

daily driven car, will probably never see an autocross event. just normal day to day driving. Anything over the bmw sports suspension package (springs and dampers) will be imo overkill for what i'm doing with my car.

I'm after bigger lighter wheels than my 16' oem runflats/wheels, maybe 18's if i get greedy 19's, and the springs and dampers from bmw's oem suspension package. This will give me the spirited acceleration i like giving this e90 through the turns daily driving the car. anyone else agree?

Getting a matched set of springs and shocks are always a good idea!
