It's a nightmare over speed bumps but you can get over them. The best way is if u take the bump at an angle, then go over it by swinging the car the opposite angle. Will explain this again if need be, it's very hard to explain.
The ride is very bumpy, i mean if there is the slightest bump in the road.....u will feel it. It feels worse than it actually is. It all makes it up around the bends though! Grips like f**k! I raced an Audi S4 yesterday which has been tuned nicely, but he could not compete around the bends! Not just that, my 325i Sport is running some power
I use Koni adjustables on my car, however the H&R Kit on the E30zone are just as good. Recommend adjustables only if you're going to actually use the adjustable facility. I need them as i'm from London so the roads are all smooth (60 60), however when i visit some of my family in Brighton it's soooooo bad

speed bump, speed bump, speed bump! Therefore you will need to adjust the suspension & put it up a couple, maybe a few mils.
The tip of my front bumper is a little scratched from driving in Brighton, & one of my sump bolts had lost it's shape when the geezer who was servicing my car yesterday showed me. He said he was suprised that i didn't crack my sump................think a sump guard is necessary!
Alpina's is a must, PCW's do a nice set. Even got a slight sparkle to them!
Any questions geez, give me a shout
