it could be the control arms/bushings and as tom said balancing the tires might help, but also check to see that your tires are not cupped, if they are, balancing will not help and you have to get new tires. alignment would probably help too. also it could be the brake rotors are warped real bad. does it shake worse when you brake?
If no one has changed the chip, it should do 135mph before the rev limiter shuts it down. One thing about balancing tires. If the person doesn't split the weight between inside & outside the rim, say it takes one ounce to be balanced. 1/2 ounce should go inside the rim and 1/2 ounce should go outside the rim. Also when mounting new tires, the coloured dots mean either where the tire itself is heavy or where to align the tire to te valve stem. I'm probably not right here but say the red dot aligns with the valve stem. Tire manufacturers will tell you where to mount their tire in relationship to the valve stem. Giving my age away here, many years ago garages would use a spin balancer with the tire on the car. If the brake rotor was out (threw a weight or whatever) just balancing the tire wouldn't balance the whole spinning assembly. Guy's have written on many forums their 325 shakes at speed, the cars are prone to this etc. It's not true. I mount & balance my own tires from the Tire Rack. Never have I experienced the steering wheel shaking out of my hands. It is wize to raise the car every now & then to grease tie rod ends and inspect bushings. If the rubber bushing (s) are cracked or split or you can feel back & forth play on a control arm. I'd say the car would most likely shake a bit at speed. What I find most disturbing about some people is, they have no idea the condition of critical bushings or suspension componants when they go out & set land speed records on public roads. "yeah, she'll do 180mph, I was doing 130mph over here." I notice the drivers front tire has only three lug nuts holding it on....This guy was working on a ball joint and had the nut off it. He came over to borrow a pickle fork to remove it.
wheel balance needed, alignment needed, also replace the tires if they are old, no ABS they could be flat spotted, also replace suspension bushings if they are worn, urethane is the only thing worth replacing them with, also if you run out of power, and the car slows it self down, might be your ECU say no more cause it is an E.

the top speed on the 325e is approx. 121-122mph.
You were half right Ben. The stock top speed is 122mph but there is no such thing as a govenor on any E30. There is a revlimiter but it doesnt come into play because our cars dont make enough power at redline to push through the revlimiter in 6th.
My top speed actually increased when I got the 3.25ls diff, or it might have been the engine mods.
Oh well, either way I can beat 122.
