Dropped ZHP and now have some Thoughts/Issues...
 
Well, after I drop my car on EiBach Pro-Kit and Koni FSD. I have some issues and not sure were they are coming from...

I started to have pulsing problems after I Dropped it when the brakes are applied. It has Brand New OEM FCAB (only about 4k on mileage). New front Rotors and Pads.

Steering Wheel is not tight anymore...:( When I hit a bump on the interstate or anything the steering wheel moves back and forth. Not as solid like it was before.

I still have the problem of my car still going to the right...:( I have to hold my steering wheel straight or sometimes to the left to keep it going straight.

Front Left and Right Camber are L -1.4 R -1.4
Front Left and Right Caster are L 5.2 R 5.3
Front Left and Right Toe are L 0.10 R 0.14
Front Total Toe 0.24
Front Steer Ahead -0.02

The Mechanic told me that my Front Toe cant be even/balance cause of windhead? Supposely it keep my steering wheel straight. Is this some BS?

Rear Left and Right Camber are L -2.1 R -2.0
Rear Left and Right Toe are L 0.13 R 0.13
Rear Total Toe 0.26
Thrust Angle 0.00

I love the ride but not sure what causing all this problem...Wish I get it all worked out and enjoy my new car...

Edit: So for it has

Eibach Pro-Kit with Koni FSD
Meyle HD RSM
Rogue RTAB Limiters
Front OEM FCAB (only 5k)

you have a ZHP, why did you feel the need to drop it? why not leave it as is? modding a ZHP defeats the purpose of buying one in the first place since it's upgraded with a "performance package." it already comes modded from the factory. i'm not saying our cars are the "be all and end all" of the BMW lineup, which belongs to the Ms, but didn't you get a ZHP so you wouldn't have to mod...or mod as much?

with that said, i hope you get things fixed. doesn't sound like too much of a problem. i assume the shop did a wheel alignment after installing your new suspension? sounds like it might've been a subpar job causing an offset in the camber. this can easily happen if the wheel wasn't perfectly centered while the wheel alignment was performed. did you also install a camber kit?

Caster and camber, being different from one side to the other, can make the car pull. For example, you are going perfectly straight on a flat road and you let go of the wheel and it pulls to one direction. However, if the camber is the same on both sides I would think it is more likely a tire, caster, or other issue.

However, if the wheel has to be slightly turned to one direction or the other straight, but letting go of the wheel doesn't result in a pull, then the steering wheel simply isn't centered. It won't hurt anything, but it can be fixed by adjusting the toe. If, for example, one tire is toed in one half of a degree, and the other tire is toed out, the result is that it will actually track straight with the proper angles without pull. because of this, the steering wheel will be off centered slightly when going straight.

try to take it back to the shop and get it realigned.

^^^why NOT drop and improve handling even more?!? PLUS the fact that it looks 100 x's better dropped...

to the OP, I had the same problem when I dropped my old e46...I ended up replacing the control arms (MEYLE brand) and the bushings (POWERFLEX urethane) and problem was solved...

ROOFLESS 10-20-2008 01:13 PM

bouchet 10-20-2008 01:24 PM

hahahahahahahaha

^^^^^ Didn't the OP say he has almost new OEM FCABS?

On a serious note OP, those FCABS may not have tightened under torque, hence got damaged over time. Also, check your tie-rods and sway bar links.

why does it defeat the purpose? even with the new suspension, it still understeers a lot. suspension is better than the regular, but it's not like the best or anything. also he could have bought the car because of the way it looked. or for the 10 extra hp. not everyone bought the zhp because they knew what it was.

n2Bimmer 10-20-2008 01:46 PM

suspension issues are a PITA, good luck,

TrippinBimmer 10-20-2008 02:32 PM

I bought the ZHP for the looks and the 10 extra HP... With 19's it looks like it was a 4x4. I know what was a ZHP when I bought the car. So does the alignment look correct? I will get the Mechanic at the Dealership to look at the Front FCAB and Control Arms. Any more opinions?

TrippinBimmer 10-22-2008 02:09 PM

My car still at the Dealership (since Friday Morning at 7 am) and still haven't been worked on yet...:(

sillieidiot 10-22-2008 04:36 PM

lol it's always like that at the dealership.

cimper43 10-22-2008 08:19 PM

When people remove the front struts alot of times they place a pry bar on the control arm to force it down so the strut can come out. This breaks the inner ball joint of the control arm. When the control arm is all the way down the only thing limiting this is the balljoint.
