Chiming in on an old thread. I've been through a similar freshening of my car, and run the TcKline DA's.
You need to replace every bushing in the car. If they've never been replaced, they are worn and definitely need to be replaced. If you can't tell for sure if they have or have not been replaced, definitely replace them. You don't want to have a massive failure at speed.
You mention you just have your shocks set to full stiff. Why? Have you tried softening them? Excessively stiff shock settings can cause a lack of traction. I would also think that your description of what the problem is needs to be better. Is it sliding at turn in, at apex, at track out? Issues under braking, under acceleration or steady state throttle?
The basics of suspension setup and tuning on a 318ti apply to all vehicles the same. Make sure everything is in 100% perfect working order, make sure the handling issue isn't related to a worn part or worn tires first. Get yourself a proper track alignment, nothing to aggressive, but both the front and rear wheels can benefit from some added camber, -2 to -3 degrees in the front. I like a slight amount of toe out in the front, or zero toe or slight toe-in in the rear.
If the car is swapped, what kind of shape is the differential in? Is it stock?
Knowing exactly where the problem in handling exists will help you figure out if it is suspension related or drivetrain related. Should be easy enough to know where the car is going into under/oversteer and what your inputs at the time were. That is essential information in terms of tuning a suspension.
You definitely need to go look at your springs and see what the rates are. TcKline has a tendency to make the rear end way to soft on these cars, but that should help with rear traction. Losing the rear sway bar also greatly helps with on throttling traction. I don't, and haven't for a long time, run a rear bar. |
