Compact doesn't stop properly on gravel.

Had the maiden voyage in the '98 318Ti on the weekend. Great fun, lots of potential, expected new-car niggles.

One unexpected issue is that it doesn't pull up very well - no matter how much traction there is, it feels like half the traction disappears when you are braking. Feels like an issue with geometry or suspension, rather than a brake problem, but could be a brake bias problem.

Standard brake hardware with Ferodo DS2500 pads. Fresh fluid, ABS disabled by removing sensors. Pedal is lovely and firm.
Suspension is a set of rally valved Bilsteins that work beautifully everywhere except for wash board roads. Stock springs F&R. Camber tops.

Any ideas?

TIA!

E36 has anti dive geometry
Have you raised the ride height in front for gravel use
If you lower the the rear mount on tca it will reduce anti dive but be very careful how you achieve this needs to be strong and safe
We use a pedal box and had to put 4 pots calipers on front to help slow car down when we eventually got car going fast
Enjoy!

That makes sense, thanks.

Any suggestions on how far to lower it?

Ours is only about 20mm have not experimented with different amounts yet
our front spring is a bit stiff waiting to change to a better shock to try a softer set up to transfer more weight to front ,under braking
