If it wasn't happening on standard brakes it's probably not really rear becoming light but incorrect brake balance. Try tweaking with different rear pads.


Dos it lock rear before the fronts?

does sound like a plan as the the front does nose dive and feel's like the rear lift's will have a play with the shock setting's and see what happen's

Shocks themselves won't help I'm afraid. It's rather in spring rates.

Default could

could slip a set of coil overs on there then you can adjust them to how you want. it could have been doing it before but not as much then wen you uprated the brakes they are now working a lot better so you notice it a lot more now
