I presume you are running staggered ribs as its such a high bite surface - such as Belgium..

The natural thing to do, is go to Minispikes on the front (Schumacher or GRP, GRP seem to steer without it being OTT), then if still more is needed - go to Minipins.

Do try all the things listed by Ellis. Starting with 4+2 cell layout.

If you need 3+3 for 4wd, then look into doing a 3+1+2 cell build so they can be fitted in the X-6 as a 4+2 and used in your 4wd as a 3+3..
