what manufacture should the shop that would be installing the custom gears work with to get the gears made?

looking to re gear my lr2 for stage rally racing here in the states.

Subbed for interest, wish I could help. I'd start with whoever builds custom PTUs and diffs for rally racing.

Also watching with interest.
Will the vehicle have a full internal roll cage ?

Came across these coilovers . Was thinking about whether or not they'd be suitable for rallying/off roading.

Yes, I worked with ceika to get a totally custom inverted three way suspension kit produced. They can make the suspension and brake kit for the freelander 2 but not the camber plates. That's odd... So I am getting way better camber plates for $1,500 usd. These plates are going to allow for the camber to be adjusted without having to drop the suspension.
