Hi Matt - the specific details haven't yet been printed.
I can tell you 12mm springs do fit from other manufacturers.
I do not think the 14mm hex would fit and I would recomend 12 mm as its becoming a uniform fitment amongst manufacturers. Certainly all are aiming for this to be standardised in the near future.
The front wheels are unique in their off-set as the wheel dishes inwards and are different to previous SRX4 type wheels
If you are local or see me, feel free to come and have a look...
ps - I don't get on here that often these days so excuse me for any late replies
