You may see rare rubbing in the front if traversing uneven surfaces at speed if you go with the 15mm spacers. 20mm in the rear will be fine as you have camber arms.Ideal fix would be to get some FUCA. Alternatively, you could go with 10mm in front. Either way, I would go with type I spacers in front and type II in the rear.
