A 153 Yes.
Armor spikes are weapons, not armor, and are only attached to armor to be wielded without hands. (The armor and the spikes are necessarily separable because each may be enhanced independently.) A Warforged will have additional time requirements, and may need help, to attach armor spikes; talk to your DM about that. The Spiked Body feat lets a Warforged have a similar capability without the extra equipment, and without the risk of that equipment being sundered or disarmed.
