Fronts for full spikes

[mekios]

We race, here in Greece, on an old Warehouse with polished cement. I am having trouble finding traction with my B4.1 so i am trying some Schumacher full spikes on the rear.
What type of tires am i supposed to pair them up front? Will ribbed tires work? Cuz i found that softening the rear or adding some toe in to stop the car from sliding on power kills steering dramaticaly. So ribbed tires, especially JConcepts groovy are really good. But with full spikes?
