I recently put a set of Kumho Ecsta MX's on my ricer STi.Kumho mades a really nice ricer tire.
They were installed by a shop Tire Rack recommended.They had the Road Force balance equipment.This shop mainly deals with high end performance/race BMW's and Porche.
They commented that by far Yoko's (ricer) were the best balanced tire out of the box than any other tire on the market.
And Pirrelli's (non-ricer) were the absolute worst.
