I plan to race my car full time in BS. Normally I would jump on the KOnis, but the MR2 Konis are almost 70% more than the ones I paid for for the Miata. I dont understand why it is so much. Are there advantages to the Konis other than the lifetime warranty? Why should I buy the Koni over the other two? lastly which one rides the nicest? I have the KYB AGX with the TRD springs now, the ride is unbearable. Are the Tokicos or Koni on stock springs going to be better?
