More than likely in some obscure thread this has been covered but no one seems to mention using non TRD coils as part of the front end lift? are the just not worth the time or is the ride with the TRD coils the much better? I can find Non TRD 2WD Tundras all day down here in FL, but have never come across a TRD 4WD wrecked. So whats the difference to us?
