My Gt has TRD coilovers, and the ride is very firm but unless you go over larger bumps n stuff its really not that bad, pot holes are a bit annoying though.
i went in a glanza that im pretty sure had just been lowered on springs and it had almost no suspension travel at all it was like being taken for a ride in a tank. the steering wheel was all over the place and the driver looked like the car was going to shake him to bits.
