Reguarding the SAW products, if the truck is offroad alot, I would reccomend the tundra valving and spring rates. It's going to take away from the soft ride like you said, but your truck will thank you for the abuse you spaired it.
Are you talking about running the OEM Tundra front shocks and coils on the Tacoma? I've looked into it a little. You may have to reindex the coil buckets and be on your way? I've heard of it being done. It's cheap, but I haven't heard any feed back so I don't know how effective it is?
