Drop question

getting a truck or a second car. if you do a 1.5 inch drop and try to haul a trailer it probly wont look good. and if anything use tokicos, they would be stiffer than the kyb's and would hold up better.

The tein s-tech is going to drop your car over 2 inches. The TRD will drop somewhere between 1.1 and 1.25 inches. Also keep in mind the teins are a linear rate spring where the TRD are a progressive rate spring. Here is a link that will help answer some of your spring questions -- http://9thgencorolla.com/forums/viewtopic.php?t=1515

As long as you are changing struts too you might want to consider koni adjustables. You can keep the rears fairly soft for normal driving and firm it up for towing.

What you really need to find out is the total weight of the bike and trailer along with the tongue weight. The tongue weight is what will decide how much towing the trailer is really going to affect the rear suspension.

With a trailer that light you are probably only looking at 50 to 100 lbs tongue weight, this is the actual downforce on the hitch.

You will probably be ok with whatever lowering springs you want to use as long as the drop isn't too severe. I would suggest hitching the loaded trailer to the car then using a piece of string (2 inches to represent a 2 in drop, 1.5 inches to represet a 1.5 in drop, ect) dropping from the fender to kinda eyeball where you want your drop to be with the trailer. This won't be exact since your new springs/shocks should be a little stiffer and not drop quite as far with the trailer hitched but should give you a good ballpark of what you are looking at. Once you know what your drop to be then start looking for springs in that drop range.

Also keep in mind that some lowering springs tend to settle a bit over time giving a bit more drop than expected. This can be up to one-half inch depending on the spring while others have virtually no loss in height from settling.

Linear rate springs generally will give a firmer/bumpier ride than progressive rate springs will during normal driving. Linear rate springs are also cheaper than progressive rate springs.

I don't have all the answers, just some things to look for. Hope this helps.
