TRD shocks and springs

No, the stroke is not full. You get a full of rebound stroke (meaning spring release is still a problem even though you bought crazy short shocks) but you have no bump travel left. So the car bangs the top of the strut on every pothole. Great setup!

Beautiful way of wasting money. Lets see, the TRD shocks have more travel then the springs. So lets say the springs extended are 1cm shorter then the extended shock length:
165mm-10mm = 155mm
The AE86 strut extends around 100mm beyond the spring perch. so you are left with:
165mm-10mm-100mm = 55mm
of space between the top of the strut and the upper mount when there is no weight on anything. Now add the weight of car+driver. Assuming blue TRD springs with 6kg/mm rates:
static compression = 275kg / (6kg/mm) = 46mm
Remaining distance between strut top and top mount =
165mm-10mm-100mm-46mm = 9mm

So after spending tons of money on impressive sounding parts you are left with 0.9cm of bump travel. Awesome. This corresponds to a further load of
9*6 = 54kg. Add the weight of two passengers and you are on the bumpstop (if you left it in, most true idiots remove them believing its an upgrade to do so). It also corresponds to 0.2G of cornering force, something even my mother attains during her trip to the shops. Just to reiterate as soon as the strut touches the top mount you have metal on metal contact. No springs involved anymore. Very comfy. For those people claiming coilovers in the rear are an extra load, you should do the calcs on the loads without springs in the front. Sure fire way to screw up the chassis towers.

No bump travel, still problems with non-captive springs. WHY would someone do something like this? Just to get the TRD/HTS brandname? Are people really that stupid?

If you do decide to take this path. Please leave the bumpstops in! They have a 15kg/mm rate or so and they will save the chassis and shocks. The car will rest on the bumpstops permanently which is why it's handling will still resemble something sporty.
