A sample of Tnt's after opti coat, if you don't mind bro.

not a problem at all .... just been so busy haven't have time to post any pics yet

I test-drove an FR-S at a dealer with the Tein H-Tech springs installed and fell in love! I have them installed on my car now and it improves the look without changing the ride too much. Very rough bumps are worse, but the normal dips and potholes etc. feel about the same. You can feel a difference when you throw it into the corners!

I would recommend the Tein H-Tech's from personal experience!

Thanks. Just hear about those TRD springs all the time and figured they all were bad

lowering springs can wear out your shocks faster. the lower you go the more it changes your suspension geometry and the OEM shocks were designed to pair with a certain set of springs, the OEM ones. A lot of people accept the risk and get the springs anyways because they want the look, for cheap. Shocks will probably still last a few years even with lowering springs so most people won't care. The "proper" way to lower your car is with coilovers (which are designed to allow adjusting ride height without changing spring rate), or a matched set of springs and shocks (a fixed change in ride height). For instance on my MR2 I added Eibach Pro Kit springs but also upgraded to Koni shocks at the same time. Still no problems some 10 years later...

wow thats looks nice! Something to shoot for with my Argento FR-S

Wow, serious misinformation I have had two cars a 2000 Celica lowered with TRD springs never had a problem with my shocks and struts and the same goes for my lowered TC with Eibachs after 8 years. Springs will work just fine for you unless you are doing auto cross all the time.

I have to agree that it's a risk.

I'm no expert but in any spring&damper system you're going to have unintended dynamic response if you change the spring rate (your spring) but not the damper (your shocks).

Your damping ratio will change, and as such so will the solution to the differential equation describing the dynamic response of your suspension system. If you change the damping ratio enough you could go from a situation where you're critically damped to under-damped (or over-damped). Not that one is better than the other but they each have their own behaviors and some are not desirable for racing conditions.

The caveat here is that you really can't know until you run the simulations but if you're just guessing it could lead to some unintended behavior.

My understanding is that you are likely decreasing the life of your shocks, even if slightly. Worth it? Definitely!

When you are shopping, look for a note from the manufacturer that states the springs were designed for use with OEM shocks. I've seen that on a couple of them.

That's why dealers void the warranty on the suspension

Save the money from the (IMO UGLY) 5 axis kit and get coils.

How does AutoX ware out springs?

And having a lowered car on stock struts will ware the struts out faster. It's a fact proven by science. Like many people have stated in 18 million threads on this forum having the stock struts out of their sweet spot will ware them faster. It's a principal that applies to any car.

TRD springs prob have such a mild drop the ware rate on the struts is not increased enough for you to find it unacceptable.

Awsome Rims! What size are those and name!
