Springs arrived, great turnaround, everything arrived in great shape!

Just... now comes the 2-3 week wait for the TRD 86 Rally parts to arrive from Japan due to the the hastles of international post ATM before I wed the two together and get things bolted on. >_>;

If it's EMS the backlog is 4 months, at least that's the info that was posted. None of it has changed...

Might want to figure out a better way to send it. DHL/FedEx/UPS is more expensive but at least you are not waiting months.

DHL and comparable would've cost $400-600 for the few options the company had for shipping, around as much as the entire suspension did since the rally kit without the springs is only $530USD.

I opted for surface, which yeah might be 2 months, but usually in my experience is closer to 1 month or so. If the wait gets too unbearable I can still put the springs on the OEM parts and rotate things around when the rally kit shows up.

no worries.

if for some reason your order is cancelled let me know, I can get TRD Japan stuff as well via ocean, turnaround time is 45-60 days.

Thanks much, I'll definitely reach out if needed, I'm hoping these springs pair as well with these struts as it looks like they will.

Is there any interest in the TRD rally shocks? MS260-18004

I got some pricing back, realistically we are looking at around $650 USD plus shipping for each set.

Price is higher than Japanese MSRP but this is a landed price, FOB Chino 91710. If you were to buy it on your own from Japan, freight will probably add on another $200 or more if it's even shippable...

Edit: probably able to combine with Chuhatsu to do around $1000 each set of spring/shock. Not sure if there is a market for this in the US but at least the products are readily available. TRD springs look to be around $1100 as a package

But what are springrates of chuhatsu vs original rally shock springs? Are they close enough for shocks valving to match rates of chuhatsu springs? Also is diameter of springs same so that rest, like spring perches, are compatible & springs interchangeable?

The only question is regarding the spring rates of the TRD Springs. The shocks are sold separately and there is no indication that it needs to be paired up with a specific type of spring. Even the instruction manual in Japanese does not specify this information. Additionally, this spring and shock combo does not require you to purchase specific purchase or upper mounts to install, so OE equipment is reused.

Well as you copy-pasted later the "TRD Rally" springs are MUCH stiffer than OEM or these ones.

To put things in more readable perspective:

Code:
FRS BRZ TRD Chuhatsu
131 153 257 129 Front Spring (lbs/in)
211 195 291 206 Rear Spring (lbs/in)
    560 540     Front Compression
   1690 1250    Front Rebound
    735 400     Rear Compression
   1620 1120    Rear Rebound
The stock TRD springs are RIDICULOUSLY higher rates to end up lifting the car despite being shorter springs overall, but the problem as noted by one of the folks that installed the TRD kit was the springs are too short for full suspension travel. These springs are longer which avoids that concern.

Honestly laying out all the numbers like this makes me more excited, this may well turn my BRZ into a true 'grand cruiser' with the spring rates closer to the FRS but avoiding the 'riding on the bump stops' problem the twins sometimes experience, and with softer absorbers this should be very comfy.

This is coming from bicycles I admit, but less compression and rebound generally means a softer ride on harsh roads, both at the expense of some grip in various situations as the wheels don't hug as tightly. Since I'm running a wheel/tire combination 10 pounds/20% lighter than stock (205/55R16) I don't need the suspension to work as hard to hug the road.

This is months late I realize, since yeah shipping was hellish getting the TRD absorber set from Japan over to the US. Ended up getting here via literal courier to Hong Kong, from there into China Post and from THERE finally to the US.

Just literally picked up my BRZ from the shop and put it through it's paces, the best way I can describe the combination of TRD Rally absorbers + Chihatsu springs is "buttery smooth" and makes the ride a bit quieter as well as a lot easier to get in/out of the car shockingly.

I'll take some measurements later once it's settled out fully, but it's a well over an inch of additional height all around with that combo freshly installed.

If anyone spots this and wants to take theirs to an even better daily-driver setup, especially if you got one used so it has worn-out suspension right now, this combination is really, Really, REALLY good IMHO.

So I've driven this for another couple hundred miles now, had a chance to try a few places I know well.

Biggest change? The additional suspension travel and body roll feels like it lets the car properly 'squat and scoot' so it's noticeably harder to get traction control pissed off at me. I can WOT while turning up onto highway onramps and get all the way through 1st and 2nd without the tires being exceeded, and I'm not running anything remotely sticky.

Likewise while there's more 'body roll' it's way more controlled. If feels like there's time to actually 'catch' the roll and work with it, instead of getting tiny wiggles that suddenly upset things. Not sure if it's just the added split seconds of travel time, or the softer + progressive bumpstops from the Chihatsu springs doing it.

I haven't had a chance to experiment on gravel/dirt yet, that's tomorrow, the above is all asphalt. And again I'm running a straight-up 'foul weather' touring tire (Vredestein Quatrac 5, 205/55R16's), so before I could spin rubber in 2nd if I turned off TC and tried.

But I'll definitely say these springs and the added height make a huge difference on making the toyobaru more relaxed to drive. It's far less "over-caffeinated chihuahua of sports cars" now.
