i would definetaly go with the trds over eibach, better spring, cheaper price. btw red, white, black... its called powdercoat, under the paint its the same spring.

 

from what this one dude told me
eibach makes the trd springs but just branded by trd
eibach has different springs and so does trd just eibach makes the springs for trd kit...not sure on the specifics on the lowering..as far as my knowledge..trd is 1" 1/4 and eibach is 1.4"
im confused myself as far as what to get
i want something easy and nice
i might rock trd full setup...struts and shocks

 

to my understanding Bilstein makes TRD springs... look it up

 

ive always heard that the trd's are eibachs like otherws have stated. I will never understand why some trd's sit level and others the rear is obviously lower? what gives? bad install?

 

I just Looked on eibachs site and they list the pro kit as 1.2/1.2 and then summit racing lists it as 1.4/1.4, kind of weird that its advertised differant depending where you look..oh and they also have a sway bar kit listed for the tc as well as part# 8284.320...kind of interesting as ive never seen any talk about it.

 

eibach does make the TRD springs they told me that when i called eibach. but they would not tell me if they were the same as the pro kit rates or not. they just said toyota will use some of eibachs springs and re badge as trd and they said they will also have a design from toyota and make it for them. all they would tell me was that pro kit for the tc is like 20-25%stiffer then stock and the sports were 30-35%stiffer.

 

Ahem.

 

if TRD springs and Eibach pro kit springs are the same why would you pay $50+ more for eibach when you could get TRD. seriously asking because I was thinking about getting Eibachs but if they are the same i'll go with TRD.

 

eibach hands down

 

Well since this old thread came back to life I might as well update! I went ahead and installed my Eibach's on the stock struts, and have put about 15k on them since with no problems. I'm happy with the stance and performance of the car so far! I also installed the TRD sway a couple of months after the springs and that made a huge improvement in the handling.I'm planning on getting some 18's in the spring, so I think it will look even better!

 

hmm i think eibach pro kit is the better choice in this one at least imo
