TRD Lowering Springs?

Totally agree:rockon:.

 

Thanks. I was gonna installed eibach or TRD but its not drop enough, tein got issue with rubbing for my set (too low), so i got it in between....

 

If ur looking for a de decent drop the don't go with TRD

 

I did some research before deciding to go with the TRD springs myself.. Here's what I found..

Tein HTech Springs - 1.4" drop (front) and 1.5" drop (rear)

TRD Springs - 1.1" drop (front) and 1.3" drop (rear)

Eibach - 1.2" drop (front) and 0.8" drop (rear)

I went with 18" wheels, so the Tein HTech springs were a little too much (I thought), but the Eibach's were no enough.. So, went with the TRD instead.. I also wanted to stay away from rubbing, and figured I used Toyota parts as well..

 

Rickel, would you mind adding the spring rates in your post for future reference? The drop information is good but the spring rates will help people determine how tight or cushy a spring is.

 

Why don't you guys just cut your stock springs?

Jk don't.

 

ound:ound:

That's funny.

 

pictures please...

 

Look at the difference in front to rear drop between the TRD and the Eibachs.

 

I found that rather odd as well. If that is really the case then it really strengthens my appreciation for Eibach springs. I don't like the "level" look and the Eibachs seem to provide a little more of a rake (front end lower than the rear). Once I finally get around to it those are the springs I'll likely get.

 

I measured all four corners before and after my Eibachs. It is actually 1.0" in the front and 1.0" in the rear. I am sure there is some percentage of tolerance in the springs and car parameters. The balance front to rear is spot on...but cannot go any lower or it will rub (at least with my rims and tires). And I would not want to go up on the spring rate...quite stiff as it is.

 

I've got close to 1000 miles on my eibachs now and I have two of the exact same cars in the garage, the other is completely stock. My fronts are 1.25" lower in the front and my rears are 1.5" lower. But the fender gap is exactly the same. I do have a little bit more weight on the back with the curt hitch and bike rack, so i suspect that may be resulting in a slightly larger drop in back. But for sure it's no more than .25".

 

just picked up a set can't wait to have them installed!:cheer2:

 

I've asked this question before but it never really gets answered........why dont more people go with H&R springs?

 

Probably because it doesn't seem to get advertised as much.

 

H&R shows a spec drop of 1.3" front & 1.2" rear

Maybe that explains why some have asked why mine looks lower compared to Eibachs.

 

I had this(H&R) on order & nearly bought it but canceled last minute after I saw couple members here on Eibachs. Maybe, if I had seen some prius examples on H&R's I might have gone through with it as it's hard being the guinea pig.

 

how are the tanabe lowering springs ?

 

For those that are interested, here is some infor on spring rates OEM vs. Eibach.

SKU:TEN-SKQ08-G1B00 (30989)MSRP:$215.00


Tein is a well-known name when it comes to spring and coilover damper kit. Tein products are made in Japan with high-grade material for performance and quality.


Tein H Tech lowering spring provides approximately between 1.0 to 1.9 inch drop to achieve a balance between aggressive styling and comfortable ride experience. Check the detail specifications of each Tein H Tech spring set for your car for the exact height drop measurement (included below).

Most Tein H Tech spring sets feature rubber spring protector tube to dampen noise level. Tein H Tech springs are first coated with zinc phosphate, a rust-proof material. The H Tech springs are then finished with a long-lasting gold powder paint. In addition, each Tein H Tech spring is made using a new material called Vanadium (SAE9254V), a strong, lightweight material that retain more spring stroke for optimal quality.

Tein spring manufacturing is a multi-step process involving:
1. Cold-coiling to create the spring
2. Low temperature tempering treatment to eliminate residual stress
3. End-face grinding according to the form of each car application
4. Double shot peening to the spring surface to increase spring life
5. Setting at elevated temperature to minimize loss of spring load
6. Coating treatment to prevent rust.

Each Tein H Tech lowering spring set comes with 4 springs, 2 for the front and 2 for the rear. Each Tein H Tech lowering spring set comes with a 1 year limited warranty.
