J Red: "While there may have been a set of
springs that only dropped 1", I don't believe that TRD sells
them now. The only spring available in the US from the dealer
is the 1" advertised spring (P/N: 48130-AW100) which dropped
both of my cars approximately 2.25F/1.75R. BryanH got similar
results from the same spring set.
I have never seen any other spring set, other than the Gymkhana
and Rally spring sets in an old TRD catalog. These aren't "lowering
springs. I would feel confident telling you that if you order
the TRD set from your dealer or Fensport, etc., that you will
get the spring set you're after.
The part number on the springs is different than the set. Both
can be verified here:
http://www.toyota-trd.com/en/strt/s_lowsprng.html
The front is 48131-AW110
The rear is 48231-AW110
Those numbers should be painted onto the springs themselves.
If the numbers match, and you either shorten or replace the front
bump stop with a shorter one, you should be there."
J Red: "TRD USA's part number 00602-48130-003 is the Toyota
Technocraft Japan, Ltd.'s number 48130-AW100 which has been in
place since 1997, and perhaps earlier. Hence, they are "TRD
Japan" springs.
Those springs list rates of 2.9/5.0 kg/mm F/R on this page of
the TRD Japan website, and show a drop of 1.0 F/R, in the 1997
TRD All Parts Catalog. In my experience, they drop the car lower
than that..."
BryanH: "My TRD set was purchased new in February 2003 direct
from TRD. They lowered the car a lot. Others have put TRD springs
in and not gotten much lowering - I'm not sure why. But mine really
slammed the car - I had zero fender gap up front. It looked great,
and rode pretty smoothly. The spring rates were a good compromise
for street driving and weekend racing. But the springs were just
too low for their own good. I constantly scraped over speedbumps,
the front outside tire would rub the fender during a U-turn (even
though my tires were smaller in diameter than stock ones!), and
I had insufficient suspension travel up front, which created resolute
understeer on the track."
