TRD Sports Springs (info with before/after photos)
There hasn't been much information posted about TRD lowering springs for the 3IS, so I decided to take a chance and try them out. I wasn't able to find any information online regarding the advertised drop or spring rates (I even tried searching through Japanese websites/forums), but I figured if they were developed and tested by the manufacturer they should strike a good balance between performance and comfort, while providing a mild drop to reduce the wheel gap.
The packaging came with TRD labeled springs, new bump stops for the fronts, and an information sheet in Japanese. The information sheet states that the front and rear springs both will "change the car height by about 10mm" (just over 3/8" or 0.393 inches).
PHOTOS WITH TRD SPRINGS:
COMPARISON PHOTOS (Left - Stock, Right - TRD):
The actual ride height changes are as follows (measured after allowing >2 weeks to settle):
IMPRESSIONS:
Drop: Very mild - fronts are close to advertised at 0.2-0.4 inch drop, rears are more than advertised at 0.8-0.9 inch drop. I would have preferred a more even drop, but it does make a significant reduction visually in the wheel gaps, and is an improvement over stock.
Performance: Good - noticeable improvement in both Normal & Sport+ modes, with less body roll and dive.
Comfort: Good - close to stock most of the time, but more noticeable transferance of imperfections when going over uneven roads.
Value: Poor - over 1.5-2 times the price of most other springs available. Do I regret the purchase? No. Would I recommend others to get it? No, unless you must have OEM parts and are willing to pay a premium.

Thanks for the review. I have the RS-R Half Downs and I would say the front drop on mine is noticeably more than what you have with TRD springs. Not so much in the rear but definitely in the front. I would rate the performance and comfort as similar. I notice my springs more when there are road imperfections or expansion joints but can't tell the difference from stock on most roads.

No Aftermarket parts void your warranty. Look up Magnusson-Moss Warranty act. Having said that if lexus can prove the aftermarket part was the direct cause of another problem (for example if an aftermarket coil spring causes you to blow a shock) you are liable to pay for it. Lets be clear as long as you aren't messing with the ecu and something breaks you can return the car to stock and take it back to the dealership without them knowing or having any proof that you ever installed aftermarket parts.

I'm looking for springs just to reduce wheel gap and would pay the premium for OE parts but the drop numbers u posted worry me. The back is double the drop, is the car dragging ***? It's hard to see the drop pictures because of the white. Think you could post some close ups clearly showing the tire and fender?

Great review, information and pictures. It was very useful on helping to decide what lowering springs to go with. I might go with the Eibach or Tanabe springs...but there will need to be more reviews of those too. Thanks again!
