Cost ~$10 compared to $200 for real TRD
Did gain a 1lb of weight though but should at least block all the grime from getting into the trunk lid area and stop air from going into the trunk area

It looks perfect! Need more info on what you used.

Don't forget don't your dust pan, it's sitting on your parcel shelf...

Have you driven it with the under body panels? I was going to do the exact same thing but I thought the exhaust would melt it almost immediately.

Ive driven it in 2 half hour sessions Nothing has melted so far. I need a good hour long drive im expecting the areas right up against the exhaust piping to melt but not much more.

Last year I did a test piece with coroplast in the tunnel area. similar to the pieces Velox sells. Nothing melted

Just took some quick snaps yesterday. Ill admit to not being good at the whole picture taking thing but you get the idea

Yes their roof will be the final piece. Finding someplace to come out and remove/reinstall both windsheilds is where im at with that. Im hoping Safelight or similar can do it for a reasonable fee

:O Fitment looks great on all the pieces. I'm all about a light car & I think you persuaded me on the doors

Awesome pics...


What would be really great with a weight loss build is some sort of performance data just to get an idea. Do you plan on doing 0-60 or any 1/4 mile runs with one of those Dragy GPS things?


I do understand that straight-line performance is not the purpose of the car or even this build, but just to get an idea. Before/after track times at a local circuit would be great, too.



Were you able to get any data before the build?



Awesome update

Prior to the pics the day before I took off the fenders and readjusted everything to fit better. Glad you noticed!

Sorry no official numbers. Only time its been on a track was HPDE events. Plus I don't really want to hard launch the car to get good #'s and fk up the clutch. And I don't have a good backroad around here to set up/ repeat without other drivers getting in the way.

But I did get curious about the effects and went looking for a good weight @ HP calculator just for an idea. Obviously there is way more to #'s like gearing ect. But for a baseline idea of acceleration effects.

I used this calculator
https://robrobinette.com/et.htm

Putting in weight 2774/ FLywheel HP 205 you get 1/4 mile at 14.6. I think most stock verified times are closer to 14.8. https://www.caranddriver.com/reviews...tested-review/

Entering weight 2350/ Flywheel HP 205 you get 13.8 in the 1/4. A difference of .8 secs. I don't think it would be that much maybe closer to .4

Then I put in 2350lbs/Flywheel HP 225 (estimating my power mods) and got 13.4 in the 1/4.

Not saying my car would run that all but could be able to get into the high 13's.

Good read. I only read up to page 12 (new to old) and maybe missed it, but you have looked into Radium Engineer ECU bracket? It may shave few oz than stock steel bracket.


Max Orido's rear diffuser might be lil bit lighter than Verus Engineer and it's designed for kouki bumper, so sadly zenki owner like me can't use it... but you can


of course, 326Power ver looks small and prob lighter, but feels like not as functional as Max Orido one.


For interior, TRD JP finally released some cf good. Door cover weight 1.2kg each (2.6lbs)



...but spending $4,400 just for door covers is hard pill to swallow. There's alumium door cover from Spnywoosh. I've heard some of older ver doesn't fit well, but cost only $220 isn't bad and shave 4lbs-ish total.


Now... if someone can make a copy of 14R aero kit. Cuz front bumper & wider fender costing total of $15k! lol


Anyways, keep up the good work!

Light, looks good, inexpensive...pick two haha
