Just remove the hatch completely and cover it with plastic sheeting, more weight reduction for less money.

Goodbye airflow/aerodynamics.

Nah... Just do it so that it's taught, and makes a nice surface. It'd be like a tonneau cover, sorta.

It's actually not as crazy expensive as I thought for a CF hatch as I've found them for $700 (I was fully expecting over a grand). I've also been experimenting at work with different clear coatings for lexan as I know it can get scratched up. However considering it's on the hatch it probably wouldn't be terrible and your biggest issue would be it fogging up. If you coupled that with the CF hatch you're looking at dropping about 40 pounds. The lexan itself to cover that kind or area isn't that expensive either it'd run around $60.

Once you've done all the "free weight savings" this is probably the most cost effective weight savings you'll find.

Getting lightweight wheels will give you more get-up-and-go than this, but 40 pounds for around $750 bucks isn't bad at all.



Unless you want to do this.... lol

I got the CF hatch in a deal and a spare stock hatch (for the glass) from mkernz.
I might put the cf hatch on one of the cars and still have the stock hatch to replace if I sell it.

As for weight reductions, I know my hatch struts are gonna work fantastic now.
I really don't care about the weight or lack of weight with it. I'm happy that it's lighter than stock and is neato to look at, also, I would rather put on a cf hatch than remove...my moonroof, spare tire, hatch cover, seats, power steering, airbag, door panels, speakers, floormatts, and headlights.

I'm not making track cars, I have daily drivers.

Totally understand.. I'm going for the complete other end of the spectrum.

Before I picked up Shannon's car there was a really nice 2000 BMW 328i I was looking at, (owner didn't mention it was auto till I got there) and my wife said something about driving her friends around in it. I go "In what? You watch how fast I'll turn a sedan into a one seater..."

just increase horsepower and keep the luxuries.... lol

98-99 Celica SS3 with Superstrut has thicker axles which weigh a pound heavier per side.

Full beams air intake system weighs 7.4lbs

updated. was bored n weighed more parts n added to list above...

was thinking about making a the power steering bracket (2 pounds 5 oz) and 3SGTE/3SGE idler pulley bracket (3 pounds 14 oz) out of 6061 alloy. My guess is I could get the weight down by half but the price would just be too much unless 100 were made. was looking into an all alloy power steering pumps. however all the newer toyota ones are the style that are bolted directly to the block and use one large belt (such as that on the 1zz and 2azfe engines)

You could save a lot of weight by eliminating power steering altogether!

ya but then converting to ehps from mr-s is expensive as well. no way around that. you can yaris electric assist steering but then need to change your rack....
