uhm.. sorry infinite, but you sound pretty damn ignorant.

 

haha ignorant to what degree? Look its my opinion and thats just how i feel. So what if you shave 30 to 45 pounds off your car. Either way our cars are still going to be pretty heavy. Does it save gas? Yea a couple miles whoppy doo. Reduce body roll?? Yea maybe but what are you going to do, take it autocrossing? Its still fwd. My point is that its a waste of money to rid the sunroof. You might as well have bought the spec tC. With the money you spend on replacing the sunroof..you could have bought a sway bar. I think Toyota knew what they were doing when they put certain stuff in certain places of a car. Maybe that heavy sunroof was placed there to perfectly balance out the car.

 

uhh.. no idea why you'd think the spec would be any better... sure you don't have some mechanical parts moving a glass moonroof..

but one large piece of solid glass?? i think would make absolutely no difference in weight or if so, completely negligible..

 

dude, take a look at the OP. he clearly asks if it'll reduce body roll. will replacing the roof with something 30 lbs lighter help? absolutely to a certain degree. center of gravity will move down giving the car a more stable feel. will he go autocrossing? who knows, but he did ask something that had to do with handling, making me confused as to why you brought up the issue of 300 hp. but, i do agree wtih you, a sway bar will definitely help, hence why i have one also. but, the spec glass is pretty ideal for autocrossing because there's no motor, no heavier reinforcements that the regular sunroofs have. i have a friend who had picked up both roofs, and he said that the spec roof weighed significantly less.

 

I agree brother but he also asked if it was a waste of money. I believe yes..even though that might be a good path to shed some weight and reduce body roll...there are so many other things he could do instead of wasting his money on this. Might as well go on a strict diet plan with his car and strip everything heavy in his car. Thats if he was serious about reducing body roll. Sways are enough.

 

I believe my Spec roof has the same bracing, just no motor/electronics.

The best place to remove weight would be from the highest point of the car.

Estimates I've read say -100lbs is worth the equivalent of 10hp

 

and 45 is no where near 100

 

Totally random but that glass sunroof is indestructible lol...in the event of a rollover your head WILL be protected.

 

.... it's glass... it breaks.

 

NORMAL glass does. Check this out. Some guy by the name of Bloch wrote this...


Scion tC is One of Eight Vehicles to Meet Proposed Roof Crush Standard
posted in Scion tC News |
Bloch said that the auto companies know how to make safe roofs, but only eight vehicles currently on the road meet his proposed standard of a strength to weight ratio of four to one or more.

According to Bloch, those vehicles are: The 2006 Volkswagen Jetta has an SWR (5.1 to one), the 2007 Toyota Scion tC SWR (4.6 to one), the 2006 Volvo XC 90 (4.6 to one), the 2006 Honda Civic (4.5 to one), the 2007 Toyota Tacoma pickup truck (4.4 to one) the 2006 Mazda 5 (4.4 to one), the 2007 Toyota Camry (4.3 to one), and the 2007 Toyota Yaris – it’s a small inexpensive car – (4.0 to one).

“So, there are only eight cars with strength to weight ratios of four or better,” Bloch said.

“And one is a small inexpensive automobile. And yet, if you look at the Dodge Ram pickup truck and the Ford F250 pick-up truck, their strength to weight ratio is 1.7 to one.”

Long freakin story short...that glass is there for a reason.

 

has anyone removed the motor/track/bracing/and ALL the roof glass? im pretty sure its alot more than 35lbs.more like 100+ and if your going to do something like this you might as well go all out,or it wont be worth it.that said removing 100lbs from the roof will make a huge difference in how the car handles.

 

Sorry for the misunderstanding, I wasnt implying this mod was worth -100lbs, it's an estimate value for the value of weight loss.
Lost in translation-- optimistically, this mod would be equivalent to something that adds 5hp.

 

dude just take ur backseats and spare out.

 

decreasing wait will NEVER=more HP.
thats a common misconception.
it increases the power to weight ratio.

 

^of course, it is actually power to weight, thanks for the clarification, yellowxhoodie.

 

17lbs is approx the equivalent to 1hp.

But the point that people seem to be missing, is the location of this weight. It's sitting directly on top of the car, the worst possible place to have weight. 50lbs is a lot of weight when it's completely out of place.

The glass isn't what makes the tC a great roll over car, it's the structure of the frame. Look at every single roll over incident of a tC. The entire roof is gone.

 

^^agreed

 

ive been seriously debating buying this over the winter.
well see what happens.

 

Frame still intact. Glass completely gone.

 

anyone replaced the entire glass roof? any links? any manufacturers? ive googled it in everyway i could imagine and found nothing.
