One more like this or the post before it, and you're on a three-day vacation.

And the rest of you, the guy asked a serious question. Answer it politely, or don't post in the thread.

 

Why not just buy a race car?

 

The BMW M6 has a CF ROOF for weight reduction. That's a waste? That's rice?

People spend lots of money on light weight rims to help improve performance. OTher spend lots for 5-10whp. This is just another to add to the list. Maybe it's for you... maybe it's not. To each his/her own.

 

Well, I got an email back from DeftRacing. They are busy doing other custom work. I have two other emails out and am waiting their responce.

I have been thinking about the Aluminum suggestion. Certainly this would require significant understructure to provide rigidity. Would a simple puckered X on a spotwelded second piece of Aluminum be sufficent? I was studying the glass and there is also quite a bit of curve to it. I would think vacuum molding would be so much easier to reproduce this shape. Rolling aluminum to match would be quite a job.

I was tring to figure the best guess on weight savings with my new rims (still unmounted cause UPS couldn't get around to delivering the tires on Friday) The old potensas are listed at 27lbs and my new tires are 28 (tirerack numbers). But my wheels are 17lbs vs a likely number of 22lbs for the stockers. That is a conservative weight savings of 3-4lbs per wheel. I cant imagine getting $h!t for this. (besides the fact that I jumped to a 9.5 inch rim that will fit 275mm tires.) However saving 10-20 lbs up high on the car gets me comments like "you shoulda bought a race car." I find that behavior particularly amusing. A race car vs replacing my sunroof. hmmm.

Anyway, after lots of thought I am going to take this as far as I can go. If I drop a couple bills on it, itd be worth it. Names of custom aluminum and cf fab'ers is appretiated.

 

On the contrary, it makes significant difference. That's what they did to the EVO8 MR's roof, though u need a very skillful fat ***** to exploit the lower COG.

 

Just make sure you don't messed up the front rear weight distribution while you are shedding off your car. Imagine an 8 with around 1260kg... that's gonna be sweet.

 

CarbonRX8, please post the details of your solution. I would be really interested.

 

if you have money i would suggest getting your front doors in CF. Since you don't care much about stereo or speakers you don't have to worry about putting them in. Power house amuse in japan made a cf hood, doors, bumpers and other body pieces, seats, titanium exhaust intake, etc and were able to remove about 200lbs from the car...

 

Anyone else remember when only the American companies put heavy slabs of glass up in the roof? The Europeans always used a metal panel up there, hence "sunroof" vs. the American "moonroof."

But as with cupholders the American consumer won. As far as I know no one offer a metal sunroof anymore. Then again, we are living in the age of the 3000-pound compact.
