Carbon Fiber weight reductions, is it worth it? Options

[dutchboy]

How much do each of the OEM style CF hood and hatch from Seibon / Vis shave from the weight of the car?

Are hood pins required for the hoods(has OEM style hood latch).

Be sure not to count the glass in weight measurements.


Just wondering if it is worth the cost of the parts.

Thanks!

hahahah...you know there is more to racing than a 1/4 mile.

removing a sunroof is a dual purpose...let me requote that for you
"removing upper weight (IE sunroof, hood, hatch) shifts the weight balance of the car to a LOWER point (thus giving lower center of gravity).
the more "upper" weight you can remove the better your car can handle."
its handling advantage.
lowering the center of gravity and cutting weight can cut LAP times down.
better handling & less mass = later braking points and faster corner speeds = faster laps.

please go to VIR/Summit hell even a drag strip and tell the real racers weight reduction is psycological

you have yet to make a valid arguement besides an unsupported claim of psychological factors. When you can techincally support and prove it come back and talk to me. I on the other hand can.

my weight savings > you

all the AC boxes came out, the sunroof came out (honeycomb/carbonfiber LTW plug replacement) not to mention many many other things

clearly i understand your argument and agree 100% with reducing weight=better times ESPICALLY on an auto cross track...but what im trying to say is how many people on this forum are going to completely gut there interior like you have??? not many...most are looking for a "quick and easy way out" such as replacing both the hood and hatch with CF ones....which is a great idea and again it does lower the center of gravity...im not arguing with you about that at all....what im saying is that by removing your sunroof and throwing a CF hood on your car is not going to drastically improve your times....yes it may cut lap times down a few tenths but all that for what? when you could do simple mods to your motor to get more out of it....
