how much weight do you save by converting to a spoon mooncraft on mugen cf roof?

like nothing. If anything it actually adds weight.


Mind you , this is what ive HEARD. The standard s2000 hood is very light.

I don't think that there would be a huge weight saving. The aerodynamics would surely help if you were tracking the car though. But I am not sure how much the Spoon or Mugen CF roof weight. Drycarbon is a different story though... :)

From what I was reading a while ago the whole retractable roof mechanism weighs just under 45kgs (99lbs) The CR S2000 with it's all alluminium hard top weighs 21kgs (48lbs) so in this case there is still a reasonable weight saving whilst adding to the aerodynamics.

The ROOF the ROOF the ROOF is on FIRE! Not the hood :P

Your questions comes with 2 variables.

Do you intend to keep the soft top installed?
Or are you going to remove it?

are you able to run the soft top while a hard top is fitted? thought you had to remove the soft top. im liking the look of the spoon mooncraft for the aerodynamic benifits at the track =]

You can keep the soft top if you want - doesn't matter either way...

oh i see. i know its a track car but after looking at interior pics of the spoon s2k from the uk, it had the roof removed and thought that this was the only way to fit hardtop

Obviously, you don't save any weight if you add a hardtop without removing the softtop. The softtop with frame and motors is fairly light at about 30 kilos (it's the frame that weighs the most). The Mugen CF hardtop weighs about 15 kilos, so you'll save about 15 kilos if you install the Mugen CF hardtop and remove the softtop. As far as any aerodynamic advantage goes, it's negligible compared to the gains from the weight-loss, although I'd expect there to be small aero gains if you spend a reasonable amount of time over 150kph. You may see more hardtops at the track as regulations for some categories and events require the use of a hardtop for roadsters.
