Hi, what's the weight of that entire floorpan pls, just out of interest?

[Cookies220]

Love it. Must reduce undertray rattle too!

Have you seem how much reverie charge!

[JohnTurbo]

You obviously never weigh your faeces. ...mine average beteen 1.2 and 2.4kg. ;-) Nice work matt!

As a slight "aside" I still think running without a rear floopan whatsoever is the way ahead. I've been doing this for 2 or 3 years now and I can't say I notice any difference in handling/aero. The benefits of not having a floorpan are much better cooling for the engine and gearbox, not to mention 6 Kg less weight in the rear of the car.

Oooh not a fan of that!

Plus, you don't have to remove it every time there's some minor maintenance required or you've dropped a washer.

I like mine though.

It's not that I'm not a fan of Matt's floorpan. He's a very creative and capable chap, it's more to do with whether the function of any floorpan outweighs the function of not having a floor pan.

According to reverie a correctly shaped under tray has a bigger effect on lift than most rear wings! Don't think the originals are wide enough though.

[techieboy]

Yep, free downforce (or lift reduction) as well, as there's no drag from it.

Premise: Reverie's existence depends on saying such things and getting people to buy into it.

I am not saying that a floorpan designed in conjunction with lots of other body changes can't help with aero/downforce, far from it. It's just that I think the VX220 has never had that sort of consolidated input. For a start a VXT has a CD of 0.41 - that is truly shocking, and shows that the designers made little/no attempt to consider aero. Taking the floorpan off the car might possibly (at a guess) add 0.01 CD to that. So you have to consider whether that is offset by improved cooling and weight loss...

So is the justification for a mod now that it saves the weight of a poo?

This can only lead to constipated VX'ers modding rather than laxativ-ating.

TBH, I was just having a play with new materials (new to me that is).

OE weighed just over 4kg on the better halfs scales (4.2), mine weighs just under 3 kg (2.9). I cant claim any accuracy of the scales but mass difference should be OK hence claiming 1kg saving.

Yes that!
