Wow, thanks Erik, that's quite a change!!!!
Saturday arrived, and RobinJI came over to say hello, it was quite nice for a change having some help whilst working on the car, and some input to the creation too. Robin as we know is pretty clued up on all thing aero, which is pretty handy at times
I was keen to make sure that where the skirts joined the sills, there was no obvious join is unslightly seam line visible.
It worked out pretty well, that I was able to remove the side trims and grind them back 1-2mm on the back face, to create a slot underneath to tuck the skirt behind.
At the door opening, I was worried it'd still be very obvious with the door open.
We decided to experiment on a spare offcut, and thinned the top edge right down to about 1mm thick:
This slotted in really well and seemed to work nicely, even looking like a proper fit at the transition from door to quarter panel:
Having already taken a few measurements, we knew that the 150mm deep fascia board was going to be too deep. I thought I’d take the chance to chamfer the whole top edge at full height for a test fit though.
I trimmed the top edge right down, and test fitted it:
This worked well
Deep skirts would be more effective in terms of air flow, although they run the risk of potentially looking like a silly ‘hovercraft’ style drift kit, which I was keen to avoid.
With the theory proved, we did some measuring relative to various points on the floorpan, and decided to cut 30mm off the boards to give me a sensible depth skirt for this V1.
These were cut down, and the taper restored to the top edge, then test fitted:
To secure them, as per my sketch a few weeks ago, we made up some ali brackets to mount to the sills:
Which sit something like this:
Last up was a small cut out at the front of each skirt.
Reasons for this were 2 fold: partly to allow jacking access to the chassis rail, and partly to make some attempt at allowing wheel arch pressure to escape behind the wheel. At this point the skirt actually sits higher than the sill line, so hopefully it won’t be trapping too much hot air from the front arches in.
At this point, it rained like hell, and it was getting late, so we gave up for the day. Tori ****** dinner, and we chatted rubbish about cars late into the night over a few beers
