EVO magazine tweeted this today. It's supposed to be a CAD image of the mk4. The front bumper looks hideous IMO.

Didn't really know where to put this because there's no electronics section so I ended up putting it here. I noticed a strange behavior from my 197 on the highway today. Every time I use the right turn signal the cruise control gets disabled. It's as if I have pressed the O button on the...

Looks great! Really like the subtle look of the Maxton splitter and skirts. The only detail I dislike is the logo on the splitter.

Right. I've started doing simulations on custom parts, first one being a simple splitter. The picture below shows how it looks. It's basically a flat piece, 15 mm thick, that starts just below the rubber lip of the bumper so it makes the front lower by 15 mm. It extends 80 mm forward from the...

@peter @Gordini 18's offer stiffer side walls for better turn in and steering feel at the expense of acceleration and braking performance. It is a tradeoff I'm willing to make as I think it will give me more confidence to push the car in curves where Clios really shine. Whatever is faster on...

They are too expensive for most of us mate. Besides, mounting 4k EUR worth of wheels on a 10k EUR worth of car is pure insanity. Oh, ok. I thought they only supply them in white or gold because they only show those two colors on their website. There's also a dealer here in Sweden that sells...

@peter Damn, their Forged 1 wheel is droolworthy! 950 EUR a pop though! @Gordini Those are the Fullrace A right? They do look good and are not that expensive although I'll have to powdercoat them if I get 'em. Did you notice any changes in the behaviour of the car when you fitted them? ET56...

Those look pretty good actually but if I decide to get them I will have to order them from the UK or somewhere else because as it turns out, no one here (Sweden) sells them. :disappointed: I wouldn't fit the K-tec ones if they were given to me for free tbh...

That is an option, yes, but ideally I'd like to run 18's.

I'll be buying a dedicated trackday wheels soon-ish and I've been researching available wheel options for my 197. The result thus far has been me getting pissed at the wheel offset Renault chose for these things because most wheels don't go higher than et50. Alleggerita and the Ultraleggera are...

No idea mate. I'd guess not but I can test it.

Downforce, not lift reduction. And yes, the DF values are optimistic. Like I wrote earlier, simulations of this kind overestimate the coefficient of lift. Now according to PhD studies I have, regular hatchbacks and wagons are closer to neutral (zero lift) compared to sedans, and they can easily...

So I got a 2Gb RAM module from a friend that no longer needed it and decided to run everything again, with slightly increased accuracy. The numbers came out slightly different but as you can see from the table below but the plots are virtually unchanged so I wont be posting new ones. I also did...

Seriously. I wonder how much it cost them. Driving around Monaco in between F1 sessions can't be cheap. Either take the camo off and reveal it fully or wait until you can FFS.

Alrighty, the simulation on the Maxton stuff is finished. It has a smaller impact than both the Cup and the Sprint parts with a 7% increase in air resistance and 22% increase in downforce. What it has going for it is that it is the most balanced, with almost 50/50 downforce distribution between...

Yes, there is a gap between the edge of the bodywork and the spoiler but since I do not actually have these things laying around and modell from pictures, I cannot guarantee the accuracy of the size of the gap. Increasing the size should make the thing act more as a wing and less as a spoiler...

Stock ride height for now. I do plan on doing som runs on lowered/raked models though so stay tuned. The side skirts don't do anything and I don't need CFD to tell me that!

Sorry mate, my bad! Yeah, the splitter should affect things so I ran a simulation on the Cup spoiler without the splitter to see how much of a difference it does make. Turns out it doesn't do much. So while the spoiler is functional, the splitter is all show and no go, at least according to...

Damn it. You can disregard the Sprint spoiler results for now. I'll have to run it again as I've used an older model with slightly different front bumper.

The simulation on the Sprint spoiler just got completed. It's effects are similar to those of the Cup pack but with lesser magnitude. It increases the drag by 12,3 percent and the lift by 31,1 percent so the improvement of the lift to drag ratio ends up being 16,5 percent. Notice that I've...
