Donkin' donuts !

At more than 150 large US $$$, the value proposition is all upended. The Caterham R600 at $100K is bad enough - the Donkevoort price is insane. I may yet supercharge my WCM S2K, in which case my car will possess much of the Donkevoorts' merits (less some appearance points and top speed due to poorer aero) at less than 1/5 of the Donkevoort cost. For the same meal money, I'll take my S2K as salad, a Rossion with 500 HP Duratec for the main course, and a 250 CC shifter kart for dessert!

Bruce,

 

I can't see anything about your car that loses appearance points to the Donk, none at all. I think the Donk is the least attractive of all the major clones of the Lotus 7.

 

Just my opinion and I'm sure there are others that think the Donk is beautiful.

I do enjoy the classic "Seven" lines of my WCM, although it needs some front downforce. I see you added front downforce to your Caterham, which incidentally is completely beautiful and must be a beast with turbo-power. My car makes about 250 HP with FI, so I have had it up around 120 MPH on a couple straights. I will be taking it next to Grattan Racetrack in Belding MI, which has a quarter-mile straight that you enter off a bender carrying good speed. There I may hit 140 or more, and I suspect I will not like the lightened steering.

The chin spoiler and whiskers raised the scary speed from 120 to 135 mph on my Caterham. At that speed it felt like a strong fart would put me off the track. I don't go there anymore, I hold the straight speeds to 125 or less and I do a lot less track days than in the past.

Skip,

 

With the chin spoiler and whiskers installed, is front end lift still an issue at 135?

I've not been nose-light at 120 or 125 mph - possibly my S2000 drivetrain is a little heavier than your 1.8 liter Mazda. Also, the WCM engine hood bulge likely adds a little downforce - you can see it in the pictures above. I may have another advantage that will keep the nose down at speed: minimal ground clearance - about 1.5" with the Black Diamond racing wheels. I may be able to handle more speed than I thought. With the two Caterhams that I've owned previously, 125 MPH felt like glide speed. My next track day at Grattan should be informative on this issue regarding the WCM.

 

Speaking of track days, here's the YouTube link to my last one at Waterford Raceway in Clarkston MI:

Yes. It wouldn't take much of a side wind to take the car off the track. They only reduce the front end lift already present. There is no down force. I think the car might do close to 150 mph if I could get the nose to stay down but I don't have large enough attachments to try it as it stands.

 

On a Lotus club trip earlier this year we ran at 100 - 120 mph for awhile on some really deserted back roads with gentle sweepers and the car felt well planted and controllable.
