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:

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.

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!

[/b] thanks, roman. here's a few more stills from the Waterford track day. Note young female pit crew - very helpful, and only cost me about 2 Reese's and one Coke for every wrench they handed me:

here are some stills from the Waterford track day:

hi, lorren. charlie from autoeurope's super seven sense was right on - the alignment gave me neutral handling, with just a tick of oversteer at the limit, which can be modulated with the throttle, a wrist flick or both. i have made mistakes, like hitting the "dragon's teeth" (like gator's teeth, but with cutouts) and a small pothole that lies just off the track pavement. I'm talking speeds of 80 to 100 mph, with some cornering force included. the car just skitches a couple inches and then settles right down. i have tried to compare this car to the other caterhams and loti i have owned and driven. the s2k roll center is lower than my supercharged lotus exige, and i can really feel that - the s2k handles better, plus it never pushes, which was how the exige dealt with corners it didn't like. my caterhams both had dedion rears. they were both fast and neutral, but the s2k feels better-planted, and is easier to control if overdriven. i'm super glad you responded, for another reason - on the waterford track day, i broke the hat that is bolted to the brake disc (fits over the studs, between the wheel and the upright). it is a wilwood part. from the passenger rear. the disc is exactly 12" and looks fine, but the top of the hat is broken all the way around. the hat flange is 7 1/2". the calipers are 2-pot wilwoods. the stud pattern is 5 x 100 mm. the hat is bolted to the brake disc with 8 bolts. there is a stamping in the hat: "KN3755". what are my wilwood part numbers? also could use any other parts that you can provide, for inclusion in the manual. thanks!

About time for a fresh WCM S2K Ultralite Super Seven trackday video! This brutal drive was recorded on Sunday 8/30/2014 at Waterford Raceway in Clarkston MI. The track is a short 1.5 miles including 9 turns. The run group was "Advanced" and included licensed SCCA/NASA pilots, experienced OTD drivers and track instructors. This group liked blue flags about as much as Snow White liked naps!

I have been assembling a WCM Ultralite manual since i purchased my S2K about 2 years ago. The project began as a convenience for myself and my mechanics, but has grown to include many repair experiences from many owners. We are up to about 100 pages now and NEW is table of contents, supercharger section, oil accumulator section, anti-surge fuel tank section and more. MANY pix including many rear hub assemblies. If you would like a copy, please respond with email address. i will send a PDF file, which you can convert to Word if you prefer. Take care!

i've been surprised by storkers at my home on several occasions. showed up in the middle of the night each time. left a shrieking bundle of milk-suckling, poo-spouting baby each and every instance. i'm through with storkers!

i don't remember any info in the manual on the pedal adjustment area cover. will have to look for that. it may be in the section submitted by captain obvious. converting the manual to pdf is quick and easy, and reduces the file size by about 85%. pdf is also a de facto universal format, unlike various zip programs which sometimes have difficulty unpacking data zipped up in other formats. while emailing around 17 manuals so far, i've only suffered one rejection due to excessive file size, so overall this is a small problem easily resolved by conversion to pdf format.

need your email address, jason. already about 15 manuals out, and only about 80+ S2K's in existence! if we keep getting contributions, this manual will be awesome by the end of summer.

wiki will be neat. i think the manual needs more development before it is released to wiki. examples: some additional basic structure including table of contents, some additional editing of the various forum posts which constitute many of the chapters, and inclusion of promised new material from other owners. there's already a powerful lot of info in the manual, but the overall product is still too rough-edged. another few months of work, then i will make my first wiki post! till then, just follow the instrux at the top of this post to obtain a copy of the manual-in-progress (70 pgs as of today). cheers!

thanks, lorren. lots of different contributors. manual is now up to about 70 pages. evilromeo, though each s2k is unique and bespoke, they are also a lot like human beings - individuals, but each more alike than different. trans tunnel repair, differential cross bracing, anti-surge fuel tanks, oil accumulators, upgrading heim joints and links - these and many other issues are common to all 80+ extant s2k's. there is also a developing "general info and history" section that makes good perusing, with lots of great pix. lorren - it's time you built a few more! you have a website, soon you will have a workable manual - now go and get some more customers!!

got the carbon fiber and adhesives, but haven't committed the time yet. i'm installing a moroso oil accumulator and a one-gallon anti-surge fuel cell this winter, so my plate is full. i agree re: circuit breakers. just the really purposeful stuff belongs on the dash, like tach and other instruments, paddock key, ignition. the rest should be behind-the-scenes, tucked away.

now that i look a second time, i'm also going to recommend a carbon fiber dash. that would update and upgrade the interior substantially. be sure to center-mount the tach, with shiftlights just above (shiftlights will get a workout - with a 4.11 or 4.44 final drive ratio, your first three gears will require ABOUT 1.7 SECS EACH!). and don't forget a detachable steering wheel. lorren now recommends moving the wheel up over the bottom dash crossbrace, but i'm not sure about that position. as long as the wheel is detachable (for ingress/egress), i prefer the undermount position for driving.

i agree with everyone - great upside. reminds me of a topless rolf, or maybe an older "C" or "D" sports racer. caterham produced an earlier car with full fenders, all aluminum, but a bit heavy and too cramped - never caught on. this car is way more aero than that caterham fender car - prettier, too. be nice if you can fair in the headlamps. use modern HID's, too - no old chrysler omni eyeballs for this bad boy!

fantastic work on that westfield. one could guess your aeronautic background after perusing the precise rivet alignments, perfect bends in the brake lines and so on. another thing i've noticed about you mile high guys: you think not only analytically, but sequentially (for example, the handbrake issue). must come from all the checkoffs you guys perform before every wheels-up. but one point of disagreement regarding that "adequate" total of 144 mazda bhp in your featherweight seven: it will not be enough. it will never be enough. this point will be corroborated by everyone. challenge me. you will see.
