nc7s4 Posted October 13, 2023 Share Posted October 13, 2023 Here is my wcm ultralite s2k just getting finished with it's new color and decals. Super excited about this car, we are planning to race it next year. The color is 3m pine green metallic if anyone is wondering. So far after getting this car over the summer I've changed the fuel lines to Teflon + new pump and filters, relocated all of that. Also the fuel cell needed a new bung welded on for the vent because it apparently was not vented other than some holes that were sealed up with rtv and have also since been welded shut. I added a newton fuel cell pressure blow off valve, between that and the Teflon lines our garage is fume free. Initially the car was emitting a lot of gasoline vapor while parked. I've changed all the fluids, added some new racetech mirrors, changed the clutch mc, reworked the pedal box a little, fixed a bit of wiring, changed the steering wheel to a smaller one for more legroom, and added a grille to the front. Next it gets a new muffler and completely rewired. Should be ready to rock after all that next spring/summer. Cars name was Goldie when it was built and I intend to keep the some gold around to maintain that history. Glad to have met some folks who previously drove the car in one lap of America. Just overall very excited about having it. 1 Link to comment Share on other sites More sharing options...
RGTorque Posted February 6 Share Posted February 6 I know a little about this car. I helped my buddy Garrett find her. I even have the supercharger kit, intercooler and all that was built and used on her. Somewhere I have (or had) the historical pics of her at some races and pics of the magazines she was in. Im sad to see the car has moved away as we often rode together but i know the car was getting limited usage and there were plenty of things that needed attention. http://farm3.static.flickr.com/2040/2469975174_7f91ddf937_m.jpg http://farm9.static.flickr.com/8058/8240524804_9e49f90af7_m.jpg http://farm9.static.flickr.com/8070/8240523914_13e71c56cf_m.jpg http://farm9.static.flickr.com/8483/8240522956_39288299a3_m.jpg http://farm9.static.flickr.com/8345/8239464219_8438116b94_m.jpg http://farm4.static.flickr.com/3263/2488629196_3dff1f2540_m.jpg 1 Link to comment Share on other sites More sharing options...
nc7s4 Posted February 6 Author Share Posted February 6 Hi Roman, thanks for the pictures. Could you give a rundown of what you thought was needed for the car? I am going over it and trying to get it race ready. It would be good to reconcile your list of things with what I am planning. Also - about the supercharger - I am surprised to know that it had one in it's past. The car seems unique that it has a crash structure on the sides. I am curious how it was used or anything you may know about it. It is presently living in the Detroit area which is not so far away and I hope to be active here on the forums as we get into it.

RGTorque Posted February 6 Share Posted February 6 I think the dash and wiring were in need of attention as well as possibly the heims? Its been a while since ive seen the car. Link to comment Share on other sites More sharing options...
nc7s4 Posted February 6 Author Share Posted February 6 It's getting all new wiring and an AEM digital dash. You are right the one it came with had been through a battle. Don't suppose that the supercharger kit is for sale? I might like having something on the shelf, when my driving skill calls for it. Link to comment Share on other sites More sharing options...
RGTorque Posted February 6 Share Posted February 6 i could sell it for sure. I always had plans for its use on my own car but its just not happening. Link to comment Share on other sites More sharing options...
nc7s4 Posted May 18 Author Share Posted May 18 Here are some pictures from yesterday of the car on track. What a monster! Took about a half day to get a feel for it. I think we will get along just fine! 2 Link to comment Share on other sites More sharing options...
Croc Posted May 18 Share Posted May 18 The green livery with side stripes suits it well! 1 Link to comment Share on other sites More sharing options...
vipergeek Posted May 19 Share Posted May 19 I had a Subaru SVX about that color. It was a nice car and I liked how it changed shades of green in different light. I also liked how it would go through two feet of unplowed snow in the mountains of Eastern Arizona one winter. 1 Link to comment Share on other sites More sharing options...

Cueball1 Posted June 23 Share Posted June 23 Curious about the wrap. Diy or professionally done? Interested in the cost. I'm looking at a wcm that's not exactly pretty. Wrap might be just the thing for it. Also curious if the mods suggested in Bruce's wcm guide have been done. The reinforcements, bump steer brackets, etc. Link to comment Share on other sites More sharing options...
nc7s4 Posted June 23 Author Share Posted June 23 (edited) Hello, yes I found a local business on google maps called elevated restyling in Livonia Michigan. They really did a great job all for $1600. They even made some decals for the car, stripes and added some fender protective film which has been holding up great. Diy wrap might be difficult especially with the nose piece. Regarding the manual, I've contributed a few of my own mods to it and borrowed several ideas from what is in there too. Biggest improvements by me are the electrical including an AEM display/logger that replaces all the standard gauges. Mirrors with 3d printed brackets, wheels and tires, oil pan, engine mounts, setup and corner balance, lighting, newton fuel tank vent valve to avoid fumes in the garage, steering wheel changed, pedal box was reworked including cables and links, fuel pump, filters and PTFE lines, exhaust all redone, upholstery was also redone including some modifications to the shifter lever and boot to make it nice.

Cueball1 Posted June 23 Share Posted June 23 Plenty of work you've accomplished! Well done. What tires did you go with? I purchased a Birkin 7 last fall which is a beautiful car inside and out. The wcm I'm looking at is definitely not the same fit and finish and certainly not pretty the way my birkin is. The s2k motor/tranny, additional cabin space and independent rear end are a big plus though. On rough roads the solid rear axle in the birkin is punishing. This affordable local wcm has me intrigued though I definitely don't need yet another car, let alone a second seven. I may buy it, drive both and sell off the losing car next spring.

nc7s4 Posted June 25 Author Share Posted June 25 From the factory the car has 225/17's front and 245/17 rears. I stuck with this staggered setup and am running Enki wheels. 8 inch front 9 inch back Tires are 225/40ZR-17 CONTINENTAL EXTREMECONTACT FORCE XL 245/40ZR-17 CONTINENTAL EXTREMECONTACT FORCE XL This is a newer option for the autocross-street style tires. Seems fine to me. My reasons for buying these was that they can take more heat cycles, and since the super 7 will never wear out the treads, heat cycling them out will end them. On track they are very quiet, no noise when cornering which is a little bit weird. Other cars are really screeching which seems to help figure out the limits of the car. Mine is very quiet, and ive looped it a couple times without much notice from tire noise. I have nothing to compare these to. But they seem fine to me???

nc7s4 Posted June 25 Author Share Posted June 25 (edited) One more thing to note is that the race setup is 15 inch wheels with 9.5" hoosiers all around. I do have the 15 inch wheels on hand, and required spacers, but at this point I see no reason to install them. Edited June 25 by nc7s4 Link to comment Share on other sites More sharing options...
Cueball1 Posted June 25 Share Posted June 25 I've been considering the Conti force for a street tire on my Birkin. Good to hear your impression of them! Lack of noise would be disconcerting to me on track. Must be our lighter cars. Lack of noise would be disconcerting to me on track. I'm used to "talkative" tires.
