WOW ! That is interesting !
Saw a complete article on this car in one of the Race Engineering magazines a few months ago. They make nearly everything themselves including shocks, steering, brakes that normally they would have to out source.
Suspension is mirror image, uprights as well. Frame is square tube and all computer cut. Pretty light but seems very stout. The magazine was very impressed with the package which is somewhat surprising having read other things they publish.

That cuts down on the amount of spares needed in the trailer...
Looks like a Shriner's car on steroids

Looks tiny ! Itty-bitty ! Says I who rides in an old Reynard on track days with tin tops.... Looks like fun !!!

There are a lot of passenger-car parts in the suspension, mostly to reduce cost of both parts and development, and to improve durability.
The body is made in 20 pieces to reduce the cost of each, and to make it so that a frame is the only part of the car that cannot be shipped by USPS, UPS, or FedEx.
It has a 1000cc engine and a 6-speed sequential - if those sound familiar, it's because that's a minimally modified motorcycle powerplant.
Total weight is just north of 900# depending on options. It fits into the NASA ST1 class - and while it was meant for racing schools and single make series, during development it was found to set laptimes that were faster than most cars in that class.
Plate-and-ramp-type limited slip, chain driven.
It will accommodate drivers up to 6'5" if your legs are long.
It's impressive to be able to hit that kind of weight while still sharing some passcar parts... smaller footprint doesn't hurt. But also to hit that weight at that price equally impressive.
If they can hit the volume and still make a profit at that price, we should be seeing a lot of these at track days!
I found the article on this car, it's in the March 2020 Racecar Engineering magazine. Interesting they made their own shocks, double adjustable, gas filled and use the same ones front and rear. Built their own diff as well with Mitsubishi Evo components. They buy the tubing at a mill quantity which saves a fortune and it's all premachined by them with tongue and groove ends to make jigging up very fast and easy. They sell replacement chassis for $3000. Weight of 900 lbs and 145 HP probably gives it pretty good performance. All body work designed to be able to simply UPS shipped. Their regular business gives them access to all of the various CNC equipment , multi axis machines, etc. I wish them luck as this could be a very reasonable cost way to go racing. Also has paddle shifting developed in house for the gearbox.Motor is a Suzuki GSX-S 1000 cc with standard gearbox. This motor is from a touring bike and has a bigger sump eliminating the need for a dry sump setup.
I'm not seeing any production car suspension pieces in there...

may be all 3d printed to save costs??
I talked to this guy at the PRI show and I was very interested. There's a ton of room for the driver. I had a guy with me that was 6ft 3in and 280 Lbs. He didn't have a problem fitting in it. Its a full size seat with a ton of foot room. The motor is a sealed GS1000 motor. Its the same thing as a GSXR 1000 but a different head. Open dif and large brakes. I'm a fan, but like everyone else I wanted to set back and see what challenges they face in their first year. Every body part is less than 250.00 so that makes it appealing by itself.
Great approach. I like the Aero work they've done on body shaping, and clever manufacturing approach too.
BUT, I gotta say - its looks a little "GOOFY." Like a fugitive from a Pixar film? Not "cute" - just odd and not sexy.
Hey - just my opinion. Maybe like a bad haircut when you are in it - you can't see it without a mirror or photo.

Everyone is going to have a preference but I would agree with you. A bit “over designed” in my opinion. Very cool nonetheless. Good luck to them.Quote:

Maybe we should hire those guys to write the rules for the next attempt at a formula car class......They seem to actually understand the economics.
Where to step to get in?
What is the wheelbase of this little car?
Maybe take the already developed components, drivetrain etc and further develop a "proper sized and shaped" race car.
The economy of scale is already halfway there! Even if it cost an extra $10,000 - $15,000....
Would be a k.a. solo car...
And you can spend more....

Looks like a C8.
I don't think anyone mentioned their race series.... with that 'other' club.

They turned a 2:01 lap time at VIR full course. That is legitimately quick. Especially considering the price and their efforts to keep cost of ownership down. For a turn-key, dedicated track car, it seems like a great option. I hope they're successful.
