Helping (and hoping that) my foray into autocrossing and tracking my Bolt EUV will suck as little as possible while being as fun as possible...
I've thought of that... I'm hoping that gm factored those loads into a car weighing 3800 lbs. - or almost 4600 if fully laden with well-fed adults (LOL) - even without the racing factor. Ideally, it has the "beefieness" of hub and bearing assembly that one would think (same with the halfshafts) could cope with the loads... Time will tell.It will be interesting to see how the wheel bearings handle the side thrust these tires can produce, added on top of a boatload of torque from the electric drive. Since you are changing the camber settings, will the caster and bump steer change that much? I would assume you are going stiffer with shocks.
I have used these tires in showroom stock class, and they are amazing. Sooo sticky!
All street-legal cars rarely get above 75, and that's assuming one has a big, open course.What kind of top speed can be reached in a SCCA autocross course? Do you stay below the 92 mph limiter?
Well aware. Been doing it for 30 years now. LOL!I used to autocross a lot, and my 1972 240Z Datsun would rarely get out of 2nd gear. Pushed to 6,500 rpm redline in 2nd was 63 mph. Fast enough in a parking lot, where a lot of autocrosses are held.
The courses are usually short and very twisty. It's a drivers thing, more than just the car.
Problem is the class is a catch-all for ALL EVs.I pulled up the EVX (electric vehicle experimental class) rules and specs on SCCA, and wow! You can do just about anything you want to the suspension, but no changes are allowed on the electrical propulsion and management systems. The Bolt has a chance! I saw the Tesla is accepted, but no Fiat 500e or Chevy Spark. Those would be little terrors on a short course.
People love the Bolt on the BC Racing stuff and that's "one size fits all" type valving and spring rates.I'll be very curious to hear how things go. I'm sure the grip of those tires plus the coilovers will make the EUV a lot of fun.
I remember that Lamborghini and Callaway (golf, not the car builder) were supposed to co-develop ways to get carbon fiber reinforced resins done cheaper and more industrial-scaled for various purposes. Never heard much about that again. BUT that's your answer... Carbon fiber chassis is a must. Think Alfa Romeo 4C but electric. Maybe not 2000 lbs. but sub 3000 lbs. is a totally possibility because the Bolt is relatively "light" for what it is.It’s a shame that EV batteries weigh so much. If anyone can make a 2000 lb EV sports car with a couple hundred hp they would be a sheer terror on a tight autocross track 😀
