  • cornering (moved from suspension-"sway bars -match suspension?)"

    RGB has TRACK driving right. It applies at an autocross as well as road racing. For the very tightest turns the rear wheels are transmitting even more power and need the grip from reduced cornering load provided by a small rear sway bar.

    DO NOT try this on the street. This is race track driving technique. If you've got the car this close to the edge, you're going WAY too fast for the street. I'm not winking, I'm really serious about that. Driving this fast on the street is ridiculously dangerous to yourself and more importantly, to others.

    "Braking hard weight shifts to front tires. Starting the turn front tires grip. Next the care "rotates" (the mildest form of "oversteer" imaginable). Start to smoothly apply the throttle, the car stops rotating (because weight has transfered to the rear tires and now they are gripping better than the front). Full throttle. Apex. Minimal "understeer" off the corner that can be corrected with just a little more steering input and without having to back off the throttle. "

    This is right. With a V6 power/weight ratio, you should be at full throttle at or before the apex. If you can't do that because the rear will come around, your rear bar is too big. A very minor quibble is that I think you (usually) need to slightly overrotate the car (with the steering wheel) before the apex and be unwinding the steering as you exit the corner toward the outside edge of the track, ie "late apex".

    Good advice Bob. Again, don't do it on the street, and wear a nice helmet. [img]smile.gif[/img]

      Perfect.

      While we've gone back and forth on a lot of things, I really like your empirical way of matching bars (being able to put power down at apex, but not too much before)

      Speaking of track driving, I think I'm in for a fun time in a few weekends. Firebird Raceway Main track. The full drag strip is part of the track, so I get 5/8 mile of straightaway lovin' :D (and 14 turns to keep me honest)

        Jeff...check out the Sports Car Club of America National Road Races this weekend at Phoenix. SCCA uses 2/3 of the oval and the infield road course...there's always a bunch of Z06 Corvettes duking it out with Porsche GT3's and Vipers in T1 class and believe it or not there will be at least one and maybe two Camaro V6's racing in Showroom Stock B against the BMW Z4's and Miata's and SRT's...most of this board seems straight line oriented but if any of you can make it to an SCCA weekend, or NASA event with the Camaro Mustang Challenge race (just like a 1970's Trans Am race) it's a real kick. We're prepping two Camaro V6 cars for SCCA SSB right now and expect to have fun with them this year at Laguna Seca, etc in California...if you're in the neighborhood of Laguna, Sears Point, Thunderhill, or Portland, let me know and I'll arrange pit passes if anyone would like to see the races...Richard Pryor

          I'll be out of town in Buffalo this weekend for a friend's wedding, otherwise I'd love to come up. You guys will be at PIR I take it? I've heard great things about that track, need to drive it sometime.

          And I'm with you about about the V6's hanging in SSB - In ProAutoSports events I've kept up with and passed Z4's, Miatas, Mustang GT's, and many other competitive cars. I see a bunch of people renting the Z4, M3, or GT for a day to race them. I was pretty surprised to be able to pull on two of the RX7 race cars who were in our group, my street tires to their race rubber..
