Videos - Viper TA autocross and road course

Are you running caps?

Lowering caps? Nope, stock suspension. After seeing early pics of these cars on the corkscrew at Laguna Seca and other tracks, no way I'd lower one that was tracked.

Some of you guys might get a laugh out of this video, but I felt it important to share. This is how your tires can surprise you, after about 15 minutes of hard laps. I entered this corner at the same mph as previous 9 laps, but when I went to hit the brakes (hard braking in this zone) the tires were gone. The car slid for a very long way, and steering did nothing. Almost saved it, but decided to take it off track since cars were closing in behind me.

Street tires (Michelin Pilot Super Sport) can be unpredictable, once they get hot.

Glad to see you had ample run off .

Pretty good track for that, except for the drop off from the pavement to the grass. Didn't scrape though!

If you aren't sliding, you aren't trying

Tony,

Thanks for sharing that vid. Most people wouldn't do that, but it really shows that you have to be very aware of your tire heat as the day goes on.

Hmmmm Ben K and I ran them at COTA without any issues at all. With the offsets on your wheels I think you'd have rubbing issues before bottoming out at the base of the corkscrew.

I wasn't worried about tires rubbing, more about the front splitter. Ben did rub his front splitters, he told me. When corning hard, those splitters come to about an inch above ground on a stock height car. Both of my Gen 5 Vipers have lowered themselves at least a half inch, after miles and track days. Springs will sag with hard driving. Yours is probably even lower now, than when you first put the caps in.

Pics like these (stock height)



My tires do get tucked on corners, but no rubbing at the track.

Might as well have all 3 flavors.

Probably not the fastest corner there but here's another.

Doing my best to get my paw up there! This is in turn 10 getting the back end of the car back where it should be.

What suspension are you running on your car?

CCCCCombo breaker!

Awesome pics, love seeing Vipers on the road course!

MCS Singles from Woodhouse. Set up to stiffest rebound in back, fronts two clicks lower.

Just about a big breaker. You can see in this zoomed shot where the steering wheel position is. Keep in mind this is a left hand turn. That red stripe on the steering wheel has been coming in handy analyzing some driving in video and some pics.

I'm confused, how is the car turning left and the wheel is turned right? haha

Someone never watched "Cars"

Hehe, damn sure was not a left hand turn there for about a second!

[Nine Ball]

LOL! You won the drifting contest then? haha

Bought time I won something in that damn car!

Tony and Andy,

I started to think that maybe it wasn't possible to get enough grip on flat track (no banking) to scrape the splitter, and still suspect you may need both corner banking and heavy braking to load one front corner enough as that's the combination where I scrape. Are you guys maxing out, or close to maxing out, both the lateral and braking G Meter on that track. I'd be afraid to run mine with slicks when the Corsa's max out the front springs/sways on two particularly demanding corners.

[Nine Ball]

Bruce, here is a pic of my G-meter output from the event. Funny that I almost maxed out the acceleration one, also. Likely from this Start-Stop event:

Good demonstration video of slightly slipping the tires to achieve max grip! Heard years ago that max grip was with a 10% slip angle...not sure how broadly that applies to different tires now though.

No doubt that's the kind of place you'd see a 1.46g under acceleration. For fun I should try videoing a session with the G meter being shown, reset to zero, see what it shows all around the track, and what it is in the one banked corner/brake spot on my home track where I frequently scuff the splitter. I bet that's the only spot I see the 1.50 braking g's, and maybe the 1.50 g cornering at the same time. I think I'm barely into the .7g acceleration, IMS, and probably significantly lower as you roll on the throttle as you come out of corners in the lower gears.

Kyle, don't let Tony fool. You most definitely were making a left turn.

[Nine Ball]

HAHAHA Euro style.

[FrgMstr]

Hehehe....
