Thirdgen handling..
Not sure if this is the right place to post this, but does anyone have a vid of a thirdgen hauling *** around a corner or a turn, either on the street or on a course??Thanks

Yes drifting would be great to but I would also like to see one that shows just how well these cars can take hard corners without losing control if thats possible too...I hope Im making sense

I once blew through a stop sign and made a VERY sharp left turn, almost hit the far curb - luckily for my stupid behind, the road I turned onto didn't have any traffic at the time - they had no stop sign for that part of the road. I was doing close to forty, I'm very suprised the AquaTread (CRAP TIRES!) didn't break loose - but they did squeal and protest my radical turn. I had also mashed the brake pretty hard, too.
Wish I had a camera aimed at my silly self, so you could see it. It was intense. I drove like a grandma the rest of the time to work...
A typical lateral G rate for these cars is around .8, but this can be vastly improved with tires and various susension mods. You might PM RTFC to see if he has any vids.

What can they typically pull with good tires and spohn components? Not all out drift suspension, but what most of us do? (eg eibach, good tires, spohn rear components etc?)

read somewhere about a lowered iroc with shocks, larger rims and nice tires..and poly bushings (?) pull more g's than a stock c5...some food for thought
it may have had some more rear suspension components come to think of it

the 03-04 cobras use alot of the same suspension as the cobra R i hear so it should handle pretty good too. especially if you got rid of a few hundred pounds on them heavy pigs. LOL

I have now idea how to upload a Video onto the internet. The Video I have is terrible quality that was sent to me by a family member who shot it out at Calif speedway. But it shows me in this underpowered street car on street tires hanging with (I would dare say gaining on in the corners) a vintage GT40 raecar on race tires. He ate me for lunch on the straights.
If you have a way to upload it onto this site, then be may guest. I will e-mail the clip I have to you
Dean
ps. I did a skidpad test on this car a few years back and it pulled 1.07 g's on street tires. Does it transition? Your head will bounce off the side window if I turn without warning you
A v8 can only be made to handle close to this car if it is striped down and weight repositioned on the car. The last CMC race at Calif speedway showed the full race 3rdgens with V8's turning at best 1:59 to a 2:11 second laptimes on RACING RUBBER. I have turned a 2:09 on street tires and a pathetic 165hp out of the current 2.8 thats in it.

Even the newest Cobras use a variation of the 1970's fox body chassis - good for drag racing, but even with bolt ons not very good road-racinf wise. There are aftermarket race suspensions like Griggs that fix those problems. Thirdgens however, even with stamped steel parts and unibodies perform stellarly with just bolt ons, even better than 4th gens that have a "better" front suspension.
As for lateral g's, something like a stock SC or RS on 15" rubber came in around .80g stock, IROCS and GTAs around .88-.90g stock. Slalom speeds are in the pack with the sports cars of the time - RX7, Supra, 300ZX..... New cars do perform better... as they should.
The real key to good slalom speeds is the control of body motion and control of power application. Body motion is easy to change - stiffer springs, better valved struts/shocks, sway bars, and chassis stiffening. A well designed torque arm will help the power application tremendously, giving much more control over the power-on tendency for the car to oversteer. I would think that a modified thirdgen with all the right parts could run 1.05g and 70mph slalom speeds on street 275-40-17 rubber. That would be the same lateral g's as an enzo, with a slight disadvantage in the slalom (345 meats will do that).

you buy some Zr1 wheels, 9.5 inch up front, 11inch wide out back with some good street tires and all the bolt on's/goodies and setup right with good spring/shock combo, you can definately have a quick snappy thirdgen. slalom speeds should be close to if not over 70mph with that setup
it would be a stiffer riding car unless your using adjustable shocks but even then the spring rates might be closer to 750-850 lbs on front and 170-200 on the rear, maybe more than that. it would definately be a low car, which looks great in my opinion.

I just wish you would put some kind a trick forced induction on that VsixToy of yours and really wake that thing up

quite a few cars a well above that
paul_huryk as far as slolam numbers go I can't talk about the rest of the cars you mentioned but the rx7 from 86-88 was around 66.5mph or so slolam speed which is better then the slolam speed I remember the thirdgens having
and that was rated prolly with the basic 195 width tires while some of the others though havea still not great 205 width tires

. I am waking up the mini cooper with a V-tec motor when I find one for cheap thats useable. It'll wake up a little more when I get the 3.5L finished at about 250+ hp? It may even endup over 300hp with the tricks I am working into it while retaining full streetability and "uhum" smog legal statis, or so it will appear. Some day in the distance future I will have this car as a full time play toy with lots more time and money on hand to render it a complete weekend toy and would love to make a V6 motor for it that spins about 10k rpms and I'll throw a Richmond 6 speed into it if its still sitting unused by a certain family member. I have the flywheel and bellhousing assembly to convert it in the distant future. Until then it will remain a street commuter and retain the built 700r4 and a fairly radical but streetable 3.5L 60* V6. (Youknow the one I picked up from Bill- thank you again by the way.)

a good set of tires will fix up that slalom time a bit, cuz werent the stock tires (gatorbacks or something?) not the best gripping tires?

Motor Trend reported slalom speeds around 65mph in one of their articles for the 1987 Firebird Formula.

I'm sure an LS1 is the same weight (maybe less) than a 2.8/3.1 they stuck in the thirdgens.

think wides I heard is around 225 up front and 245 out back
as far as lateral g's think it was near around the .87-89 range for the rx7
again I agree not the greatest for my car either but just like a thirdgen responds fairly well to suspension mods
and I really need to find a way to get rid of the 4 wheel steering
