just like the title.

All you need to pull 1G in a stock LS1 F-body is a sticky set of race tires and good shocks.

but im looking to do this on DOT tires. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Define DOT? Kuhmo Victoracers are a DOT tire (as are Hoosier's).

Even cars with a full race suspension, like the LG '98 Z28, have problems pulling 1G on street tires. Sticky tires are the key to grip.

like the stock tires, just fresh ones. Or a set of comp t/a's. They ran an add a while ago with a vette that pulled 1g on the skid pad with thoes.

Yes a Z06 can pull 1G with stock tires, an F-body pretty much requires stickies. I have part of a GMHTP article I could email you that has the following skidpad results:
'98 1LE Z28 on BFG R1's: .89g
LG Motorsports '98 ZR28 on street tires: .88g
Turbo T/A on street radials: .84g
RLC Performance Engineering Z28 on street tires: .89g

Compare the differences in suspension aswell, and theres another thing. The ZO6 is setup to basically be a factory built racer. Both the Corvette and Fbody can pull some killer #s all around (handling, acceleration, 1/4 mile...) but i wouldn't say "just b/c the vette did XXX.X with these tires, if i use them, i can aswell." And i'd agree, the more stick you get from the tires, the more handling will be helped

FallsCB04@hotmail.com e-mail me all the articles you can. I want to see how hard I can push it. <img border="0" alt="[kaboom]" title="" src="graemlins/gr_bomb.gif" />

Here is the article I was referring to:

So thoes results would be further improved in the event that sub frame connectors, strut tower braces, and all that other stuff. Wheres the nearest skid pad in houston. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

If you want good skidpad numbers, and that's all you're interested in, it's all about sway bars, negative camber, and tires. Subframe connectors, shock tower braces, etc. just don't matter.

The real world isn't like a skidpad though, so you might not want to focus so heavily on that.

Im not really focused on it, but its all the fact of knowing that your car can do it. I dont plan on pulling 1g, I just want a car that can out handle most others. Another reason I asked this question is because I have this idiot friend that I was riding with. He gets on the 290, and decides to weave in and out of trafic at 130mph. No im not gona go do that, casue its just plain stupid. But im just one of the people that likes to shot around a big curve knowing that theyre car can take it, and being pushed down in the seat by the g's. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

On R1s,My car will pull 1.1-1.2 Gs no sweat (The LG car mentioned in that article)

The R1 Is a STICKY tire, and its really no match for any street tire. If you put the same tires we had on, the 1LE would have not been as fast.

Dont forget, the 1LE is 200#s lighter. We tipped the scales at 3750, w/driver, where the 1le was at 3526- 225 # difference!

none-the less, Still neat to see that article, That was what, 3 years ago, if not more? <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Yep, R1's were sticky tires. No longer made BTW. And any bone stock Camaro can pull 1g on a GOOD skidpad with R-compound tires. The size of the pad, the smoothness and the material all matter. Most Concrete is a lot stickier than most asphalts.

My stock 2001 Z28 weights 3450 w/o driver. Assume bigger wheels and a 225 pound driver and you will easily be right about 3700. So that is not uncommon. It will happily pull right about 1.1 on Kumho's on really good sites. Our Firebird with coil-overs, 11" wheels and all on R-tires will pull close to 1.3g's on a really good surface. BTW, 1LE's don't weight any less than any other Z28 that isn't loaded way up with options.

Make no mistake, todays ultra-high perf tires are pretty close to 3-5 year old R-compound tires. You can use that to compare, but "pulling G's" is just not a very accurate test of handling. It doesn't consider at all the transitional ability of the car (which is what makes it driveable). Hell a stock Camaro on GS-C's with a good site and pull .9 at the limit (but I'd never try that on the street, way too scary with the stock shocks).

BTW, I seem to vaguely remember that test (in the article) being done @ Englishtown in NJ. The grip there is not good (not the track, the lots where you autox). Routinely we'll go there and be lucky if we can beat good street tires by 1-1.5 seconds, where normally on sticky surfaces it's 2-3 easily. That site actually minimizes the differences between the tires (old asphalt that that marbles, not what you want with stick tires).

Sam, If you read the link to that article, you can see that the 1le tested weighed in at 3526. I have the article, and the LG (Cage, ect..) weighed in at 3750. Thats the difference.
