lateral G's
 

Please don't say search I did and couldn't find anything. But What I want to know is how many lateral G's does a stock 2nd gen Hold? Speciffiacally a NA s4. I'm looking for numbers from like a car and driver or motor trend magazine

iirc it was like .87 give or take a few hundreths for all fc's. this offcoarse was in stock trim, even shanging the tires/wheels or being out of alignment could realy chnge that either way.

I think you're in the right area, .87 sounds high to me for the car though. In any event, bumping that number up big time is a very easy affair on the FC as the chassis is a really great piece. Any of the upgraded spring/strut combo with a good alignment and sticky summer tires should definitely put you over the .90 mark. The right tire here, as with many handling tests, is key. Tires are extremely important but it's an area a lot of people skimp on. Think about it though, everything the car does is being transmitted through the tires (accel, decel, braking, cornering). Many people say "this tire sux, that tire is great" but it's really a matter of how a tire behaves on a given car. I've driven with tires on car A that felt terrible but on car B they feel much better. Find a tire suited to your car/suspension. Also, tests and numbers like this are totally subjective, they give you an idea of how a car performs but chasing numbers for performance seems like a stupid idea to me. Two cars that pull .95G on a skid pad or romp the slalom @ 71 mph can feel COMPLETELY different.

MT got .89g on a '90 TII (which is nearly 3000lbs). Keep in mind that tires have gotten substantially stickier in 15+ years. One would raise the skid pad number substantially with modern performance tires with a wider contact area.

For instance in this tire rack test the OEM Goodyear 17" 205 tires which are probably better than old stock FC tires were good for .89g on a 330i. The mid-level 225 RE750s were good for .94g, or ES100s like I have for .93g.

I can testify that the FC is great on a track in part because of it's dynamic character. It's performance seems to be greater than other vehicles with similar skip pad numbers, which is sort of a static test. Keep in mind that skip pad numbers also vary greatly due to the surface. I tend to think that most FC tests gave it a lower than actual skip pad number.

Then the real question is, how many times does even a really good driver actually use all .87-.93 Gs? on track, you get as close as you can as often as you can. On the street, front to rear balance is far more important. On a given corner the way the car feels is what makes you enjoy it, not if you can take the corner at 63.8 mph or 64.6 mph.
Just my opinion.
