Cornering G's

2003.5 Mica Black P5
I've seen enough 1/4 mile times for a car known better for handling. Anybody out there able to check their skidpad performance? Any before (stock) and after numbers? I thought I've read .85 g's stock so with the right set up I would think pushing .90+ g's isn't unreasonable. I think the P5 handles better than many above it's class.

.79

it is nimble and responsive, but doesn't have great grip with its skinny (albeit performance oriented) stock tires
 
Whats up...I have a REV Speed with the G-force adaptor and I got my ride clocked at 1.05g's. I could go alittle more but I didn't want to burn my tires.
 
what increases g's? tires? sway bar? for a car that goes as fast as it does in the slalom, it's skidpad numbers aren't as high as it should be...?
 
Peak G's are different than sustained G's. Usually you'll have a hard time getting over 1 G with a tire that has a treadwear rating of over 90.

so is the 0.79 sustained g's? in that case what's the peak g? road and track's handling test showed the mp3 goes up to 0.92 i think, which is really stellar. what would allow the p5 to do that?
 
.79 sustained G's, yes

you can peak 1 g in many cars when oversteering heavily, but that can't be sustained around the skidpad
 
well i have to say.... if the MP3 can pull .92 g's, i am sure i'd be able to do that as well. i have the same suspension set up as the MP3, and although i dont have any numbers, i am sure i would be able to do that as well.

If you buy the MP3 Struts and the Racing beat springs like i have, plus a thicker front and rear sway bar, the P5 will definately be able to do that. I have seen a dramatic night and day difference between stock and my set up now.

You do not need to spend thousands of dollars on a suspension system in order to get your car to handle so much better.

Springs $200
Struts $480
Installation $175 (this can vary)

$755 To keep up with Porsches and Z06's? Not bad. Eat your heart out!

just to give you an idea of the difference:
Highway offramp stock: 60mph at the sustainable threshold before understeer
Same Highway offramp with almost bald tires: 83mph at the sustainable threshold before understeer

big difference i kid you not. also at much higher speeds between 85 and 130, the car is solid. Acceleration is slightly imporved as well.
Also, which is difficult to do in a front whell drive car, i was approaching a turn and was going through. i pushed the car to the limit, and at about 75mph it began to oversteer, and as soon as i let off the gas, the car caught grip, and the back end slid back into its orignial direction. Therefore i was at the limit of adhesion, and going past the slip angle of the rear tires.

Eveyone talks about how much HP they can get out of their block, whats the use if your car cant handle?
 
i was just thinking to myself, and i think the P5 can be made to oversteer or drift better then the sedan. the reason why i think this is because the center of gravity for the P5 will be different because of the hatch. if i am wrong i would like to know.
 
absolutly....the larger rear sway bar definately allows u to control your oversteer. however i am kind of dubious regarding the g-force adapter...they are accurate i am sure but not precise. figure a porsche does .9's...the msp does .85-.87. the evo VIII does .91. peace
 
im really curious about mine with the tein springs and 215/40-17 yoko avs es100s....theyre beastly tires
 
I have JIC FLT-A2 coilovers a 25mm front swaybar and a 21.5 rear swaybar AWR adjustable endliknks and trailing arms w/ uretheyne bushings 18" Enkei RPM2's w/ Toyo Proxes T1-s I also have Protosport Strut and under car braces on the way . I wonder if I can hit over 1. G on a skid pad ??????
 
when driving in a circle at the limit of adheasion if you can take a random object and place it on your window or the side of your door and have it stay there then you are probably at 1g
 
1G, sustained, on the skidpad is a pretty amazing feat... It's more difficult than it would seem, too. You need a very well tuned car, as well as an equally well tuned driver. The ability of the Protege5's grip is very underrated on the stock tires, which I would think would be the largest setback. Even changing my tires up to 205/50R16 Yokohama AVS ES100's, I've seen stellar increase in lateral and linear grip over the stock 195/50R16 wheels. And if you went to a 7" wide rim, pushing out the sidewall on the 205's even further, you'd get even better traction. If you look at cornering G's on a lot of cars, and tests, you'll see that a sustained 1G reading is rather difficult; It was a while back, December 2001 to be exact, that the SCC magazine with the G Games in it was released. The winner of the game, SCC/Wolfgang Hoeck's FD RX-7 pushed 1.035 to take the victory, all cars running on shaved BFGoodrich g-Force T/A KD's... It's not exactly easy to do, but it can be done, and the P5, in my oppinion, is an awesome chassis to have to work with, as would be the case with any Protege; It would seem that the chassis lends itself to wonderful handling characteristics, making it a joy to drive, regardless of skidpad results, but it has worlds of potential still untapped. Lets see what you folks can come up with, though. =) Seeing the first P5 break one lateral G would be awesome!
 
oh yes, the es100s own, i learned of their greatness on my friends wrx, hes ALWAYS driving fast and crazy, and never has to worry about grip
