I have seen the Skidpad rating for a S4 T2, but been wondering how does the GTU do ?

 

what's the skidpad rating for the TII?
I know that the 86 SE tested at .88.

 

I bealive i read .84 it was that, or .82



Aww C'mon someone must know.

 

Yo,


1989 GTUs per Road & Track:

0.81g

KS
1989 GTUs "I ain't gonna tell you what it did the 1/4 in."

 

I can't believe the numbers are that low. Is that the crappy stock tires making the number so bad, or what?

ive heard that the 86-88 s4 n/a's made .86 and the s5 n/a's made .89. i dont think that a a new protegé can outhandle any rx7's

 

Don't put too muck stock in skidpad numbers; they're a very unrealistic measure of how well a car handles. The smooth, flat surface of a skidpad bears no resemblance to a real road, which is never smooth, and may have bumps, dips, ripples, camber, etc. It's really only a measure of the outright lateral grip of the tyre, which is irrelevant if the suspension can't keep those grippy tyres of the uneven road surface. A car with good skidpad numbers won't necessarily handle or grip better than one with properly sorted road suspension.

 

Ohh, i was worried to see that the T2 did better than the GTU, yet the t2 weighs more.

Can someone tell me exactly what all makes the GTU different from a GXL.

I am getting a GTU soon, ,only needs a Apex seal.

 

ummmm.... do you know what that means?????????

or was that a joke????

You've got 270 posts so you should know, right????

 

All i ever heard was .89 for the N/As and .91 for the TII's

 

Enough with the guessing. Here are the actual test numbers from the magazines:

89 Turbo II: .85g
89 GTUs : .86g
Both on 205/55/VR16 Bridgestone Potenza RE71 on 16*7 wheels

(The GTUs and Turbo have the identical suspension and tires, but the GTUS is nearly 250 lbs lighter)

89 Convertible: .83g
205/60/15 RE71 on 15*6.5
Motor Trend

88 Convertible: .82g
205/60/15 RE71 on 15*6.5

(The GTUs tested must havebeen beat to hell beacuse it put up some lousy numbers in this test. It ran 0-60 in 8.6 secs in the test. Mazda claimed 7.7 secs. Also, how can a car 200+ lbs lighter than a Turbo with the same tires and suspension produce less lateral grip?)


By the way....GXL, GTU, GTUs, Convertible and Turbo RX-7s never came on crappy stock tires. Bridgestone Potenza RE71 was standard equipment on all non-turbo RX-7s and S5 Turbos and at that time it was arguably the best tire in the world. Its equivalent today is the Potenza S-03 Pole Position. the S4 Turbo came on Goodyear Eagle VR55 which was not a bad tire either.

 

Yes i do know what an Apex seal is, there are 3 per rotor, they rest in a divit at the tip of each rotors point. But when considering the price of the car, this is not a problem, hell i think i could scrap the car for more than i am paying ($400)

And he is not sure if it is a Apex seal, he assumes it is, becuase it is Blowing white smoke, but still runs.

 

the 86 n/a did do .88 in the skidpad. I've got those magazines that came out in 86 where they were testing the car.
