I've asked a couple people, and have gotten different answers each time, are ET streets easier or harder than normal street tires?

I'd like to try some launches on ET streets, but don't wanna break anything! In doing so would it be harder on my drivetrain because of the added traction, or would it be easier, considering they're a softer tire and capable of "absorbing" some of the energy and not transferring it to your diff and/or tranny?


Right now I'm running stock diff and tranny (wanna get the braces but not enough $$ right now).

Thanks!

Anything with more grip is automatically going to stress the drivetrain and suspension more. Since the tire has increased grip it will not spin as easily; this means the drivetrain/ suspension is operating at much higher loads.

Drag is really going to work the tranny, clutch, diff, diff mounts, PPF, axles, etc.

Putting the tires on and trying them out isn't going to automatically blow everything up, but they most certainly make the car have to work harder. With the amount of power you make I really can't say what your true risks are, but it's safe to say whomever claims sticky tires are easier on the car is a complete idiot.

 

Gotcha. Thanks a lot Damon!

Might be worth trying once, but since the car is now my daily driver, I don't wanna take any chances breaking something really expensive...

 

I daily drive mine. Only thing I ever blew up at the track was the motor I don't count the engine fire, that was on the way TO the track

I put the new motor in 15 months ago; it already has 20,000+ miles on it. I certainly do spend quite a lot of money on just upkeep of the car with the amount of driving and competition I do. Things like suspension bushings, brakes, rotors, tires, entry fees etc add up.

 

ET Streets will help with the Diff and Diff mounts cause you'll get sidewall flex to absorb the pressure and wheel hop. But it will kill the axles pretty quick.

How will the diff be fine and the axles not? The two are rigidly connected together. So are the diff mounts.

Sidewall flex does not magically subtract force from the system. Fact is the tread is stuck to the ground harder than a street tire. This means that the diff and drivetrain automatically see higher loads. Period.

The sidewall flexing may absorb some power for a moment but it is essentially a spring and doesn't store force; it will still release its stored energy almost immediately.

This is getting more complicated than need be. If the tire has more ability to resist spinning, then the system attempting to rotate the tire MUST be operating at higher loads. It's that simple.

 

i think he meant to say the axle will break before his diff and ppf

 

Less wheel hop = Broken axle instead of broken Diff. From what I've seen at the track, Vosko is right. Carl

 

Because the axles will twist and twist and twist till they snap. It might take 1 launch or it might take 10 but everytime you launch hard on ET streets the axles will twist a little untill they snap.

I read about one guy drawing a straight line on his axles then after a day at the track the straight line was now curved from one end to the other 1/2"

That's a normal "racecar" thing and suprising to most people. Just be certain to use a magic marker, you don't want to scribe a line into the metal!

 

if you plan to drag race you are gonna spend money or spend it later.... i tried to spend it later.... it was a major pain in the ***

 

Also, dont be shocked if you spend money again and again and again haha. Alot of times its not "sooner or later" its "sooner AND later" lol

I just raced my car last night (Mid night drags)
(No time's)Drag Strip event

I was lended some ET streets on FD wheels
and WOW the traction is unreal

The clutch was not, it was slipping bad in 2nd and 3rd
had to let off the gas and then re-floor it

I did about 10 passes (low attendance)
The weak clutch might of helped in the "no breaking department"

But I will buy a set for my self!

Theres a local Co that makes heavy duty axels for honda's etc
I will check into having a set of stage 3 axles made for me in due time

If they can make you a set of heavy duty axles for a good price let us all know. I might be interested in a set if the price is right.

what about those axles RP has been using...
