You never felt any sway? Even in the 100+mph range?

What kind of pressure were you running? Did you have full suspension? Cage?

I'm not doubting you, my experience has just been different. My car was virtually stock suspended with the addition of ET streets. It swayed as soon as I put them on. I can think of at least 4 other racing friends that mentioned exactly the same thing.

Some of the sway could have just been newbies to the feel of a bias ply tire. But from my experience (all be it far less than many of the posters in this thread) slicks and radials together = sway.

I wonder how much HP Rich was running with his 26" ETs (and had no problems), in compairson to your current setup?

I believe he may be running more power than me.

I ran the ET streets with street radials out front for a couple of years with no sway at all. But as I said in a previous post I put the air in the front to the manufacturers maximum to make them as stiff as possible and to make them run on just the center tread. But I never ever ran less than 16 psi hot in the ET streets as per Mickey Thompsons recommended minimum.

For example; when I had a 12.40 car (cam and bolt-on's), I also ran 16" rims and the 26" ET Streets. Sometimes when I shifted to 2nd the ETs would break loose and the car would get a little scary.

However, now with a low 11 second car and the correct wheels and slicks, the car never gets loose.

Exactly. I'm currently running 275-60x15 Hoosier drag radials and have zero traction problems.

Were you running your ET Streets (possibly 26") on 16" rims w/ low-profile side-walls?

The 26" ET Streets are going to have a harder time holding that power than the ET Drags... why not get a pair of those? You can't drive either of them in the rain, so neither are really "street tires" in my opinion.

Also, the increased sway up top is due to you not running skinnies up front (actually it's due to you running such a wide tire up front).

If your car isn't setup properly for drag racing, don't expect it to drag race well.

There's a right way and a wrong way to go about this. Guess which one you have.

If your not willing to change why did you ask the question?

lol you guys crack me up. Can't a guy ask how to do the best with his setup and get answers that don't include "change your setup"? Like I said, the car is used more on the street, and I just wanted to see if there was something I should know about running with what I have, or maybe utilizing what I have better thats all.

I'm not doubting you, my experience has just been different. My car was virtually stock suspended with the addition of ET streets. It swayed as soon as I put them on. I can think of at least 4 other racing friends that mentioned exactly the same thing.

Some of the sway could have just been newbies to the feel of a bias ply tire. But from my experience (all be it far less than many of the posters in this thread) slicks and radials together = sway.

I can't say it was stable as a rock. But nothing alarming. The car has 1LE springs/shock/and swaybars along with a Spohn torque arm and tubular LCA's. I was running over 140mph and like I said, as long as you stayed straight, no problem. If the car got out of the groove, it was best just to shut it down. Of course, that is pretty much true with any car running that quick.

You also crack me up! Apparently you’re looking for the answer you “want to hear” (that those small 26” ET will work just fine) while rejecting the answers you really “need to hear” (bigger slicks to handle your HP and not break loose). And, you only use the slicks at the track, therefore it doesn't change your street package.

For example; when Rich implied the 26” ETs should work without any problem, you immediately cited Rich’s credibility on the matter, whereas about twenty other people told you they were too small for your HP and you discounted those inputs.

I sure hope someone on the forum will be able to provide you with the “magic set-up” to make those 26” ETs work for you without getting your car unstable when you break them loose at the track! Then you'll have the answer you're looking for. Good luck!
