Drag radials like automatic transmissions, et streets/drags like manual. Both have + and - but the drag radials will work on a 6 speed with an experienced driver and some type of launch control. You can't spin them, they need to dead hook.

I also mentioned BFG's.. So I can see where the confusion came from.
I have had a lot of experience running both setups, BFG DR and the Drag Pack, never broken parts or had any of the FI cars I built break a part on a Drag Pack either, I don't sell them or have any affiliation with them. Just trying to save the guy some aggrivation. You can do a search and look what the guys on here are running that are fast. Some of them might be running the MT DR or the new MH? Don't know.
He was asking for drag racers comments.. I gave mine.
If you do have a point I am happy to hear what it might be.
I have had the same experiances. I did get a best of 1.531 on BFG 315 DR, but also broke a shaft. Once I moved to the Bias Ply on a smaller wheel I was able to have better and more consistant 60'ers. I used the cheap light weight 17" front Z06 wheel and MT ET Street. I think the vast majority of drag racers will concur with the ET Street being a little better than at least the 18 DR. Some are now doing pretty well with the MT DR, and this may be a good choice for the automatics? Best overall is still the drag pack, IMO, and that is a 16" rear wheel.

Very interesting your statements here! I have read the whole post and for some reason there is a "TENSION" with you.
Please if you would provide some Video's, with proof of the tires they are running -exactly as my set-up, with the Vette or vehicle smashing/running into the "WALL"! Please there must be "PROOF" of the set-up not just "I KNOW A GUY or SEEN A GUY......"
Again I have no issues with the set-up I am running! Perhaps eventually I'll go with some front skinnies to compliment the rears but till then - I'll be careful!
I've DRAG raced for many years, older Chevy's being the majority till now! I do thank you and will watch out for those walls
Thanks,Matt
I too run a stock Z06 radial on the front of my Z06 and bia ply in the rear. It is not the safest set-up. I have many hundreds of passes in my car, but what Nick is saying is true, it is best to also run a bias ply in the front with our ET street rears. My car is like an aaa fuel altered of past days, lol, and gets loose at speeds above 125 for sure. I am aware of the risks and willing to run this way, but certainly warn others. I think this is important when giving advice, eventhough I have not hit the wall, some certsinly have.

Thanks for all the input guys. I have a question. Seems that nobody favors drag radials. But that guy Paul Majors has national record with drag radials of low 7 second run, right? How is he getting away with it?
So is the problem with the radials the sidewall?
Are the Bias tires more like wrinkle wall sliicks?
I'm trying to understand the logic of all of this. People say do or dont do this, but they never explain the dynamics of it.
Team Major Sets The Bar in Extreme Radial
11/25/08 - Arriving on Thursday Paul and the team goes a 7.36 @ 203 right off the trailer in testing. The word was out we had the field covered by a minimum of 2 tenths. The next day we would improve on that with a qualifying pass of 7.25 @ 205 and 7.28 @ 204, setting the track records for both ET and MPH. Unfortunately we were plagued with transmission and flex plate issues that prevented us from making the call for the first round of eliminations on Sunday. Never-the-less we made our presence known on the West Coast showing the true potential of trunk mounted turbos, LSx based power plant and the Mickey Thompson drag radials
I guess some people have done it but I wouldn't even consider a 18" wheel for the track.For the street maybe but a 16" wheel has more sidewall and will out hook a 18 " wheel with a similar size tire.

Is there any thing special you have to do to run a 16" wheel? Will it clear the brakes?
So if I get some 16" wheels, then what kind of car would they be for? And what rim width and offset?

I've been 7.2s with my LSx mustang on drag radials. We run 30" drag radials, the tires are steel belted so they dont have alot of sidewall flex. The suspension must be setup correctly, we usually roll out with very little power. I leave with less than 6# of boost, as the tire gets planted you start throwing the power at it. They do not like to spin, if your suspension isn't setup right you get this 300' out...The suspensions are designed so they drive the tire into the ground, no IRS can do that.
We went 7.2 on our 2nd 1/4 mile hit and we've got less than 15 1/8 mile passes on the car this year. No twin 88s or 91s here, just a single turbo.

IIRC, Paul has a F-Bod style solid axel set-up under his car, if not the F-Bod suspenion it's at least a solid axel I believe. Same with Phil, a solid axel. also, auomatics can run a DR mutch easier than a stick car. Some classes require a DOT style DR...
The stick cars need the nice sidewall flex of the bias ply to help plant the tire and soften the shock, and thus the 16" wheel being the best. The CCW drag pack and 16" was made for the Vette, some slight grinding is often needed on the top ball joint. The cheap alternative is running the Z06 front wheel and an ET Street 17". Some are running the small GTO spare tire and wheel as the front, I don't think I would however? it is not rated for the speeds we see in the street/strip realm.

I'm familiar. It's the reason I wouldn't pick a corvette for a drag car.
Very true. many times I have thought about going F-Bod for a dedicated drag car. It sure would be cheaper that's for sure, lol. Even so, some of us like the challenge of trying to get fast times from the 6-speed and IRS cars. Actually, it's pretty hard to get one into the nines regardless of the HP, and takes actual driving skill.
