I currently run the C07 compound on my 63 corvette bracket car. (2200 lbs, tube chassis, 33/16 tire, 5.20's in the 1/8th) My 60ft times have been up and down. I was told I may want to try the D06 compound, was told it had a little more traction.
Anybody tried both compounds?
Thanks

My experience with the 06 & 07 has been that the 06 starts getting very inconsistent in heat. So depending on where you are and where you race, I have had better luck with the 07 – However (jump in here Ed) consider switching to MT. You will never look back.

i run a 3183 MT on my roadster tried the co6 didnt like it as much the roll out on the mickey is a bit shorter on the mickey too

I ran the D05 and C06 in several different sizes. As far as 60 foot times as long as track temperatures were reasonable they were good. The problem was tire shake and they were terrible in high temperatures and lower temps. The MT tires worked for me in much wider temp ranges both hot and cold. And my best 60 times were with the MT tires but that was not why I changed it was just a bonus.
With track temps under 60* and humid outside the D05 was on edge and may or may not hook. When track temps got over 150* which is not uncommon here in Texas Summers the Hoosier would start pulling up rubber off the track on the big end and would move around a lot. The MT tires worked better in a wider temp range.
I do not think the D05 or C06 will be an improvement for you they are softer and I think the C07 is probably best.
Which brings me to last thought. I think that the Hoosier tire should work on your car as it is plenty big enough and makes me wonder if you have some other issue going on? Like chassis or shock issue. Really with that size tire almost any brand and compound should hook.
Have you got good video to see what tire is doing? Are you sure it is a tire issue?
Even something like an ignition or carb issues can effect 60 foot times.
I am not a Hoosier fan but not 100% sure the tire is the problem and hate to see you wasting time and money on something that may not be the problem.

Thanks for everyone's input.

Curly1 - You are probably right about other things going on. My car is kind of a new build, I have changed the convertor since last season, still playing with shock set up. On days where I feel the car is doing good it will throw me a odd 60 ft at times, thats why I was wondering about the tire compound. I will probably go back with the C07 that is already on the car.

Thanks again,
Brian

18500's Here with a similar speed car. Happy with the C7 compound.

Steve - Thanks for the input.
I will probably go back with the C07

Thanks

Well if you are not really happy with the results of the old tire now would be a good time to try something new.
I think the MT is a better tire but you may have some other issues that need to be addressed what ever tire you run. Still a better tire is more forgiving.
