Slick Recommendation for stick car
 

We are trying to get a car set up this year and having a lot of difficulty with traction. 69 Camaro, 427, Jerico. Working with Calvert to ensure that was all correct and they said the tires are shot (20 runs) and to get a stiffer sidewall and harder compound. Tires are Hoosier 29x9 D06

I don't see any stiff sidewall tires in 9 inch on the Hoosier site. Mickey Thompson has a 29.5x9 (3056ST) which says it is recommended for manual transmissions. The MT site also calls out a different stiff sidewall tire for cars over 3,000 lbs (3360), but do not have it in a 9" tire.

What are others running for tires with a stick?

The guys I would ask are Brett McFarland, Ed Bednaz and Bob Broadbent.

Best tire I've found for best traction and longevity is the Hoosier 18200 30x9 D07. Usually get 80-100 runs before they go away. I've run the M/T tire and as far as I'm concerned they're not a good tire as I could never get more than 25 runs on then. Clutch settings and shock settings are also a factor plus tire pressure and launch RPM. A racepak can't hurt as well.

The MT 3056st is fine but I would recommend tubes in any of them running. A heavy stick car.

What clutch are you running and what shocks? Everything has to work together. If you are hammering the tire with the clutch there is no tire that can overcome that unless conditions are perfect.

We have a McLeod soft lok. Front has dual adjustable shocks. Springs and shocks are fast from Randy Mans. Rear is all caltracs with their 9 way shocks. We were suspecting the rear shock, but have been working directly with them (great customer service btw). After going through a lot of stuff we started looking at the tires.

We have been from 380-800 lbs on base and 9.7/11.8/13.2 on the levers as we have tried to work through. From 3800-5000 on launch RPM. Front shocks on the loose end of rebound and the rear on the stiff end. Various combinations of the above.

I have tried many, but Mickey Thompson has a 29.5x9 (3056ST) works for my 302, 5-speed.

Re: Slick Recommendation for stick car
 

All of that can work, but it kind of depends on your expectations. If you are really looking to go fast, and the basic car and engine are optimized, better double adjustable rear shocks and a more modern, smaller and lighter clutch could really help. I use advanced clutches from Rob Youngblood, but there are similar ones that are much lighter and more efficient than an older style soft lock. A bigger clutch like that has a bigger tuning window so they are a great clutch to start with, just know there are options if you want to go faster.

Another vote for Hoosier 18200, D07

Re: Slick Recommendation for stick car
 

Those Hoosier 18200 D07's are my personal all around favorite bias tire. The stiff wall Mickey is also very good and have had success with it.

Do you have Racepak with a clutch input sensor installed? That's your most important tuning tool with a clutch car. If you have any videos or data logs I'm happy to check them out.

X 3 on the Hoosier D07!

You’ll never get there without DA shocks on all four corners. I fought it for years.

Those single adjustable shocks are WORTHLESS and even more WORTHLESS with a stick. You need to be able to control bump and rebound separate from each other.

I doubt you have a tire problem. The other issues is your traction bars. I’ve never seen a stick car that wanted the bar running up hill, jacking the *** of the car up like a stink bug.

Get the bars running downhill and get better shocks. You’ll never get there with this shocks and I don?t care who makes them half assed work.

They may have great customer service but they ain’t paying you to test and tune their substandard shocks.

It is what it is.

Re: Slick Recommendation for stick car
 

so you are saying downward from the front bracket?

Re: Slick Recommendation for stick car
 

Whatever it takes to get the bar running downhill. Raise the back of the bar, lower the front or both.

That?s an issue I have with the bars you use. They don?t have nearly enough adjustment.

Like a ladder bar, the IC is always too short and too high with ANY bar like that, especially if you are making power or have a stick or worse you make power and have a stick.

So getting the IC as low as you can get it is how I tune them. I don’t tune stick/radial so I can’t answer to that.

I?m also a huge advocate of using the lightest flywheel you can find. Rotational inertia ends up at the tire and all the flywheel weight makes shock tuning different than it would be with a lighter flywheel.
