Voodoo U4 Compound Recommendations
 

The tires have now been extensively tested in U4 and G6 driving conditions and here our our compound recommendations: (using Crawler innovations DW standard size foams)

U4RC: Both compounds are excellent for high speed U4RC track conditions! Both compounds deliver high traction coupled with a super smooth and controllable drive at track speeds.
Note: In cold conditions, consider using the gold compound. It's a great cold/wet weather compound, even in sub zero temps.

G6: We recommend the SILVER compound for G6 events. The silver compound EXCELS in technical rock sections and also digs in hard at low to moderate speeds on long hill climbs.
Note: Just like U4RC, in cold conditions, consider using the gold compound. It's a great cold/wet weather compound, even in sub zero temps.

Scale: We've done very little testing along these lines as the tire was designed for moderate to high speed application. If you do scale type driving we'd like your input! Our guess is that the silver compound will work best for most drivers.
