I wouldn't run the spare TIRE that fast, but you could certainly use the rim with Moroso drag skinnys.no164ford said:I read were guys say to use your stock spare tires for skinnys during drag raceing, Is that safe at 100 mph, and will the track let you do that? They also clam that it takes 0.2 seconds off your time that seems like alot, How much do skinnys help your 1/4 mile times?
You cannot run the spare tire because they are only rated to 50 mph. You can get speed rated tire (I think there is a VW size that fits) or a drag tire and you will be fine.no164ford said:I read were guys say to use your stock spare tires for skinnys during drag raceing, Is that safe at 100 mph, and will the track let you do that?

I just noticed it and I could SWARE its new...I dont know if the 6+lbs is = to 110 dead but I think its something like that. Yes the VW tires are/were used in the past. I think the ones 392 use are special tires that are a lighter weight.

I put a 1/2 inch spacer between the Kmember and body, that gave me more room, but not enough. With the scoop, and a custom made carb air box, I can now use a 4 inch K&N with there top filter. This will allow enough air flow for 6,000 rpm+ runs, plus give a direct outside air inlet.
Here are a few shots of the scoop and carb air box.

When completed, it will have a smooth transition from the hood to the scoop to blend it in. My garage has a layer of fibleglass dust on everything now.
Note: My front skinnys are cheap Kumho 758 T rated tires, which are fine for short runs at the strip.

fastsc92 said:its not the weight that makes the difference, its the rotating mass. I have read that 6lb of rotating mass is equal to 100lb's of dead weight in the car. So if you reduce some of your rotating mass, and friction, you are saving a lot.
