I dont want to go with 15´s by all means and so I decided to keep the same tire outside diameter but to decrease the rim diameter by using 18´s (talk about the rear wheels).

Now I wonder if it makes a difference if I go with 20 or even 22 inch or with 18 and therefor more side wall height (would be one 1-3 inch more side wall, depends on the used tire).

If so I would go with M/T drag radials or maybe BF Goodrich´s DR, you can give me a recommendation on that.

Meanwhile I saw that they also offer 20" DR but how I said, I have been told the magic is in the side wall height.

In the members rides gallery I see almost only 20 and 22 inch wheels and I cannot imagine that none of that cars got a punchy engine, so what is your experience?

In your opinion, will I improve traction by going down to 18" and what about 20" DR?


Thanks Hannes Slanec

With a twin turbo 540BBC your going to have tire smoke with anything short of a pure drag racing slick. There will be no difference in performance of a 18 with a drag radial and a 20 with a drag radial.....there both going up in smoke at the crack of the throttle. Put 19,20 or 20, 22 and then get another set of rear wheels for drag racing the car
