I want to change from my Cobra-R's to a Weld Draglite set-up.
15x8 rears, 15x3-1/2" or 4" fronts.
What should the back spacing be?
What's a good tire size for this set-up?
I will be using the fronts for the street and the track. So radials on all four.
I have 4 lug.
Thanks
15x3 with a 165r15 on the front and a 15x8 with 5.5 bs on the rear. as far as rear tire sizing that is up to you but i always run a 255/60-15 on a stock spring car if its dropped 2 inches or so a 235 or 245 fills it up good.
Personally if it is a pure track car I would go with the 15X3.5's but you said it will be a street and track car, so I would not use a 3.5 wheel or a 4 inch wheel, I just put some weld rodlites on my car 15X8 w/5.5 and 15X6 w/3.5bs and for tires I ran a 235-60 in the rear and a 195-65 up front and that is the size I would recommend for you.
