I want to order some drag wheels for my GTO now.
What I need is a 15x8 wheel with 4.75 or more backspace. 5" would be best, 5,5" should work as well but it will shorten my track width. In general, is a smaller or wider "track width" better for drag racing? I guess smaller?
So there are 3 possible wheel choices, please let me know which is best:
1. Circle Racing wheels 15x8, 5" backspace
I found these wheels, but the Summit service told me that they are not good for drag racing: http://www.summitracing.com/int/part...7500/overview/
Do you also think they are a bad choice? Because size and price would be just fine. Weight isn't my biggest concern and aluminium wheels are much more expensive. The car will see the drag strip twice a year and tires are Nitto 555R (275/50/15) It's not a race only car where every lbs counts so if only weight is the Problem with these wheels I don't really care too much.
Are there some other reasons why I should not use Circle Racing wheels or Bart wheels? They are not DOT approved, but I don't want to drive on the street. Is there any danger if I use them for drag? (my 1/8 mile time with 235/60/15 BF Goodrich Radial T/A was 9.2 sec at 78.9mph).
2. US Wheel or Cragar steel wheels, 15x8, 4.75" backspace
The other wheels I found are US Wheel and Cragar steel rims, 15x8 and 4.75" backspace. Should fit, but I cannot use a bigger tire or it will rub on the outer side. For example: http://www.summitracing.com/int/part...834p/overview/
Weight is about 3lbs more than the Summit aluminium wheel and about 6lbs more than a Weld wheel (which is too expensive for my taste)
3. Summit Fast Five Aluminium wheel, 15x8, 5.5" backspace
If I would use the wheels with 5.5" backspacing this would shorten my track width about 38mm (1,5"). Not sure if this is a good thing.
If needed I could use my 0.25" spacers that I already have at home to get a 5.25" backspacing. If I use these wheels and spacers.. do I need some other lug nuts? I don't want to change the studs.
Please let me know which wheel would be your choice and why.
I like the number 3 the most, but I'm not sure which lug nuts are required and how to mount my 0.25" spacer if I need to.
