^^^^The front (gap as you call it) is the same as stock wheel/tire combo).. The 225/40/19 stock size and the 255/35/19 tire you are now running have the same OD, 26". The stock RCF tires you are running in the rear are 275/35/19 and are .6" larger in OD than stock, 26.6" vs 26.0".
I am running 255/35/19 in front and noticing no additional gap. I am happy with the extra width of the wheel, handling and more flush with the fender line. I am running 295/30/19 in back, same OD as stock, and did have lots of rubbing until I rolled the rear fenders flat. I now have occasional rubbing when I take a bump going to fast or when I have two people in the back seat. Otherwise no issues.
If you get bored with them, I'll trade you my 2012 Wheels + Cash.
Maybe now that’s the “newness” of seeing GSF wheels on an ISF has worn off I can say youre crazy bc the ISF wheels look waaay better than GSF wheels on the ISF, IMO...
The RCF wheels are similar (dimensions) to the GSF wheels and have been weighed by me (the standard wheel) and another forum member (polished wheel) the results were:
Standard wheels are:
9" = 25.5 lbs
10" = 28.0 lbs
And the Polished wheels are:
9" = 26.6 lbs
10" = 28.7 lbs
I would assume the GSF wheels are pretty close to the RCF polished wheel.
Had a lot of people reach out about fitment from another thread so thought I'd bump this thread.
- The rear will indeed require a roll
- As Lou mentioned above, did not modify front fenders. I am actually running a 12mm spacer to sit flush and match the rear fitment.
- Tires are Indy 500: 255/35 front and 285/30 rear
- No rubbing whatsoever
Well worth it!!
