Hello,
I'm thinking of putting a pair of 17"x8" 4" BS -12mm offset Torque Thrust IIs on the back of my 80 El Camino. I picked up a couple of 17"x7" Torque Thrust II rims with a 4" BS and 0mm offset that are mounted with 245 45 17 tires and they fit perfect for the front. I have 2" dropped spindles also and the combo clears just fine. Sure, I could put the same size rim on the back and be able to rotate them but was thinking that later I might think...Why didn't I put a wider rim in the back? I have another pair of the same size tires, 245 45 17, as the front size that I was thinking of putting on the 17x8 rim and maybe later going with a 255 45 17. I don't think I want a 9.5 wide wheel since it only comes with a minimum backspacing of 5.56" which might be too much for the Elky. As a side note, I had a pair of the factory OEM 16" IROCs previously on the car that needed a 1-1/4" spacer/adapter in order for the rim/tire combo to clear the frame. When I put the TTII 17x7 wheel/tire combo on the back; it does move the tire outward nicely with the spacer/adapter. I have about 2" clearance from the tire/rim combo to the frame both in front and behind the tire. The tire is about 1/2" away from the rear fender lip, which isn't rolled since it doesn't rub. If I remove the spacer/adapter then I have about 1" clearance from the tire/rim combo from the frame front and rear and about 1-3/4" from the rear fender lip. Attached are a couple of pics of what the 17x7 wheel and 245 45 17 tires look like with the 1-1/4" spacer adapter on the back and a second pic with the spacer adapter removed. Actually, the tire/rim combo doesn't look too bad without the spacer. I think with the 17x8 and the 4" backspacing, plus the -12mm offset, the distance from the tire/wheel to the frame would be about 1/2" and the extra 1" width would leave about 1" gap from the rear fender lip. The 17x8 could run the extra pair of tires I have but I could probably run a 255 on it also. However, having the same size rim/tire combo at all four corners would let me rotate the tires to any corner. My calulations could be off a little. I'm going off the Summit Racing website for the rim dimensions. Any comments appreciated.
