Hi,
i am a complete new B on these cars, just bought a 71 Challenger.
I have been looking at the Ralley Wheels and i was thinking if the 17"x9" would fit my car... the front and rear end are completely stock, to my best knowledge.
And there´s drum brake all around
what do you guys think/know?
would they work?
Yes, they'll work. I run a 17x9 with 5" backspace and 275/40/17's on all four corners of my Challenger.
I do have a B body rear end with a 1" spring relocation in the back, BUT, I don't need it for that tire size. You would need it to go any larger in the back though. A 17x9 with ~5" backspace will fit all the way around on a stock Challenger.
I would caution you though- If you think your drum brakes are questionable now, they'll be scary with the 17x9's and big rubber. That's a lot more rotating mass, so my suggestion would be to at least upgrade to the stock 73-up (10.95") disk brakes in the front. I have the later 11.75" rotors and stock calipers on the front of my car, and 11x2.5" drums on the back. That set up works well with the larger wheels and tires on my small block car. I personally wouldn't drive anything with drums on all four corners on the street with any frequency.
