Kicking and screaming I brought the Mach 1 to the 21st century. My hole life the look for these cars were 15" magnum 500s with 245/60 up front and 255/60s out back. A close second ET slot mags or Cragar sst.
Let me start by saying my T/As are 10 years so they may have gotten a little hard. I've had my Mach on the road for 5 months and just over 400 miles. Well I have a traction problem. I mean bad! It's worse than the V8 pinto I built when I was a kid. At first It was humorous burning the tires into 3rd gear but that got old quick. I really didn't think a new set of 1984 technology T/As would fix the problem. Didn't want to go down the drag radials road. With a lot of thought I decided to go big but not to big. The hardest decision was 17s or 18s. I felt it was best to have more sidewall on this old car. Maybe if it had modern suspension I would think different.
Wheels wheels wheels! Weeks looking for the right wheels for the car. I was looking at chrome U. S. Mags Rambler wheels. I started to change my mind when I notice how many cars and trucks have them. Plus I don't have big brakes to show off. That leads me to one of or sponsors. Vintage Wheel San Diego. Found American Racing Magnum 500 VN50017 on there site. I seen the wheels on the web with the machined aluminum look but wasn't feeling it. But when seen the wheels with 2 piece polished outer rim I was sold. The fronts are 17/8 with 4.75 backspace and the rears are 17/9 with 5.5 back space. I herd to bye local when you can so I did. Even better they were maid to order right up the road in Corona California. U.S. Mags Rambler wheels China just saying.
Tires I went with General G Max RS I figured I would give them a try. Just didn't like the new tread pattern of the g-Force T/A. Don't know why just didn't and no way in hell was I going to put Nitos on my American muscle car. On the front went with 255/40 and 275/40 out back. What a difference! Now I can the power of the 408 to the ground. Did not feel any difference in the ride. Made a huge in cornering. With the springs sway bars and 17s made it all come together.
