    Largest width 18" wheels and tire 2nd generation F body with Full Ridetech coil over

    I am trying to make a decision to mini tub or not to mini tub. I am leaning toward not but wanted to see if anyone running the ridetech coilover package front and rear has any real world experience for the largest width 18" wheels and tires including back spacing for 2nd Gen Camaro/Firebirds. Any input is appreciated.

    My 71 Camaro 18x9.5 6" backspace with a pretty aggressive front alignment of 2.5* negative camber. The front rubs a little bit everywhere which tells me it's perfect. I run 265 or 275 35/18

    Same in the rear, you would need approximately a 1/4" spacer, I widened my axle to runs square wheels and tires.

    But you have a Firebird. Should be able to run 10" wheels without too much trouble.

    79 TA. I run an 18x10 Budniks on the rear of mine (8.5" on the front), 5-3/4" (rear) backspacing. 295 tire. Not tubbed, DSE drop leafs, stock rear axle. When the 295s are gone, I'm going up to try a 300 series.
