Its not happening. if you want it to fit and function you better look at aftermarket subframes or widened fenders

I have to respectfully disagree.
Our Tru Turn system consists of tubular StrongArm upper and lower control arms, our RideTech spindle [which is both taller than the oem unit and has a raised pin to lower the car], a different steering arm, and a special drag ling bracket to re-position the tie rods to optimize the steering geometry. Not only can you fit a 18x10 wheel with a 275mm front tire, but the camber curve, bumpsteer and caster alignment are also optimized.
If you use the 18x10 wheel you will need to use a 5.75 backspace. With that fitment [and the recommended alignment specs] the tire will contact the subframe just enough to possibly rub some paint off at full lock. IF you also incorporate shorter subframe/body bushings, you will also need to make MILD modifications to the outer portion of the inner fender for clearance.
IF you use stock height subframe bushings and/or put the 275 tire on a 18x9.5 wheel with a 5.5 backspace, no mods are needed to anything.
All of this is covered in the info and instructions

We have a 67 and a 68 Camaro in our own stable to demonstrate this, and hundreds of additional customers who have successfully installed this package.
Yes, it's tight.
No, if you do not align the frontend, it may not fit [or perform as intended].
Yes, you must use the complete package, it MAY NOT fit or be compatible with other brand components. [other companies and customers have verified fitment and function with other brand components]
Yes, you should be aware of header fitment. Some of the older gen 1 small block header designs are troublesome. Most LS conversions are fine.
