PENSKE are full race, so they only last about 2-3 race seasons before a rebuild/refresh service is done. can't say how the other brands last, but I can't imagine they would wear out fast enough to warrant not buying one.
I have owned a lot of cars okay. A lot of makes that were imports and domestics. I'm new to the F body world and what I find shocking is how much makeshift work is done. Nothing fits out the box people are always chopping, welding, bending something into place. I just can't take it this is not supposed to be the norm.
