This summer I plan on swapping in my '07 sti r180 .. And of course I'm researching axles, I'm fine with going with the side adapters; if its possible i would like try something a little stronger.. Question is do you guys know if the 280zx CV axles 27 spline will plug in the 27 spline sti r180 diff? I have a 260z with single turbo 1jz under the hood that will have around 420whp when tunned.. I'm just not sure the stock half shafts can hold up to light drag racing, or track days...
