You'll just have a VTiR box with a 4.7FD.. Why not go further with a 4.9FD? (depends on your driving and project)
Also your 2nd and 3rd gears are much longer to a Type R.
No need to change the hub. Stud itself can be replace.. go wreckers and pay $5. Repco and such might sell them too. Not hard to replace if your mechanical minded. GL
What adjustments did they made? toe and camber? or just the toe?
The toe looks fine to me.. I prefer it to be on 0 though.
Camber is a bit whack.. might need some camber adjustable chuck in there...
Yes you can use them.. don't whats needed to be done in order to be fitted. But it's been done. Since the LCA is shorter compared to stock EK ones. It'll ruin your camber settings.
