Hy, I just got the aluminium spydershaft. My car is lowered 1.5 inches with the ford springs and I have bmr lca's with the relocation brackets. Do you guy's think I will need the adjustable upper to solve any vibration that might come up, or will things be ok. My car is stored till april, so I'm just trying to get ready in advance.

Thanks,

 

I would really consider getting a UCA it will make life a lot easier adjusting your pinion angle. But it can be a pain installing.

 

check your pinion angle, if its at -2* or so you should be ok

but +1 to RICVA05'S comments

 

If you are lowered, you have to have adjustable

 

You might need it, might not like stated. Check you pinion angle to see if you need one. Even after lowering, my pinion angle was fine (although that's with using lca relocation brackets which might have moved the angle a little to where it needed to be).

FWIW, a bit of a PITA to put in, but it can be done.
