From what I have seen. Some people can get away without them. But for the price it's probably worth having them done at the same time as if you do need them you will need a second visit.
I shouldn't really comment as I haven't had mine lowered but didn't want to read and run
Not needed here either with extensive suspension modifications. You may need camber bolts, can't remember if it was front or rear, depending on how you want the suspension dialled in.
thanks for the response guys, i'm currently looking at the Roush Adjustable coilovers which do 1.5 on the front and 1 on the rear from factory. AM recommended camber plates with them, but they are probably just trying to sell more
@steeda_UK do you have an equivalent spring and shock set for a similar drop?
Hi [MENTION=19130]SamH_[/MENTION] yes we do Steeda shocks and springs set up (both adjustable and fixed rate shocks) with a variety of springs to use, with different drops. 1" all round, 1" rear and 1 1/4" front, and 2" extremes as a guide. Plus we offer rear spring spacers to adjust the look and rake if required.
Plus we can supply KW V3 coilovers if you want a fully height adjustable (but more costly setup). As I mentioned above, a 1" ish drop should see you OK with alignment but significantly more could need camber assists as above. Our Camber plates work with KW Coilovers too.
