Yes and no. The Xpower ones as used on the ZR are the same ones for the 25 so they will only lower the ZR by 20mm at most. But they are branded for the ZR specifically, it's just that there's no difference between them.
heres a question for you clever lot.
I want to lower my BRM ( i also want a lot of other things but we havnt got all day )
anyway as standard its lowered already 20mm i believe over the standard 200.
so am i looking at getting lowered springs for the 200 that are a 30-50mm drop so that ill get a 10-30mm drop ... or is that just too easy ??
