Hey guys

Recently purchased a 2003 VY Calais and have begun to modify.

VE SS 18' wheels are on and have now turned to suspension.

A friend of mine is offering very cheap Lovells Superlow suspension for the rear and Super low King Springs for the front.
I know their will be a minor difference in how much it lowers the car (1 - 1.5 cm at rear), but will using two different brand springs have any negative effects i could be informed about ??

Thanks in advance
