Has anyone tried the apparently new coil over system from Pedders yet ?
" Pedders now has an adjustable coilover suspension kit to suit your next custom car build.
The award winning Pedders eXtreme XA Adjustable coilover offer exceptional ride and handling etc. WITH the ability to raise or lower the car without changing the coil pre-load OR lower spring seat position. Has 30 position bump AND rebound damping yada yada yada.
365mm minimum extended length & a maximum ext length of 405mm and a bunch of different spring rates apparently.
Could be worth a look
