HSD's installing question

Measure your current ride height from inside edge of wheel arch to centre of the wheel, then adjust the new coilovers accordingly ie. if you want them lower by 10mm then reduce the measurement, if you want them higher increase it. Obviously the ride height measurement left and right should be identical, front and rear ride heights can vary.

 

Note when you first drop the car onto the wheels after installing the new suspension it'll sit high, you'll need to drive the car a little before the suspension settles to the correct ride height.

 

See HERE for stock ride heights.

 

I would get a full geometry and alignment check done after installation.

Make sure you adjust on a perfectly level surface otherwise all your adjustments will be out of alignment. Also if you have any free weights or 25kg builders bags of sand put your body weights equivalent into the drivers seat and footwell to match your displacement onto the suspension when you're driving. Say you weigh 75kg (~168 pounds) put 50kg onto the seat and 25kg onto the footwell. Then go round adjusting your suspension. I did this to mine after using a sprit level and blocks of wood to get a level surface upon which I jacked the car onto the blocks. I fitted BC racing coilovers and after setting the ride height using this method it worked a treat.

 

As stated once happy with ride height, and after driving it for a few weeks to let the suspension settle get a full Geomentry setup done and your car shall drive much better.

 

 

Edit: Oh it took me 4 hours to do this as each adjustment will affect the other 3 coirners of the car, trick is little adjustments at a time starting with the heaviest corner normally the offside front (taking into account driver ballast)
