Thanks for the words of encouragement :-)

So we're now ready to start bolting bits to the car. However, before we could get started, Nick insisted that the suspension arms and various undercarriage bits had to be shot blasted and repainted. This is for no other reason than Nick is a tart and likes things to be all shiny.

Next up was pressing bushes into the newly painted bits. For this we used Turner Motorsports solid or ball bearing bushes and standard BMW for the upper and lower trailing arms as they're ball bearing bushes as stock.

We also took the opportunity to replace the wheel bearings before refitting the hubs.

So this is what the underside looked like a couple of days ago:

And now with the subframe, arms and rear coilovers fitted:

You may notice that the nearside upper arm isn't nice and shiny. Sadly the painted arm had too much play in one the bearing housings so had to be binned. We'll get a another painted up but I'm itching to get this thing finished and tested so we're going to have to live with it for now.

So onto the first of the new suspension parts we are developing for the e46. We have been working with Quantum Racing Suspension and Cornering Force for the past year to develop the QRS X Series range for the M3. These are 4 way adjustable recirculating shock absorbers that generate far greater damping forces than traditional mono-tube dampers. The design of the adjusters allows for far more accurate control of damping forces and Quantum have the expertise and flexibility to build shocks to a specified damping curve. They are also much lighter than the 3 way adjustable dampers we have used previously.
