New clutch and Flywheel courtesy of Bimmer World. A clutch masters kit, with their aluminium Flywheel.
Started bending up the bars for the cage today.
Got the head back from the flow bench guy.
Now we can install the new plus 1 mm size valves.
I decided to get rid of the steering box and install a steering rack. Some of the grp 4/5 car had this done and few others have done it as well. We removed the box and cut out the mounts and threw away all that old heavy steering links, steering arms and box, sourced an old manual 320 rack (rear steer that is close enough in length to make the geometry work) milled out some brackets to hold the rack and now we are in the process of mounting them to the subframe.
What the subframe looks like with the box and mounts still attached.
Pile of old links etc…
Steering box mount removed.
Preview of steering rack mounting.
Pictures of the steering rack with its new aluminium mounts.
The aluminium mounts are in two pieces that bolt around the rack the mounts are bolted to two steel brackets which will be welded to the subframe.
Mocking up to the subframe.
We cut the steel brackets down size and notched out the subframe where they will be welded into place.
After updating the rear subframe and trailing arms , and the planned change to coilover shocks ( stock has the springs on the trailing arms ) we need to modify the shock towers . actually they are being completely redone from scratch . this is not an uncommon practice, take notice at the more serious race cars and you’ll notice the rear shock towers coming though the rear package tray.
Below is the stock shocktowers before we started.
The stock tower is cut out.
Frank has worked his sheet metal Magic and formed up some fantastic new shock towers.
Placed in the hole for refineing.
And tacked into place.
And with the “loner shock” for mock up.
