Few updates on the 4200:
EBC blue pads fitted on the front, supposed to be better for track use, we will see.
F1 fluid leaks, found the return pipe rubbers leaking and non-standard clips fitted in I assume previous effort to fix
New hoses and correct clips - no more leaks, also re- wrapped cables in the cloth tape (not shown in pic)
To aid the access had rear bumper off and reverted the exhaust back to stock, previously was straight through rears.
Old exhaust as fitted below
I must be getting old as prefer the original sound, engine noise rather than exhaust note
Old pipes on eBay if anyone interested!
AC leak, after getting the system checked after condenser repair and dryer replacement a small leak was found at the expansion valve, so 4 x o-rings replaced. It would have been very easy to do while the dash was out for the matrix job. Anyway doable with cut down allen keys and the normal struggle.
Thinking back it was obviously leaking as covered in oil from the system.
Hopefully that’s it solved.
Not much left to do now apart from swap the front subframe out!
