M4 S55 Crankhub Fix
Tim's M4 came in for some much needed engine maintenance.
This week we carried out the following work:
Crankhub fix with Insane 4 pin crankhub
ACL rod bearings
Exhaust camshaft alignment
This has now made the 90k mile S55 engine much safer and more reliable to use on track, as we did at Snetterton the week after!!
